Question, I bought a 2010 gmc Acadia few months ago. I notice the a.c. would get warmer as I am on idle. So I took the Acadia to a mechanic and they said the a.c. line had no Freon but high pressure then added Freon. A month later same problem, took it to another mechanic and same problem. This time they check to see if the vehicle had a leak and couldnt find nothing. A month later I took it to the dealer and they said it had a line leaking and needed rear evaporator. I got the inspection and took it to the dealer where I bought it and they offer to fix it. After having the vehicle for 3 weeks they said they couldnt find no leak or issues with the a.c. Has anyone had this problem before ? what should I do ?
Mike Morava: when youre at idle your a/c depends more on the Fan for airflow through your evaporator, when you are going down the road you gwt airflow from that as well.. I would make sure your fans are good, one may not be kicking on when you turn your a/c on like its supposed too.. check relays/fuses etc..
Bryan Ruigrok: Work at a dealer rear AC lines leak due to corrosion and have found pin holes in lines hidden by plastic sheathing. Do they inject system with UV dye ?
