My '06 Pt Cruiser A/C works fine @ speed, but idling and @ stop lights it blows moist warmish air and idles roughly. Does anyone else have this problem? ---

Clean the IAC and that should raise the idle. Are the plugs and wires are good? Also, maybe the R134A refrigerant is low, but first I would start with fixing the rough idle. ---

Inspect the radiator/condenser fan operation. The fan motor or relay may have failed. ---

I’ll check out IAC and relays, I hope fan does not need replacing. Some web sites seem to suggest fan drawing too much power is problem. ---

I’d also make sure there is no crud blocking up the condenser coil in front of the radiator. A strong garden hose spray can flush out dirt, leaves, and debris. ---

Fans are electric and will not slow engine. Here is a schematic of the fan.[https://www.google.com/?gws\_rd=ssl#q=fans+on+2006+pt+cruiser&facrc=\_&imgrc=\_5B92waqdtDzMM%3A%3Bundefined%3Bhttp%3A%2F%2Fww2.justanswer.com%2Fuploads%2Fquadrin7891%2F2011-06-09\_031221\_pt\_fan.gif%3Bhttp%3A%2F%2Fwww.justanswer.com%2Fchrysler%2F52b68-cooling-fan-will-not-engage-when-a-c-turned.html%3B640%3B840](https://www.google.com/?gws_rd=ssl#q=fans+on+2006+pt+cruiser&facrc=_&imgrc=_5B92waqdtDzMM%253A%3Bundefined%3Bhttp%253A%252F%252Fww2.justanswer.com%252Fuploads%252Fquadrin7891%252F2011-06-09_031221_pt_fan.gif%3Bhttp%253A%252F%252Fwww.justanswer.com%252Fchrysler%252F52b68-cooling-fan-will-not-engage-when-a-c-turned.html%3B640%3B840) ---

I cleaned the IAC with MAF cleaner and replaced wires and plugs, 95% success, idles normally 95% of the time. Ordered new IAC suspect old one failing as it worked well after cleaning, but still falters at times. ---
