Hello,
Yesterday I was driving home from work, about a 20 minute drive, woth the a/c of full blast and right before I got home it started blowing hot air. Does anyone know what caused this?

Thanks,
Tom

 

There is a cycle switch that wears out and its very common. Real easy to replace. The part is like $11.

 

Cool thanks for the info. I'll order a new one this week. Where is this cycle swtich located?

Thanks,
Tom

 

Look at the aluminum lines goin to the accumalator. You will see something that looks like a sensor with 2 wires goin to it. Unplug the switch and use a wrench to loosen the switch. It has a little pressure but nothin will blow up or pop.
