Bruce Nunnally Posted June 26, 2012 Report Share Posted June 26, 2012 Welcome to CaddyInfo! I would guess Low refriferant and / or mixing door stuck. Can you post the DTC codes?

gordycakes Posted June 26, 2012 Author Report Share Posted June 26, 2012 How can I decode them Link to comment Share on other sites More sharing options...
Bruce Nunnally Posted June 26, 2012 Report Share Posted June 26, 2012 Generally check a list of codes like this one http://www.caddyinfo.com/dtc_1999.htm. Then consult the shop manual for how to diagnose each one. Most of the B0xx codes you have, where the xx means 17 or 26 or 51 are all related to an airbag deployment. For a/c the codes of interest would be codes like B131x to B134x which I don't see in your list oddly enough Bruce 2023 Cadillac CT4-V Blackwing Follow me on: Twitter Instagram Youtube Link to comment Share on other sites More sharing options...
cdgrinci Posted June 26, 2012 Report Share Posted June 26, 2012 The problem you describe is, as Bruce mentioned earlier, classic 'low refrigerant'; warm air from drivers side, cool(er) air from passenger side. If you wait long enough (without fixing/recharging) your passenger side will also begin to get warmer. The quickest, non diagnostic, thing to try is, to just try adding a can of refrigerant (but it does sound as you have a leak). For less than 20 bucks you can probably get your a/c back online; how long it lasts, will depend if your leak is very slow or more aggressive.

rockfangd Posted June 27, 2012 Report Share Posted June 27, 2012 just out of curiosity have the airbags been deployed on the car? Also agree on telltale low refrigerant. the evaperator is closest to the passenger side so it is the coldest. Am curious on the fuse problem. Wonder if the low refrigerant could be blowing the fuse GM FAN FOREVER Nice, clean, luxury= fine automobile Link to comment Share on other sites More sharing options...
KHE Posted June 27, 2012 Report Share Posted June 27, 2012 It is normal for a 12 year old car to need a boost of refrigerant. Use plain R-134a - no additives or extra cooling agents are needed. The fact the driver's side is hot and the passenger side is cool without setting a low refrigerant code is a textbook case of low refrigerant on the multi-zone climate control systems. The issue with the rear is most likely the actuator as it is setting code B0429.
