I got a leak from my ac fixed and it was fine and a couple days later it started blowing out warm, but then got back cold after a while. Then I notice the temperature on my dashboard kept switching.

Asked by Apr 08, 2015 at 12:46 PM about the 2006 Pontiac Grand Prix GT

Question type: Maintenance & Repair

For example it would read 73 degrees
and it would blow out cold then it would
switch to 14 degrees and it blows warm. I
took it to the mechanic he said it was the
temperature sensor so I got that and he
put it on but it's still doing the same
thing. The temperature changes back
and forth. So what is the problem now?

I was going to say the temp sensor myself, so I'd check the wiring or connections.

Sounds like it's switching from Fahrenheit to Celsius. I assume that you're referring to the set temp and not the outside temp? Most likely the climate control head is bad. HTH. -Jim
