80 Vette. The driver side power door lock comes up half way. Can't pull it up any farther by hand, door is locked can't open. Can anyone tell me what to look for. Will I have to pull panel?

If you cant pull it up by hand your going to have to pull the panel. Something is stuck or broke inside and there is no way of fixing it unless you pull the panel.

Doc here,

Common problem on the 80's The one in the Avatar has the same problem about twice a year...

Caused by a combination of things, poor linkage alignment of the solenoid to lock linkage, or Dirt caught up in the turn points, or solenoid piston, or just a weak solenoid..or bad ground to it...

First try as I have, spray some graphite in the lock plunger then cycle it a bunch of times..If that doesn't do it, try some silicone lube spray..(you have to get almost sloppy with it) and cycle it again...If not...

It's not just a job..but an adventure..pull the door panel, clean and lube all the linkage points..than inspect for any bends. Inspect the solenoid plunger arm for burrs or dirt and clean or replace, and be sure you have a solid ground.

Lastly, be sure you don't have a bad connection through the Vehicle alarm system, stock harness located in the center console , forward of the radio, on the left side, will consist of (should at least) same color wire in, out, and into the brain box.

That should fix the problem.
