door handle locks up
any ideas?!?
Pull off your door panels, and see if a simple adjustment of some of the linkages will fix things. If not, pull the assemblies out and clean and inspect them. If they don't seem to operate 100% after you clean then, plan on replacing them.
Don't buy the cheap ones either, spend the money and get some good ones.
That said, I had a problem with my 79 driverside door latch not opening with the latch fully depressed. Our latch problem may not be related, but my solution was to adjust the linkage attached to the latch mechanism. It is easy to do once you have the door panel off, but removing the linkage rod clip is tricky. It slides straight off the end of the rod enabling you to remove the threaded adjuster end from the latch. The clip doesn't need to come off, just back far enough so the adjuster can be lifted from the latch. With this done, you can turn the threaded lug up or down the linkage for adjustment. If the clip falls down into the door, you could be in for a search. I tied a piece of dental floss to mine before pushing it back and freeing the rod lug. Good luck fixing your door latch.
I ended up taking the door latch assembly out to clean and lubricate it. After removing all the built up grease, and applying new lubrication, it works great without sticking anymore.
