Door locks problems

[vwracing65]

hello, I own a 98 Suburban and all the door locks stop working including the rear door. I've read about fuses bad, but that all fine ( Cig lighter, mirrors, power seats, heated mirrors ). The door lock relay under the dash click when you hit the door lock switch. Don't know what to do.

maybe switch the relay just to SWAG it. (scientific wild ass guess) other than that get out the test light or DVOM

Bad actuators? I've replaced two in my '08 within the past ten months.

I can see that the actuators are trying to move

bad ground or voltage drop, UMMMMMM

You could try unplugging and replugging the connector at the drivers side door switch. My locks seemed to work better after doing this a few times. Maybe voltage drop due to minor corrosion build up at that switch or just poor contacts at that switch. You could also test the voltage with a multimeter at each actuator. It should be close to your battery voltage.
