I need an expert tech to help me.
My A/C was working very randomly so I took it into my local dealership.
They replaced the connector pin to the fan that runs after you shut the car off because it was burnt out under warranty.
When I picked my car up to go to my gym everything seemed to run fine. The streets I take have a LOT of stop lights, during heavy traffic, etc. My a/c started to blow warm air only at idle at basically every stoplight. Once I got the car going it would start blowing ice cold. It had a smell of "stagnant air" at idle.
Took it back to the dealership. The director of service drove my car home that night and he said it didn't act up on him once. I picked my car up the next day and at least I got a free car wash out of it. I accepted the answer that it worked for him EVEN THOUGH it wasn't working for me.
Couple of day passes (now today) and I'm driving my car in town and hit a few red lights and the a/c seemed to be working. I go through a drive-through and sit there for 2 minutes (at least) and sure enough my a/c blows warm. I live in Texas and right now it's 102º out. Take off away from the drive-through and it starts working again.
Below is a picture I took of my a/c display unit as it was blowing hot air.
Anybody have any ideas ?
