The alternator on my 2002 Pontiac Montana went bad and had to be replaced. While it was going bad, I lost the ability to unlock the doors with the armrest actuators, (switches) This is true for both the drivers and the passenger door switches. The locking function works fine as does the key fob control for both lock and unlock. Help

the manual covers that.
buy it ,or even the glove box guide, lost?

Replace the alternator, bad diodes in it allow the battery to discharge. Most all alternators now have built in regulators.

Answer:

It's in the owners manual under power door. I believe you pull the fuse under the hood for 15 sec with the overide switch in the off position. ...(roesterman adds...).My power door was opening all the way then closing immediately. I used this method to reset door and it worked! This started happening after I had some body work done to vehicle..maybe they disconnected battery or something. Delay locking was locking doors before slider was closing too. This left the door unlocked. I haven't tested to see if this has been corrected by reset yet.

sounds like a bad wire you may have to do a test back on that line to see if theres a bad connection.If you have a tester you can see if your getting power to the plug.

Most likely the window motor/regulator assembly has gone bad.Check for good fuse, if good pull out the switch and make sure you have power to it, if you do then remove door panel and test for power at motor, if u have power but motor won't work replace. Suggest replacing the regulator assembly as well because the cables often fray and cause problems as well.

I beleive you need to change the Power Window Switches Module in the drivers side door panel, as these connections are interlinked within this module and it is usually the first part that fails. Especially that you already changed the switches & motor in the passenger door and it still does not work. Once you remove the dual switch module in the driver's side door, you will understand what I mean. Plus it is really easy to access. Good luck! I have the same model, Claude

by the sounds of it the altanator is putting out enough voltage to keep the car running I my self don't think that it's the alt but the battery, if you don't know the age than it's not a bad idea to replace the battery. if the problem is still there than I would test the alt, should be putting out 14.6 volt at all times. but replace the battery first.

I can help with this problem, I just today had to remove my alternator on our 2003 Montana van. Here is how it is done, first disconnect the wiper motor wires and assembly then the two wiper rods (flat) needs to be loosened and disconnected, next comes the pipe cross member that when removed will also remove the complete wiper assembly. The bad thing is, after you do all this and the alternator is not the problem. Which in my case it wasn't. I hope this helps all who are having this problem.

your door lock actuators are bad.there electronic and are right costly

u r on ur child lock u deactivat ur child lock .
