Having problems with your 2005 Chevrolet Silverado 1500 2WD ?
The rear electric door locks on my 2005 Silverado will only lock occasionally. They unlock perfectly. It does not matter if I use the drivers button or the remote. I think that it is in the relay but I am not sure. I was able to 'rock' the switch for a while but that no longer works.
The lock actuator is weak in your case
