Now that it's getting cold out, my 1981 Deville rear power locks are getting pretty slow. Sometimes they'll lock, somtimes they won't. If I hold the switch long enough, sometimes that will work. They just seem a little sticky or dirty or something.

Any advice?

I tried removing the plastic screw on tops and shooting a bunch of WD-40 down the hole, but that did nothing.

The front locks work fine, and everything electrical on the car works fine too, except the trunk pull down. The power antenna is busted off and disconnected.

-istp :confused:

The ideal thing is to remove the door trim panel and lube the door latch assembly within the door. Over years rain water rinses away the lube inside the linkage causing it to bind. The solenoid that moves the linkage is probably good. My 84 Eldo had the same issue with the right door lock. I lubed the linkage within the door and all's well! I've seen rare cases where the electrical pins on the door lock switch corrode (turn green) and not enough electricity gets to the solenoid. Pull the master switch out of the driver door arm rest, pull the door lock connector off and clean the pins on the switch with rough sand paper or steel wool.

I had the same problem with my Fleetwood and if you wanna do it without taking anything apart, stick the little straw from the WD-40 and shove it into the latch when the door's open and soak everything. Worked with my car! Traditionally I would reccomend doing this once a year in October before it starts to get cold out because stuff slows down in the cold. I had one of my back doors freeze when it was open and it wouldn't latch when it was closed. I drove home with my mom in the backseat holding my door shut from where ever we were that night.......

WD-40 fixes everything!

Well, whatever Duct Tape doesn't fix!! :)

It's always one or the other, right? Haha.
