How to fix a motor oil leak in a Pontiac Montana 1999

I went to bulldogsecurity.com and looked up the wiring diagram for this vehcle. However, prior to checking this part, I would check to see if you have a blown fuse. It doesn't hurt and only takes a few minutes. There should be a fuse for that either somewhere on the side of the dash or near the brake pedal area. If not it may be under the hood, but it should be inside the vehicle. You may have multiple fuse boxes. If it has (2) sliding doors it will have a wire for the auto doors in each kick panel (under the plastic trim/molding) when you open the door and look down you will see all of the trim/molding it should snap out or may be held in place with a screw or (2). Once you remove that you should see the wires. It says for the left side it is either light blue or black and the right side is definitely light blue. Trace this wire until you find out where it ends (the motor or switch to control the auto doors) Then test the switch/motor to see if it is bad.

Remove the wheel, remove the hub nut, remove the brake caliper and rotor, put your socket and extension through the hub flange onto the bearing retainer bolts, undo them, release the abs sensor connector if it has it, remove the bearing and hub flange as an assembly, put the new one on and go backwards from here. Torque the hub nut to 180 ft/lbs, your done.

Yes, it can be removed and run without the thermostat. However, your gas mileage will suffer and the heater may not work very well.

Bet the drain is clogged with leaves. Look under the blower motor under the hood. Can almost be that the cowling has been filled with leaves at one time or another. Got to clean that stuff out every now and then.
