[quote="billofdurham"]Have you checked for fault codes? Your car has the On Board Diagnostic unit in the engine compartment. No code reader needed.

I have to apply a lot of pressure on the brake pedal to make it stop within a reasonable distance. I have taken the car to two different national ...

I have a '96 850 and heater/ac 4 speed fan only works on the high speed. I changed out the fan resistor network (no fun !) but the fan still only runs on high speed. I checked the fused and it seems unlikely that it's the switch. Anyone else seen this problem and have a suggestion what I should chec...
