If they do not then you may have a bigger issue.
1999 chevy tahoe rear door power lock not working.
If they work then you ve narrowed down your problem.
Years ago the rear right door lock quit working but that is just extra info.
For vehicles with traditional style door lock cylinders and keys a bad power door lock relay will merely disable the power door lock feature.
It is a 2002 honda accord 4cyl special edition.
However vehicles without door lock cylinders will not be able to lock or unlock the doors until power is restored.
1999 tahoe 4 door 4x4 the driver passenger side power door locks are intermittently or not working at all.
However when it is hot 104 f like it was today the locks do not respond to any of the switches driver front passenger.
The other three door locks work fine when it is not hot.
The drivers side pdl never responds when the switch is used and the passenger occasinally works.
The rear barn door does t work as well.
Here is my story.
Very frustrating have always owned chevy but with oil cunsumption and this problem it will probably my last one.
One of the easiest ways to diagnose the switch is by trying to use other door locks in the car.
The driver lock has completely quit and the other 3 doors work randomly.
