Every other time I start my car

Recommended Posts

In the last week, every other time I start my car, the AC goes crazy. It thinks it's like 20degrees warmer than normal. If I shut it off and restart it, it goes back to normal. It's every other time, not when it's hot or not. If it's fine when I get to work, then it's wrong when I head to lunch, etc...

What the... ??

All I can recommend is to disconnect the battery Friday night (if this is a dd), let it sit overnight, then drive it over the weekend. This hopefully will let the computers relearn. I don't know, but it's worth a try, I think.

I would suspect one of three things:

Your passenger compartment fan/sensor is clogged or malfunctioning. You can remove it from the small compartment behind the circular looking grill looking thing on the right side of the dash in front of the passenger seat. Then try to clean it.

Your outside temperature sensor is malfunctioning. Sometimes they just need to be replaced.

The A/C control panel is malfunctioning. There have been reports of these going haywire, and many times replacement is the only cure.
