A few days ago, my 2004 crossfire would not start due to a dead battery. It jumped right off and ran fine. Same thing the next day. I noticed that the recirculation fan continued to run and was draining the battery. The only way I can get it to turn off is to remove the fuse. Once I put the fuse back in, it immediately turns the fan on. I know the fan can run for a short amount of time even with the car turned off, but my fan continue to run unless fuse is removed.

Thanks in advance!

 

The recirculation fan?

 

I think he means the recirculation fan button that you push that keeps the blower fan blowing while the car is off. Its useful for winter if you're making a short stop somewhere or getting gas as it keeps blowing residual heat into the cabin.

OP I think your hvac controls might be going bad. Ive had it happen to me once and it would cause erratic blower speed. I bought a used one off ebay and swap it and my problem was fixed.
