Hi I have an 03 Tahoe WT and my driver door doesn’t unlock with the driver unlock button. It locks with the button but won’t unlock, it will lock and unlock with the passenger buttons. I’ve replaced the door lock actuator with an AC delco one and I’ve cleaned the contacts on the driver door switch. Any ideas?

 

Welcome from Florida. It sounds like the door switch is bad. Cleaning the contacts work sometimes but not always.
