i cannot get the buttons to operate on my 1989 riviera there doesn't appear to be any fuses blown
trunk and fueldoor buttons on 1990 Buick Riviera
Fuse #17 (20 amp) is for the fuel door & trunk release. You have a release solenoid for the fuel door & the trunk release is built into the trunk door actuator. The fuel door release solenoid is located left side of trunk above the wheel well. You need to check the power at the switches and then go to the release solenoid and check power.
