Power door lock motors R&R.
All my doors lock motors are weak. On a hot day the sunny side door lock(s) will not work by remote fob more than once or twice in a row. I notice the PS front door handle was loose. So I needed to get in that door panel to tighten the handle before winter, so water wouldn't leak in door panel. So I elected to go-head and R&R that door locks motor while tightening handle.
Once I had mine old motor out and knew for sure which motors (brass fitting on shafts) I needed. I then bought 5 motors off eBay for $20 to my door.
Separating the clam shell that holds the motors is a PITA. I've a tinny clever that was helpfully to pry around the seam. Basically we bust the seam. Heat helps but does not really release the sealed seams
I pulled the motor apart to examine why it was failing. But really the brushes and commutator didn't look that bad. Just a little grimy. So my thinking is: As the motor ages resistance goes up from despots on brushes & commutator. That the wire running through the doors also build resistance over time, so do wires harness from 12V power and grounds. Then on hot days, resistance goes even higher. Then using motor creates more heat, which again increase resistance. Then these micro motor just can't get the volts needed to operate is my guess.
Reading stores about how they replacement don't last and speaking offline with @abuck99 who hand done the job. Consensus was these Chinese replacement motors will only last a few years. So I wanted to make sure the clam shell case was not to difficult to open back up a next time if needed. So I found a glue (E6000) that was stated to hold up to 180 F. That is more heat then the inside of a door will get to just sitting in the sun in hottest place on earth (according to cargo container research I dig up)
I went ahead and installed the new motor and glued the clam shell back together.
This was a year ago and so far all good. I have purchased the Camry motor in clam shell it's said they can be modified to work and believed too last longer. For now I'm just testing the one motor. My GF and I just need to be watchful on hot sunny days that all doors did lock when remote key fob used.

Door Lock Actuator Replacement
I had the normal symptoms of a door lock actuator gone bad (many threads on this) so I went about investigating this issue over the weekend. I was hoping I could find something that could be remedied by a little bit of cleaning / maintenance, but that wasn't the case. Removal of the door...
