Fix Of The Week – May 12th 2020
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.
2015 Chevrolet Trax LS 1.4 Liter 4 Cylinder
The air conditioning does not work and always blows warm air.
Diagnostic Trouble Codes (DTC’S):
Other Applicable Vehicles:
Chevy Trax 2013 and 2016.
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.
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.
