Help! Seat HVAC

[6444johnf]

I'm in need of guidance on troubleshooting the seat heat / cooling system. My understanding is the only moving part is the fan so this should be easy.

Fuse 42 is the drivers side. Fuse 41 is the Passenger side.

The fuse block is under the carpet in the passenger side footwell.

Good place to start.

If the front bolster between your leg does cool down, it's working and won't be the fuse.

The XLR doesn't blow air out of the seat as well as newer models do though. I sat in a 2013 Avalanche with heated/cooled seats and you could really feel the cool air coming out of the perforations. Not so much on the XLR.

Fans tend to go bad.

Your post didn't indicate if your problem is confined to one or both seats. If it's both, start with the HVAC unit. If just one, slide the seat forward, push the seatback forward and inspect the ducts for tears or disconnects. If those are good, place the cooling mode to MAX and disconnect the duct. Ensure the fan is blowing cold air. If the fan is blowing, but the air isn't cold, the heat/cool module is suspect. If no air is felt, the fan and HVAC are suspect.

A lot of problems are caused by disconnected ducts, so this is the obvious first step to begin troubleshooting when a single seat is having issues. When I first bought my car, both seats had torn/disconnected air ducts.

I replaced drivers side fan last year, about $65 and couple of hours if you do it yourself. Most of that is taking out and reinstalling the seat.

I'm having a hard time finding the correct part numbers for this system. Once I take the seats out I want to replace everything at one time!

Your original post was over a year ago, when you thought there was an easy fix involved for a problem that was never adequately described.

Defining the symptoms of your problem, the parts needed, and seat side(s) you wish to replace them on would make it easier to help you.

Asking for part numbers to replace "everything" is a little vague.

2009 XLR V Shocks

Please don't thread-jack this thread. You should start a new thread, (There's a button for this.) and post your (unrelated) questions there under the appropriate title so it's easier for someone to find later. Otherwise the answer gets buried in another thread and any searches for information on a topic are harder to find.

Thanks,

CC

Pardon me CCClarke,

When I move through the various parts vendors there appears not to be a specific part number for the module, fan, filter or hose. Yes I have been quite busy so now that I have two spare minuets I want to remove both seats and completely replace the seat heater / coolers. I would much rather have spare parts on my shelves that to wait, with the car taken apart, for the unanticipated failed part.
