Yeah but who knew there was a thermistor, I sure didn't, I would have bought new actuators thinking that they are an non-serviceable part. I did mine a couple of years ago, still going strong!

Don't wrap it in foil!!! First off I want to say thank you for the write up, there is a lot of insight there that really helped me out. Instead of the foil, take a pair of pliers and squeeze the thermistor. This will bring the resistance readings back into specs and retain its safety features.

Judging from the looks of the interior of your motor, mine must be burned out. Its covered with black on the armature and inside the plastic end of the motor that was removed - where the brushes are. I can't imagine that this would be dust from the brushes. Has anyone else experienced this?
Thanks

Door lock actuator problem continutes
I used a piece of copper as one of the other posters suggested. Put everything back together, plugged it up to the truck (w/o actually placing it back in its position) and its as it was before, not working. Makes me wonder if perhaps it might be the switch instead.
I shouldn't have to have both doors fixed in order for either one of them to work should I? Wouldn't think so but just thought I'd ask.

Unplug actuator test with test light when you push the button one is power one is ground and it swaps when you hit lock and unlock if no power when you push lock button its prob bad but make sure to check both buttons if nothing from either check the relay under dash behind radio area

Door lock actuators
I should have tested those switches at the time I tested the actuators. Wasn't thinking. I'm not sure if a switch can sorta work. When I was testing the actuator, it would only respond in the lock direction and not in the unlock direction and it was a very weak effort at that. But that is the same direction that the aftermarket actuators I purchased would work - only in one direction - and I don't remember them sounding very strong either. Not like the locks used to work. I tried both of those new aftermarkets and they acted exactly the same. That is why I'm thinking that maybe there is something else going on there. I'll test the switches and see where that takes me.
Thanks for the replys. I'll post the results of the switch test.
