I have a 99 cougar it pulls to the left when you hit the brakes i have changed the brakes and put new wheel bearings on it but it still pulls can somebody help.I also have a problem with the driver side power window not woorking new motor not getting power.

 

with the brakes, you may have to bleed the brakes and get the alignment checked. with the window motor, that's just a trace the wiring until you find what's busted. First check is if the motor is plugged in. While you have to door opened up and can see the motor, try it and check to see if it's moving and just not moving the regulator. If so, there may be a problem with the regulator and/or the mechanics of the motor. make sure the wires to the switches are in good shape and connected and such. Also check the switches on the driver door. Make sure the wires are all connected on the driver door as well.
