'99 STS:

My trunk and fuel door release buttons aren't working at all. I've located the RELAY in the Fuse/Relay box from the back seat where the battery is, but I CAN NOT FIND THE FUSE. Does anyone know what it's called? There are all kind of abbreviations and things and I have no idea what it would be labeled as. PLEASE HELP ASAP.

I've locked my keys in the trunk and can't get in there!

 

I don't have the diagram for your car, but every car owners manual has a description of every fuse and relay and where it is located and what it runs.
If you don't have an owners manual maybe someone here that has one can help youfurther.
Good luck.

 

Body and ALDL fuses power relays.Valet switch in glove box. RIM control relays. If you know a liitle about auto electrical you can jump relay terminals and pop trunk.

 

I know it sounds stupid but check the valet switch in the glove box and make sure it is turned off. Sounds like this might be your problem......Good luck

 

thank you, that was exactly my problem.
