My van's AC was working fine and it was really cold. But one day and I left the van/air running until I ran into the store and when I came back out it was blowing hot, and has been blowing hot ever since. Does anyone know what might have caused this?

Good morning.

Do you know if the compressor is engaged?

I would start by having the Freon checked as you may have a leak.

I am not sure what the compressor is, I really do not know anything about vehicles.

Okay, then I would take it to a shop and have them check it for you. It could be a lot of different possibilities.

It may be something simple or it may be more involved but someone needs to look at it for you and give you an estimate.

Once you find out the issue, report back to us with there estimate and we can go over it with you.

Good morning,

The first thing that needs to be done is have the Freon checked. If it is too low, the compressor will not come on.

I attached a wiring diagram for you to view. You need to test for power to the clutch relay to see if there is power for the compressor.
