My 2008 is causing me grief.
I can turn the heater fan off, turn all the other dials to the cool settings, but it still pumps out hot air by our feet.
This is a real pain in the summer...lol
Is this a thermostat problem? Wiring? Circuits?

The a/c works fine, and I'm pretty sure that it stops blowing out hot air once the a/c is turned on, but not 100% sure on that.
Anyone else have this problem?
Any solutions? Don't want to pay a high price for something I can fix myself.

Is the van still under warranty?

 

This issue sometimes happens as these vans hvac is all electronic.. Usually a flash will solve this issue as it did on my 2008 when i still had it. You will need to take it in and get diagnosed as it could be several things happening.
