recurring door lock problems -

[usedcat]

About two months ago I replaced the rear passenger door lock actuator on my 2006 Tahoe as that lock had stopped working...to my amazement it actually worked after I replaced it but then it stopped working again today...

I am going to try to put in another new actuator I guess....unless someone thinks there is a different issue? Could i have gotten a bad replacement actuator or could there be something else causing that to fail?

Thanks

Is it a GM part or aftermarket... if aftermarket chances are its the actuator if it is a GM part look for a wire break in the door jam weatherstrip boot
