AC shut off

It has been a great summer with my 2004 c5. However, when I shut the driver's door my AC turns off. Otherwise, it stays on while driving. Does anyone know what causes this? I will pull codes as soon as possible.

I have noticed mine do that as well, car and air running, get out and close door and air shuts off. I bet it is some sort f feature to prevent something. Look forward to response

That's a relief. Thanks for the response. Has anyone else noticed the AC shut off?

I'm getting, 99 hvac b0367 h code. GM part #89018365 seems the solution.

Nice save! I followed the link, followed the instructions, and now the AC stays on. Thanks a million.

I find it hard to believe recalibrating the actuators is keeping the HVAC unit from shutting all A/C off when you close the door.

Well, it is true. Tested on two separate drives. When the fuse was pulled and put back in, the corvette went through a series of resets on the dic. Tire pressure was unknown for the beginning of the first test and the AC went though a series of auto states. At first I thought I had made the situation worse, but everything returned to normal. I will report back if anything changes.

Thanks. That is very strange. I can't figure out the connection.

Well the code is back, but the AC works when using the door. When I clear the code, the vent auto adjust. I'm stumped by the odd behavior.

A/C settings are part of the seat memory, right? Bad connection at the door making it switch to one of the other two configurations?

I don't think so but i am not a guru but find it hard to think ac and seat memory are related. I had my ac shut off when i opened and closed door twice but haven't tried it lately. It hasn't bugged me to the point of chasing it down. Will b following this
