Confirmed Fix:
Replaced Catalytic Converter(s)
 
Problem Description:
Trouble code P1273 bank 1 lean. Using a scan tool, looked at the O2 sensor readings and the bank 1 O2 sensor was biased lean. Smoke tested the engine and found no leaks. Tried a propane enrichment and there were no changes in the readings. Raised the vehicle, and using light pressure pulled down on the bank 1 catalytic converter heat shield and found 2 of the shield welds had broken and left 2 small holes in the converter. Replaced the bank 1 catalytic converter and cleared the code. Vehicle is fixed.

Confirmed Fix:
Replaced Air Conditioner (A/C) Evaporator Temperature Sensor
 
Problem Description:
The A/C compressor cycled rapidly even with a full freon charge. A scan test of the HVAC control had a trouble code for the Evap Temp Sensor. Replaced the Evap Temp Sensor located in the evaporator case and proper operation of the A/C compressor returned. The sensor is located in the evaporator case beside the gas pedal and BEHIND the air duct. The air duct does not come out, so you have to work behind it with a mirror and a long skinny screwdriver.

Confirmed Fix:
Replaced Power Window Circuit Breaker
 
Problem Description:
All of the power windows stopped working from all switches. No trouble codes present. Could hear a clicking sound from behind the glove box when the window would stop, and would hear it right before they would begin working again.
Lowered the glove box and found the 25 amp circuit breaker for the windows (there are 3). The one for the power windows is all the way to the right). It was tripping and extremely hot. Removed and replaced it with one of the others and the windows worked perfectly and the circuit breaker never got hot. If shaken, it sounded like something had come loose inside. Replaced the 25 amp power window circuit breaker with a new one and the problem has been fixed.

Confirmed Fix:
Programmed Powertrain Control Module (PCM)
 
Problem Description:
After a maintainance reflash of the PCM and FCM, trouble code P0461 appeared. This code was not there before the reflash. The PCM was seeing the vehicle rolling at 8 miles per second on the odometer inside the PCM, not the actual odometer. The PCM looks for a change in fuel level after a certain mileage has passed. When it did not see it it threw the P0461 code in 117 seconds after clearing it. We used a StarMobile with Witech software to install the current mileage from the dash into the PCM and the problem was gone. I think a SnapOn scanner will do the same thing. This normally only has to be done when a new PCM is installed. Both odometers read the same now and no Check Engine Light (CEL) is on.

Confirmed Fix:
Replaced Rear Differential Tone Ring and Replaced Differential Carrier Assembly
 
Problem Description:
False ABS activation during slow stops, usually around 10 MPH and below. 2WD vehicle with 4-wheel ABS. No ABS codes. Observe scan data while braking and experiencing symptom; front wheel speed sensors reading exactly the same while the rear speed sensor is slightly hashy. Suspected a rear wheel speed sensor; remove and inspect. Rotate the rear gear at least one complete revolution. Had 1/2 of one tooth on the tone ring missing; part of the differential was coming apart and jamming up in the ABS tone ring. Replaced the defective carrier and installed a new tone ring. Retest system; no more hash on the rear speed sensor signal and no false modulation. Good to go.

Parts replaced: Differential carrier and rear ABS tone ring.
