I've searched high and low and have yet to find a solution to my major problem.

The A/C first started blowing less than adequate cold air, then started to blow warm air. I tried to recharge the A/C - no luck.
The A/C started to blow hot air out of the drivers vent and cold air out of the passengers vent.
All within a week the above happened and now the A/C only blows heat out of the defroster vents.

I took the truck into an auto electric repair shop. The following codes are are being thrown:
B0229 Recirculate Position Feedback Circuit Range/Performance
B0263 Air Flow Control 6 A/C Circuit
B0414 Temperature Control 1 Feedback Circuit Range/Performance
B0424 Temperature Control 2 Feedback Circuit Range/Performance
B0418 Temperature Control 2 Circuit
B2355 Driver Seat Front Vertical Position Sensor Circuit
B2365 Driver Seat Rear Vertical Position Sensor Circuit

 

I bet there is a blend door motor going out.

 

yup. not cheap
