I've heard stories of this happening, but never would I have thought this would happen to me. My car was stored for a good 3 months. As with anybody, I would go out and run the car here and there over that time period and all was good. I trace this problem back to around the time a stereo was installed in my car, however, the problem didn't arise nor was noticed until I drove my car around the block and I went to park. Alas! I turn my car off and take key out and the blower motor wont shut off. I've been disconnecting the battery to kill it. I've looked online and have been hard pressed to find any actual solutions or resolved outcomes, just the typical "may be" scenarios.

Things I have done

- Replaced resistor - Needed to be done anyways.
- Checked control module
- Checked fuses

Here's my two questions

- Before I jump into the problem of messing with the motor or possible stuck relay further, is it possible that the radio has anything to do with the fan blowing on high nonstop? Perhaps a bad wire with the stereo harness? I'm guessing the ground wire. (I don't know electrical for crap, just making sure)

- What are the alternatives to temporarily resolve this issue? If I disconnect the resistor so I can drive, would that harm my car operating wise, if it's strictly for internal I can roll down the windows?

Thanks for any help guys!

 

I'd say from the schematic, pull fuse #36 ......

 

I agree, I was looking at diagrams as well, and that should kill it. As for the actual cause, It could be in the fan wiring, but most likely the controller itself.

 

Thanks guys. The fuse killed the climate control so i'll be alright for a while. I took apart the passenger side to get to the motor and will be tracing some wires tomorrow. Here's to finding something.

 

Back to your original question, I don't think that the radio could be the cause. At least not unless something was done wrong, or knocked loose.
