Thanks Marc. Both my trunk release and fuel-door release buttons stopped working at the same time on the driver's door. I did see the relays; but is there some common power source for both of them that I may have blown the fuse on? Much appreciated, Greg
Turns out it was the ALDL (Assembly Line Diagnostic Link) fuse - or in other words the one that powers the OBD2 connector, that blew. It's #4 in the rear seat fuse box. Now my door buttons for trunk release and fuel door release are working perfectly again. Yay! A tiny victory!
