THE FIX OF THE WEEK

Every week, we review new fixes submitted by our Direct-Hit users and pick our favorite “Fix of The Week.” These are confirmed, experience-based fixes directly from technicians and shops. You can find this and over 3.5 million other confirmed fixes in Direct-Hit with a 14-day free trial. This week, our favorite fix is about the driver’s side front signal lights not working in a 2015 Chevy Silverado 3500 HD LT.

The Vehicle:

2015 Chevy Silverado 3500 HD LT

The Problem:

The driver’s side front signal lights do not work. If you turn the park lights on, the arrow in the left mirror comes on steady.

The Diagnosis:

After scanning the vehicle for trouble codes. I found codeB3948(Left front signal light circuit open) was set. I then went about removing both bulbs on the left front signal light as they were showing to be inoperative. When looking into both of the bulbs, the turn signal filaments were broken off and were touching the park light filament. This is what was creating a back-feed voltage to the arrow light on the mirror, which explains why the arrow light continued to stay on.

The Solution:

Ultimately, we replaced the two signal light bulbs, and cleared the code checked operation. All lights are now working correctly.

You can find this and over 3.5 million other confirmed fixes in Direct-Hit with a 14-day free trial. This week, our favorite fix is about a passenger front power window in a 2015 Cadillac ATS Luxury 3.6 V6 that intermittently stops and reverses when closing.

 

The Vehicle:

2015 Cadillac ATS Luxury 3.6 V6

The Problem:

Intermittently the passenger front power window stops and reverses when closing.

The Diagnosis:

After duplicating the concern I noticed it only does this in the “Express-up” function. I first tried to perform a generic recalibration—by opening and then closing the window and holding the switch for 3 seconds—and this did not correct the problem. Before spending more time, I searched Direct-Hit and found a GM TSB which outlined Unwanted Window Reversal, along with a procedure to check the window track/run channel for drag. The window glass was not excessively tilted in or out, and the window operated smoothly right up until it reversed. The TSB stated not to replace the motor or regulator for the reversing concern, but considering the window opened and closed so smoothly, I decided to replace the passenger front window motor. The bulletin had outlined the relearn procedure as well which helped make the repair easier.

The Solution:

Replace the Passenger front window motor.

Extra Tech Tip:

Starting with the window completely up, press and hold the power window switch until the window is fully open and continue holding the switch down for approximately 5 seconds after the window is completely open. Pull the power window switch up until the window is fully closed and continue holding the switch up for approximately 5 seconds after the window is completely closed. The window is now reprogrammed

 


2012 Honda Pilot No Crank No Start – FOW 06-23-20

You can find this and over 3.5 million other confirmed fixes in Direct-Hit with a 14-day free trial. This week, our favorite fix is for a no crank no start 2012 Honda Pilot EX.

 

The Vehicle:

2012 Honda Pilot EX 3.5 V6

Additional Vehicles:

2011 Honda Pilot, 2013 Honda Pilot

The Problem:

The vehicle came in as a no crank, no start scenario.

The Diagnosis:

After verifying the battery was fully charged and passed a load test, the next step was accessing the starter, where no signal/voltage to the starter motor solenoid was found. When the engine is cranked, there is power at the STS Fuse to indicate the ignition switch is working. The wires were traced to both starter cut relays, and starter cut relay 1 is mounted on the under-dash fuse box. Starter cut relay 1 closed in Park and neutral and powered Fuse 23 which tested good. The other relay, starter cut relay 2, is hard to see and needs the fuse box removed in order to access it because it is on a double relay holder mounted to the firewall. That relay was not closing when power and ground were applied to the relay coil, which indicated it was faulty.

The Solution:

Replacing the starter cut relay 2.

You can find this and over 3.5 million other confirmed fixes in Direct-Hit with a 14-day free trial. This week, our favorite fix is for a 2012 Buick Enclave whose exhaust smoked excessively following an oil change.

 

The Vehicle:

2012 Buick Enclave 3.6L (76k miles and well-serviced)

The Problem:

After having an oil change at a large local used car dealership, the customer complained about the engine smoking after starting the vehicle and a large amount of smoke came from the exhaust. The vehicle was sent for inspection and driven for a 2-mile test drive to confirm smoke from the exhaust (light blue and faint).

The Diagnosis:

After pulling the front PCV line off of the air inlet hose and valve cover for inspection, there was little or no draw on the tube through the engine. Oil was found inside after pulling the air inlet hose from the throttle body, and going to the rear PCV line showed a good vacuum from the intake manifold. Sticking a small drill bit into the PCV fitting in rear valve cover increased vacuum draw through the front PCV line. Sludge build-up was suspected, and removing the intake manifold to access the rear valve cover confirmed the PCV fitting was clogged and not allowing proper ventilation of crankcase leading to oil pushing in from the front valve cover.

The Solution:

Replaced the rear valve cover assembly and rechecked the vacuum draw on the front PCV line, which improved and released no smoke from the exhaust on a long test drive.

This week, our favorite fix is for a 2014 Nissan Versa whose engine would lose power or go into limp mode anytime the turn signals were operated.

 

The Vehicle:

2012 Jeep Patriot 4X4 2.4 Liter 4 Cylinder

The Problem:

The vehicle came in as a crank no start. Scanned the PCM and got the following trouble code: p0335 Crankshaft Position Sensor “A” Circuit Malfunction.

Other Applicable Vehicles:

2010 Chrysler Sebring, 2010-2014 Jeep Patriots

The Diagnosis:

I tested for spark and had none, and the fuel pressure was in spec. The P0335 code indicates no spark and a malfunction in the crankshaft position circuit.

The Solution:

Replace the crankshaft sensor.

Direct-Hit Fixes:

475 + crankshaft position sensors

Technicians Tip:

Be careful with the component location. It points to the sensor location, which appears to be underneath the fuel injectors, but it ended up being located underneath the exhaust manifold—which is very hard to locate on 4×4 models.

The Vehicle:

2014 Nissan Versa

The Problem:

The engine would lose power or go into limp mode anytime the left or right turn signals were operated.

Other Applicable Vehicles:

No DTCs or additional vehicles

The Diagnosis:

Checked all the exterior light operations and found improper turn signal operation on the front of the vehicle. Based on their behavior, it appeared the wrong style of bulbs were installed. After removing the bulbs, double filament bulbs were found to be installed in the front turn signal sockets where there should be single filament bulbs. It is suspected that the double filament bulbs falsely triggered the computer into thinking that the brake pedal

The Solution:

Installed the proper single filament bulbs in the front turn signals and tested the operation. The vehicle and turn signals operated properly without loss of power or limp mode.

The Problem:

The battery drains down overnight, and the alarm activates intermittently if the car is locked.

Other Applicable Vehicles:

No additional vehicles reported

The Diagnosis:

The car has keyless entry with a push button ignition. The ignition seems to turn itself on and will not shut off when pressing the button. I also noticed a clicking noise under the dash. We used Identifix to look up any information and found a similar post on the same vehicle. I followed the steps the other shop performed, and it led to a faulty Body Control Module (BCM).

You can find this and over 3.5 million other confirmed fixes in Direct-Hit with a 14-day free trial. This week, our favorite fix is for a 2017 Chevrolet Sonic with a check engine light but no drivability concerns.

 

The Vehicle:

2017 Chevrolet Sonic LS 1.8 Liter 4 Cylinder

The Problem:

The check engine light is on and there are no drivability concerns.

Diagnostic Trouble Codes (DTC’S):

P0498 Evaporative Emission (EVAP) Vent Solenoid Valve Control

Other Applicable Vehicles:

N/A

The Diagnosis:

With the circuit failure code, I first removed the vent solenoid and bench tested it with a power and ground to verify proper operation. While testing the wiring, I found that the power feed wire on the fuel tank harness passed a standard resistance test, but it failed a loaded test. After further investigation, I found that at the bend near the body the insulation on multiple wires was chaffed and the power feed had a pinhole in the chafe and was corroded.

The Solution:

I repaired the wire with a wire crimp and heat shrink to prevent future failure. I also re-wrapped the fuel tank jumper harness to help prevent water intrusion.

Bonus Tips

The Vent solenoid is a normally open solenoid so the P0442 code was a leak caused by the inability to properly close the system during a leak test before the P0498 code set.

The Fix of the Week: 

Every week, we review new fixes submitted by our Direct-Hit users and pick our favorite “Fix of The Week.” These fixes come directly from our customers and are told from their perspective. This week our favorite fix regards a 2015 Chevrolet Trax that’s blowing a lot of hot air.

 

The Vehicle:

2015 Chevrolet Trax LS 1.4 Liter 4 Cylinder

The Problem:

The air conditioning does not work and always blows warm air.

Diagnostic Trouble Codes (DTC’S):

None

Other Applicable Vehicles:

Chevy Trax 2013 and 2016.

The Diagnosis:

This vehicle has a manual cable control for mode and heat, so I hooked up the air conditioning gauges to check if it was a pressure issue. The pressures were normal for the day’s temperature and humidity, and the low-pressure line was cold which indicated normal AC operation. Because the heater blend door on this vehicle is manually controlled via cable, I removed the glove box to gain access and check its operation. The door could be moved by hand, and when doing so, the AC blew cold air. I removed the control knob assembly and found the cable had unspooled.

The Solution:

I reinstalled the cable and verified it worked correctly and smoothly without sticking or binding. Tip: When you are installing the cable, do not twist the cable in the retainer. If the cable gets spooled backward, hot will be cold and vice versa. See the illustration for reference below.

The Fix of the Week: 

Every week, we review new fixes submitted by our Direct-Hit users and pick our favorite “Fix of The Week.” This week our favorite fix regards a 2011 Chevy Malibu with a rattling noise and a Check Engine light, it comes to us directly from a technician in a shop based in Rochester, NY.

 

The Vehicle

2011 Chevrolet Malibu 2.4 Liter 4 Cylinder

The Problem:

There is a rattling noise and the Check Engine Light is on.

Diagnostic Trouble Codes (DTC’S):

P0106 Manifold Absolute Pressure (MAP) Sensor Performance and P0300 Random Multiple Misfires

Other Applicable Vehicles:

2010, 2011, and 2012 Chevy Malibu’s.

The Diagnosis:

I first checked the MAP sensor signal quickly and it checked out good. I noticed the rattling noise and knowing that these engines like to break the timing chain guides and wear the retaining bolts away, I pulled the oil filter and found a lot of metal shards. I pulled the valve cover and confirmed the missing front timing chain guide and worn away upper guide.

The Solution:

Replaced the Timing chain and guide kit, new (VVT) Variable Valve Timing Camshaft bolts, and oil and filter change.

Additional Information in Direct Hit:

There are 2 additional fixes for timing chain/ timing related repairs for the P0106 Code.
