How can I pull the fuse for the rear wiper motor in 2007 Pontiac Torrent. It is draining the battery.

It's probably the washer pump motor , but testing is the best thing to do . Fuse #45 front an rear washer pump , plus there is two relay's . Both are controlled by the BCM - body control module . The fuse is located in the under hood fuse box .

In the under hood fuse box , should have diagram inside the lid . Front wiper's or rear ? Front fuse # 36 - 25 amp. Plus Two relay's PCB hi and Wiper PCB relay . Wouldn't think this being fuse problem . Wiper switch , motor etc... The wiper's are control by a computer . BCM - body control module .

The windshield wiper/washer system consists of front and rear wipers. The front and rear wipers are operative when the vehicle is in accessory or run. The front wipers have 4 different modes: Mist, Intermittent, Low, and High. When the front wipers are in the intermittent mode, there are 5 delay modes to chose from, commanded by the windshield wiper washer switch through the body control module (BCM). The rear wipers has an only one mode.

If the fuse is bad , could have a short to ground or wiper motor pulling to much current (amps) . Fuse's don't just blow for no reason ! Could also have DTC'S - diagnostic trouble codes stored in the BCM .

DTC B3715 02: Front Wiper Relay Drive Circuit Short to Ground
The body control module (BCM) controls the wiper motor based on input from the windshield wiper washer switch. The BCM monitors the wiper washer switch through three separate signal circuits and a ground circuit. The windshield wiper switch high signal circuit is used to determine high speed wiper operation, the windshield wiper switch low signal is used to determine low speed, intermittent, and mist operation through the use of a resistor ladder, and windshield washer switch signal circuit is used to determine washer operation.
The BCM controls the windshield wiper motor through two output controls, controlling two different PCB relays which control the desired wiper speed, high or low.

The PCB relay's are non- servicable , replace fuse box . Soldered in Your best bet mit be to take it to a qualified repair shop .

The motor is protected with a fuse and a circuit breaker. Check both to see if either need to be replaced. The fuse box is under the dash on the drivers side near the door. Open the box and look on the lid. You will find a list of all fuses, their amperage and what they protect. Remove the correct fuse by pulling it out with the plastic "fuse puller" that is stored in the fuse box cover. It looks similar to a short pair of tweezers.The fuse is burned out and needs to be replaced if the filament in the fuse is burned in half. If the fuse is good, you would next want to remove the wiper motor and use a volt meter to check for voltage between the wires that plug into the motor. Be sure to check for voltage with the wiper motor switch turned on. If you have power then you have bad motor, if you don't have power, you have an electrical problem.

The breaker should only turn off if the motor overheats due to something like the wiper being frozen to the window and not able to operate when you turn it on. This should reset once the wipers are turned off and the motor cools.

sometimes there are multiple fuses. If they are all good then the motor might be burned out, if not, then you have a ground somewhere but I doubt it.

Burned out motor

You probably have a poor electrical connection somewhere between the switch and the motor.

a small puller is best, but if you use a penetrating oil on the shaft, and a couple of screwdrivers (use rags underneath so you do not damage paint) you can walk it off the shaft.

Please check your altenator it has 6 diodes in it and it will still charge but will drain down your barttery overnight.I hope this helps you

its gotta be shorting out somewhere in the wireing

Check you ground you could have an exposed wire that is grounding out and draining the battery. This could be a BIG fire hazard.
