Repair Questions and Answers
Question:
2000 GM Pontiac Montana 3.4 mileage: 75,000. Hello,
Our question is: I am having a problem with my
Montana's door locks. When I press the on lock
button to exit the vehicle it automatically locks.
Also when I try to enter the vehicle with the key once
it unlocks and I remove the key it automatically locks
up again before the door can be opened. When
we are driving, the locks are continuously locking and
unlocking on their own without our contact. We
have contacted the dealer for the fourth time and they
can't seem to locate the problem. Please note that
this vehicle doesn't have a remote door opener.
Please advise.
Answer:
If an aftermarket alarm system has been installed on
your car, this may be the source of your problems.
If not, the body control module may be faulty.
