I have a 2008 Suburban and the drivers door lock actuator is bad doe any one know the part number. I tried to look it up and it gives several part numbers so I don't want to order the wrong one Thanks

 

I have an 08 Tahoe and have had 3 of the 4 replaced, and the 4th one just died. This is a common issue with these and am surprised that they have not been recalled yet. It is a dealer only item and the parts department at your local dealer should be able to get the part number for you.

 

Welcome to the forum both of you,
Might check GM parts Direct, they have a listing and they run about $65, but the part number will depend on the model and options you have....
