I believe that the solenoids for my door locks are dying. The drives side is weak, and sometimes I need to use the key to unlock the door. And today the rear passenger door will not unlock electronically.

Anyone change them here? Wondering what kind of job it is. Thanks

 

You have to replace the entire lock mechanism. That is fairly expensive.

You might be able to patch in a generic solenoid if you can figure an attachment spot. They are really cheap, I did that on all 4 on my Mazda. I just mounted the solenoid and attached it to the wire rod then spliced into the wiring. That left the original hooked up so the new one is acting like a helper rather than replacement.

Lee- How is the battery in your Fob ?

 

Battery is fine. If it was low, then none of the doors would unlock. Most of the time the doors work. So the motor is getting weak.

 

Thanks for the info and advice. The locks usually all work. And when the drivers side doesnt, GM was thoughtful enough to have a key hole there.

 

How long do you expect grease to hang around?

 

Well, if the grease is someplace I don't want it it's there forever.

But yeah, Lee should lube and check for free movement before throwing solenoids in there. (Which is what you were aiming at, I believe)

 

It may be sticking. Sometimes I have to press the fob a few times for the lock to fully go down or up Do you think if I spray down the button it will get the linkage, or do I need to pull he door panel off

 

You'll have to pull the panel to do it right...

 

My driver door lock started doing the EXACT same thing last week. I have to hit the key fob twice to get it to fully unlock. The other doors all work fine.
