Hi- where could be the problem ?After i stop the engine the blower motor is still working on high speed.I have to take the fuse out to stop it. Also the cold air is not coming anymore with the blower ,only when the blower is stoped at 0 and some cold air is coming at high speed on the highway.

Don't take out the fuse. The blower motor is designed to run after you turn off the motor. It is drying out the condenser so that you don't have mold build up in the AC system. It is perfectly normal.

How long did the blower kept on blowing, after shutting off the ignition?


BTW, i have moved this to the 850 Forum.
Thanks.

More than 3 hours ,i have to take the fuse out so i still have a working batery.

Something shorted out in the wiring.

I just take the car to Volvo,is the bolwer resistor :) . Is gonna cost me 36o$ :blush: to replace it over there. So far i just keep taking out the fuse when i stop for a long time. I have to find out what tipe of resistor i need because there is 2 tipes for that car.
Anybody know where is installed this resistor ,how many wires are going in?

It is located in the front of the air box.Next to where the blower motor is located.

If I remember correctly it is like 4 to 6 wires going to it.
