I tried TrueCare for my 2008 Volvo AC problem after taking it to a couple of other repair shops in the area that couldn't determine the cause of the problem. The techs there performed a lot of testing of the usual suspects, compressor, condenser, etc. But they alone diagnosed the problem back to the ECM control unit, that a short of some kind within it. They manually bypassed the ECM and proved the compressor and all other components were fine and got it to blow cold air. Sadly, they do not service ECMs and recommended I replace it. I did my due diligence and found a Canadian company called XeMODeX where I sent my ECM to them for moving its configuration to a refurbished unit, $600, 24hr turn around. I was happy to see that XeMODeX verified a fault for the AC compressor. Received the module a week later as I used UPS ground not air, installed it myself and Voilà AC now working after 3 summers. Thank you TrueCare and XeMODeX.
