Customer Question

I have a 2005 z71 suburban back doors and rear gate will not unlock with door control. It's not a huge problem except when we put it in drive or lock the doors with the control we have to reach back and manually unlock and it is also impossible to ever get in the rear gate. Any suggestions?

Hi there, I am CAm. This issue is a bad contact in the lock or unlock relay in the left dash fuse block. The system uses both relays to achieve both lock and unlock, so a bad contact does not allow it to unlock. Try replacing those to correct this issue.
