I did the fix. It worked for awhile, then quit after a long trip. The only thing i can figure is my wife fell asleep on the button and overheated the motors. That is why the thermal resistor is there in the first place, i guess. I took it all apart, the gear has melted, the brushes are burnt to dust, its bad.

As some have found out, without the thermistor, there is a danger of melting the motor if power is applied for too long of a time.

Is that a stock replacement or an aftermarket add on. I mean do I just take off the old and bolt on new, it fits right in. I've looked at actuators that you can add to any vehicle, but not sure if want that.

Correct,, you could just add the thermister in series with the plug and not inside the motor. This would still work and the thermistor could be a generic bought on the 12 v spec for temp rise. But why the effort. Why not just lay off the buttons.

If the thermister is in series with the motor brushes, and the power flows too long the resistance in the thermistor will go up to over 1000 ohms which will cut the current flow to 12 ma's which is .144 watts and not enough to burn a motor out. This is why you would put the thermister in series in the wiring. The plate thermistor is already in series with the brushes but internal.

can i use vaseline instead of dielectric grease on the penny? something else comparable? buying dielectric grease raises the cost of this fix by a staggering amount! 
thanx for all the great info in this thread btw.

Heat Sink Grease (6g)
Model: 276-1372 | Catalog #: 276-1372 $2.99
But consider the tube will probably do about 300 locks or about $.01 each. so still a cheap fix

K, I have to say, I am a much happier dude right now. I can't remember where I found the info, been searching on here so I could reply, but gave up.
Long story short, there is a posting in here somewhere stating how one guy fixed his actuators. I didn't want to spend $100 CDN each or buy some cheap crap off Ebay that wasn't specific to my truck, so I went through the steps this guy posted and man, am I impressed!!!!!!
To whom ever that was that posted about how to fix the actuators by getting at the little motors and replacing the thermal resistor, THANK YOU!!!!!! This was the best fix with NO COST I have ever done. Best part is that now the gear box (actuator housing) is now servicable. LOVE IT!!!!!
Cheers man!
:-)
PS - I can post that information on here if anyone else is interested, I just want to make sure no one thinks this was my idea, I most certainly do not want to take credit for this.
