Question about 2000 Pontiac Montana

Montana with windshield wiper issues

I have the same problem as the others. How can you tell if your cam assembly is broken? Can you just grease it? Where exactly is the cam assembly? Is is near the wiper motor?

2003 Pontiac Montana wipers not working how to fix


First you need a wiring diagram, free at http://www.bbbind.com/free_tsb.html Then you need a DVOM - digital volt ohm meter to test the circuit . Then if your not familiar with automotive electrical systems testing ,go on youtube an check out Electric Testing Techniques You Need to Know Also having a factory diagnostic trouble shooting chart would also be usefull . You could just start replacing parts , you mite get lucky . The wiper motor is a high fail part , so is the switch ..You could find the fuse is blown ! But fuse's don't usually blow without a reason . Short to ground , low resistance . ( high current flow) Also knowing how they work and what all is involved in making them work.
The Wiper/Washer System consists of the following components:
• Windshield wiper/washer switch
• Windshield wiper motor module
• Windshield wiper motor
• Windshield washer pump motor
• FRT/WPR/WSHR 25A fuse

Wiper/Washer System Operation
The windshield wiper motor module is part of the windshield wiper motor cover and controls wiper motor operation. The windshield wiper motor is a 2 speed motor and is operated at low speed in all modes except HIGH. The accessory voltage supply circuit to the windshield wiper motor assembly is used to operate the wiper motor in all of the low speed modes. The accessory voltage supply circuit to the windshield wiper/washer switch is used to supply the windshield wiper switch signal circuits and the wiper motor high speed circuit.
When the wiper/washer switch is in the LOW position voltage is supplied through a 24K ohm resistor within the switch to the windshield wiper switch signal 2 circuit, and accessory voltage is supplied to the windshield wiper switch signal 1 circuit. The reduced voltage from the wiper switch signal 2 circuit and accessory voltage from the wiper switch signal 1 circuit causes the wiper motor module to close the wiper motor accessory voltage supply circuit to the wiper motor low speed terminal.
Windshield wiper/washer system MIST operation is identical to LOW operation except that the MIST switch is a press and release type. When the wiper switch is moved to the MIST position and released, low speed wiper motor operation is started and will continue until 1 cycle is complete. If the wiper switch is moved to the MIST position and held, the windshield wiper motor will operate in the LOW mode until the switch is released.

Don't the wipers work in any mode ?

Connect a test lamp from the accessory voltage circuit of the windshield wiper motor to a good ground.
Does the test lamp illuminate?
YES - Go to Step 4
NO - Go to Step 13

Connect a test lamp from the accessory voltage circuit to the ground circuit of the windshield wiper motor.
Does the test lamp illuminate?
YES - Go to Step 5
NO - Go to Step 14

My windshield wipers just up and quit. They pulse every few seconds trying to come on. What would the problem be?


This can be due to slippage or looseness in the wiper arm fittings or the wiper motor spiral wheel assembly If there is noise when the wipers are put on , then pull up the wipers from the glass and see if they work. If so the nurlings are worn out and a metal shim on the nurlings which can be tightened can solve the issue

Need to know how to install the RH wiper linkage in a Nissan 200SX. I know how to remove the wiper arms and plastic cover below the windshield. Just need to know how to install the linkage with out...


The wiper cam actuator the cam is made to prevent damage to the motor by using a spring to allow it to slip if the wipers are stuck or frozen to the wind shield the spring stretching causes the wipers to stop in the middle of the window not hard to replace but does require you to do a timing procedure it should come in the box if not ill give you the basics get the new part remove both wiper arms careful the windshield is under the black plastic and I've seen other break the windshield taking the wiper arms off a battery post puller is the best way to remove , remove the cowl plastic piece you will see the cam gold/silver in color remove the one torx head screw then install new one rotate clockwise 2 times should spin freely then spin counter clockwise should stop look at where it is touching this area should have a 4mm gap the wiper motor has to be in the intermittent position prior to this turn key on put wipers in intermittent let motor spin then when it stops shut the key off then install cam.

Connect the electrical connector to the wiper motor.Connect the RH linkage assembly to the wiper motor with the J 39529 .
Important: When installing the wiper motor, be sure that the crank arm is in the innerwipe position. The crank arm drive pin must be engaged in the cam pocket.
Install the wiper motor with two locator pads pressed into the slots of the bracket.
Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

Timing off on Pontiac Montana wipers


On top of the window motor there is a timing cam -- there is a little tab on the bottom that is most likely broken or bent. You need to replace the cam.

Windshield wipers stopped working on 1998 Nissan Sentra. Is it a fuse problem? If so, where is fuse box and which fuse? Is it a motor problem? is this an easy diy fix?


Water can enter and displace the grease in the wiper arm linkage ball joint where the wiper linkage attaches to the wiper motor linkage.

This can result in gradual wear over a period of time inside the joint that could lead to the separation of the wiper linkage assembly from the wiper motor linkage at the ball joint. A loss of windshield wiper function can result when this separation occurs.

To prevent grease from being washed out of the joint, the dealers will modify by adding a water diversion seal that will prevent water from entering the windshield wiper linkage ball joint area.

2001 Pontiac montanaThe front wipers park in the up position


This is a common problem with Chevy Venture, Olds Silhouette, and  Pontiac Montana. The mechanical wiper drive and parking cam assembly, if it's not broken, needs adjustment. The spring loaded stop arm should engage the vertical tab on the assembly mounting plate when the wiper motor reverses. See pic.  9a7b0af.jpg
I will upload the instructions to fix this problem, if there is interest.

2000 pontiac montana wipers stuck


This has happened a couple of times on my 1999 Pontiac Montana. Here's what I did to fix. Open the hood. Remove the shield over the the wiper cam mechanism on the passengers side. This is easy to access. Road salts and other dust and dirt gets in there and causes the sticking problem. Spray WD-40 in between the parts. Get in there with that little red spray straw and saturate it good, flush junk out. Get in the car and try the wipers. If I remember, you might have to manually place that little knob or lever on top of the cam in the opposite position to get it to resync, but try it first. Be sure the wipers are off when you're spraying the WD-40 so you don't injur your hands. I've had to do this twice and it worked both times.

Windshield wipers


The problem is the cam assembly that sits on the motor shaft. It gets torqued out of position by snow or ice. When the motor reverses to park, the cam assembly should open as it is reversing, ( pin registering in top plate) and revolve with that pin being 180 degrees opposite of the slot it slides in when the wipers are wiping. On the bottom of the 3 plates, there is a spring loaded arm that will contact a stop, thus parking the wipers. One torx head screw holds the cam on; remove it; run the motor through a few cycles; hand park the wipers, reassemble with that top pin opposite of it's slot for normal operation. A small screwdriver can move the pin out of it's slot, and then you can rotate the plates to move it to position. I've had the best luck with the arm on the bottom just past its stop.
