Good link for the clip repair.
My problem is related but different. I believe the rear window actuator is fried on my '98 Blazer. I had to remove the fuse to keep the actuator from continually operating. The rear window would pop open while driving or while parked without a button or keyfob being pushed! Can anyone confirm or advise? Where does one get a rear window actuator? I think I read somewhere that the door lock actuator and rear window actuator are the same part number?
Thanks in advance!

Sounds more like the tailgate window switch is shorting, causing the solenoid to fire. Typical failure mode on a solenoid is to not operate. Seems somewhere in this forum mention was made of dirt getting into the tailgate switch and not letting it fully release, causing intermittent window release. Then again, it could just be the voices in my head trying to confuse me...

Thanks for your insight, Jeff. Sounds logical that it's the switch...only problem is, where is the switch? Is this the key fob button, the dash board button or is it in the release/latch mechanism in the rear door? Are you able to describe what it looks like?
Thanks again!

Do you have the tailgate (flips down) or the lift gate (whole door goes up)?

Like most I have the lift gate, sort of like a hatchback design.

The switch is in the hatch and is activated by the pushbutton below the window. One trick is to push the button in all the way and use a shop vac or air source to make sure there isn't dirt that is keeping the button from fully releasing, thereby activating the switch intermittently.

Thanks! I'll check this out today and let you know. When I think back to when the problem started I had the leftgate in the open position and left it open during a thunderstorm. It was partially backed into a garage but I'm sure the pushbutton got soaked because of the position. So, between the rain and whatever dirt got washed into the switch I'll bet your suggestion probably right. It's hopefully just dirt in the contacts that I can clean out with compressed air or by taking apart and cleaning. More later!

Fixed it! I took the interior plastic panel off the liftgate to get full access to the hardware. I removed the switch assembly and took it apart. Surprise! The switch is NOT really water or dirt proof. The plastic housing is recessed inside the door but can still be exposed to the elements especially when the liftgate is in the open position. I cleaned out the crud on the switch contacts and used a waterproof grease to lube it. I reassembled and she works like as new!
While I had access to all the linkages for the door lock I cleaned and lubricated all the cheap plastic pieces and levers to hopefully prevent the problem others have experienced.
Like a rock...yeah, right!

Well, crushed rock, maybe.
Glad you got it working.
