The rear wiper on a 1998 Pontiac Montana may not stop due to a faulty wiper relay, a malfunctioning wiper motor, or a short circuit in the wiring. Additionally, a stuck wiper switch can also keep the wiper activated. Inspecting the wiring and testing the relay and motor can help identify the issue. If needed, replacing the faulty component should resolve the problem.
To replace a wiper blade on a Pontiac Montana, start by lifting the wiper arm away from the windshield. Locate the release tab on the old wiper blade, press it, and slide the blade off the arm. Align the new wiper blade with the arm, ensuring it clicks into place securely. Finally, lower the wiper arm back onto the windshield and repeat the process for the other side if necessary.
If one wiper on your 2002 Pontiac Montana works while the other does not, it could be due to a few common issues. The most likely causes are a burned-out wiper motor for the non-functioning side, a broken or disconnected linkage, or a problem with the wiper arm itself, such as a loose connection. Additionally, a blown fuse or a malfunctioning switch could also be contributing to the issue. Inspecting these components should help identify the specific problem.
It's the same resevoir. The hose may be clogged or sediment in the bottom of the resevoir. See if the front still work and hope for the best. The motor for the back might not be working. GOOD LUCK
It is definitely a pin inside the wiper motor that is worn out. I just had mine replaced in my 02 Montana. The pin can be seen by removing the cover from the motor.
