1992 Power Lock Problem

[cubg1]

Looking for some help with my power locks.
For some reason, my locks are hard to use, and the problem gets worse the colder it gets to the point that they won't acutate elecrically at all. For example, when I hit the unclock button, the actuator engages, but is unable to unlock the locking mechanisim in one motion. I need to repeatedly hit the unlock button and this "nudges" the mechanisim until the door unlocks. This can be visually seen as the unlock knob on the top of the door slowly creeps up out of the door. If I use the key from outside, it is hard to turn the lock cylinder at times and hard to pull up the knob on the inside of the door. In the summer time when it is warm, the problem isn't near as bad. I am wondering if it is an issue of:
-needing something lubricated and what
-weak acutator motors -how to diagnose
-poor design

Has anyone else experienced this, and what have they done to fix the problem. I can remember when I first bought the truck, the power windows would barely go up and down. It was just a matter of greasing all of the moving components on the windows, and they were as good as new. I am hoping the problem is as easily fixed.
Thanks,

get in there and check it out. thats the best way to fix a problem like this. sounds like that was what you did to fix your windows so just do it again.

Sounds like you just need to clean and lubricate all of the moving parts.

Thanks guys. Yeah, I had tried to lubricate things once before, but I can go that route again. If anyone else has ran into this though, feel free to provide what you did to fix it. Part of me thinks there is a bigger issue since it is affected by the temperature - I know grease can thicken when it gets colder so who knows.
