I've got a hole-saw in the tool box just waiting for this to come around on my truck. (written tongue-in-cheek, but not really)

 

yeah, my air chisel will do a neat job!
then ill add a padlock!

 

Removing the master switch and waiting a few maybe even going inside for breakfast, lunch or dinner or even for the night then reconnecting it the next morning will always do the trick. It definitely does have to do with a voltage drop either because of a weak battery, a bad connection w/battery terminal or anything for that reason but doing as we have mentioned will always remedy the problem. Everything other than this will only be a waste of time. Been there and done it.

 

That's interesting, as I have never had to pop the master door switch to get mine, or the other couple dozen peeps I helped out, corrected. Just a lucky bunch of flukes I guess.

 

Hi guys,

Had this problem today. The solution was kind of weird, and this is certainly a more common problem than I thought.

Here is a video of the issue that I made to hopefully help some people out. I don't know if this is how all GMs work...but it certainly happens to a lot of hummers!

Hope this helps someone!

What you fixed was not the same problem this thread was started for (loss of correct voltage to the vehicle from the battery causing circuit glitch). Same end result symptom, yes, same cause, no.

However, still excellent information to have and will no doubt help others.

Thank you for posting. KUDOS!

 

I did run the battery dead and had to boost it that day (cleaning car and was playing music)

So it could have been caused by the same thing, but just reseating the rubber somehow worked for me

 

I had unplugged my battery to swap out my hvac bulbs (not sure if this was necessary but I did it anyway). I was happy to see my bulbs worked, but the next day I realized my drivers window only and power locks no longer worked. I'm so used to hear them lock in reverse or unlock when in park that I knew something was wrong. I found out about the window using a drive thru... that sucked. Anyways, I tried leaving the positive terminal off for 30 minutes and that didn't work, I also tried leaving the negative cable off for 30 minutes and that didn't work. On my 35 minute trek to work I turned the heater on full blast and aimed the leftmost one directly towards the master switch. When I got to work and put the truck in park I heard the sweetest sound of the doors unlocking! This was the first time this has ever happened to me and I've disconnected the battery many times. I'm guessing it has something to do with the cold? THANKS TO EVERY ONE WHO COMMENTED HERE!!!!!!

 

Popped the drivers door switches out carefully using a putty knife. Took apart the circuit board. Took me all of 3min to take it apart using toothpicks to separate the 6 hooks on each side of the switch housing. Touched a screwdriver to the capacitors **** on the underside of the board. (1/8" round about 1/2" long). Reassembled the switch, reconnected the wire clips, turned on the car and WALLA! The drivers door now works and the power locks function normally even with the remote key fob.


Thanks for the tips!

 

kHummer, what did you use to rejuvenate the rubber pad?
