Default Door lock issue

I can lock the passenger door using the door switches and key fob but I can’t unlock it all I can hear is a clic clic from the door control module

A relay has gone bad most likely. Pull the module and either replace the relays yourself or send the module out for repair.
Search for c5 corvette door module repair, there are several places that offer the service. ABS Fixer is one of them.

Here is the location of the relays on the door module and the new relays I bought out of ebay when replacing them
Replace both the lock and the unlock relay (same age and wear )

this is a easy repair, and if your not comfortable soldering in new relays, take it to a friendly cell phone repair shop and have them do it

Might as well replace the window relays too since you have it out anyway.

Where does that module live when it's not acting up? My key fob will unlock both doors, but the driver's side unlock button will not. Maybe I need to get out my soldering iron.

I had the same issue with my driver's door. I sent it out for repair to Maryland. Cost around $50.00 and turnaround a week and a half. Behind the door panel and easy removal. Guaranteed for life. Whose life I don't know... I'm very satisfied with the repair.

Thanks for that! When I had a C4, I was always removing the door panel! First to fix window sweeps, then to fiddle with the speakers, and so on.

I've had my C5 for about 5 years, now, so I suppose it's time I became acquainted with the insides of these door panels!
Thanks!

Paul, I think you have a different problem. The fob and the unlock button should both activate the relay. If the relay is bad neither of them will work.

I think you can hook up a scan tool you can see if the button is sending a signal but I'm not sure.
I can't figure out how to tag C5 Diag in a post, he would know for sure.
