Blower motor Transistor
 

Hi,

My blower fan runs at the highest setting all the time. Even when the car is shut off, I have to pull the fuse to stop it.

I've run an OBD code reader on it, nothing came up. I've also been searching the web for some answers with little luck. I don't know where to look, what I should be looking for...etc what should I do here?

Winter is soon approaching and I don't want to freeze!!!

Thanks

vvod, did you ever find a solution? I just encountered the same problem after burning out the blower motor and replacing it.

I ended up replacing the Relay and it went back to working normal.
It took me a few phone calls to various wreckers to find it but eventually got it for $40.

What year is your car?

I drive a '97 850 GLT wagon - guess I should update my signature, eh? :)
