Asked by Shumway1995 Mar 28, 2018 at 05:00 PM about the 1999 Chevrolet Suburban K1500 LT 4WD

Question type: Maintenance & Repair

Replaced actuators in both passenger doors & driver door.  Replaced relay
under dash.  Replaced front passenger & front passenger switches.  When I
push the button to lock/unlock, only the driver side works.  The passenger
side tries, but it just doesn't happen.

Did you program the new fobs? Believe me, it happens. If you did, do it again, this may clear the problem.

Not too concerned with the fob. More concerned that it won’t lock/unlock on the passenger side with the door switch on either side.
