Automatic Climate Control 850 1994



Looking for help on my 94' 850 wagon. I have recently overhauled the blower motor. Now the blower motor will not come on while the car is running in either AUT mode or manual fan speed selection. If you shut the car off and only advance the ignition to accessories and not start the car, the fan will run all day! Then you go and start the car and the fan will come on for about 1 second and then stop. Any suggestions on how to cure this as the winter is setting in up in Canada! I do not have any wiring diagrams for the ACC. Thanks.

Re: Automatic Climate Control 850 1994

Had the same problem with my 94 850 turbo... the day I bought it used from the dealer... in the middle of Summer. After some fussing, which probably wasn't necessary, the Volvo dealer replaced the resistor pack and it has been wonderful, ever since.

By the way, mine run intermittantly, even during the initial test drive, and then just died a few hours after I picked the car up.

I LOVE the car, otherwise!

Good Luck!

Shawn
