Passenger side door lock has been acting up. I need the part # for the little motor/actuator thing that locks and unlocks the passenger side power door lock. I was quoted around $75 from the dealer and would like to find it cheaper if possible. Also, I was quoted $35 for the trunk lock motor/actuator as well. Anybody know this part #? The dealer refuses to give me either part #, to try to make me buy it from them!

Left side latch actuator #16636561
Latch actuator for the trunk #16630424

 

I thought he wanted the passenger actuator (RH)? GM PART # 25664287 is what I see it as in the book and it looks to have been changed to GM PART # 16640848.

I would test that actuator to be sure it is the cuprit. Might just be the switch. List price on the actuator is only ~$65 and sells wholesale for ~$32.
The trunk actuator is only ~$14 wholesale.
Sources for GM parts.

 

sorry Shoebox....so is this correct?.....
16640848 is the new trunk lock actuator part #
25664287 is the new passenger (RH) door lock actuator part #

 

16640848 is the number for the RH door lock actuator.
16630424 is for the trunk latch, as I did not mention that it could be wrong.

Sorry, what I wrote before made sense to me.

 

the door switches themselves on these cars are for junk just replacing them alone could solve your problem. There was a bulletin posted by Gm stating this a long time back.

Even slow window motors have been traced back to the switches not having good contact.
