My 2009 Volvo XC90 R-Design AWD 3.2L went to the body shop for body repair. A replacement passenger mirror (used) was installed and now the a/c is not blowing cold air. There is an error code showing on the rpm dash gauge which is several dash lines positioned beside the P (in parked mode). Example: P ==/== There also a orange triangle with exclamation mark which is illuminated.
The shop manager put a computer diagnosis reader on the car. Two codes were showing: 1 Climate Control Module - 0040 Air quality sensor internal fault ...and 2 Power Seat Module - 001C Control panel signal missing.
I'm looking for help to determine the problem. The shop is not assuming responsibility and the car was left at the body shop because the body repairs have caused the a/c to blow hot air. Checking under the hood, the a/c coolant lines have minimal coolness to the touch by hand. Suggestions will be appreciated. Thanks

 

An xc90 of that vintage has a temp sensor in the outside mirrors. Those are used to tell the Engine management system and the climate system what the temp is outside. One possibility is the climate system won't blow cold if it thinks it's too cold outside. (I'm thinking it's the one that was just installed if ac was cold before and that was the only thing done) Either a poor connection or bad sensor - you could swap the old sensor from your old mirror if still available. (if the replacement one is sending the wrong signal) With a compatible scan tool you can see what that sensor is telling the ECU.

What's your outside air temp gauge on the dash showing? I suspect it's your /== indication you reported. Did the body shop provide and sell you the mirror? If so they would be responsible for not selling you a good used part. If you sourced the mirror yourself and gave it to them to install - the bad sensor is on you. (unless they did not plug it in properly - but that will be hard to prove)

 

Thanks for your response. This used passenger mirror was ordered by the body shop. I appreciate the comments. Thanks
