Where is my fuse box?

There are 2 separate fuse boxes - one on the front fender - usually on the driver's side and the second is in the trunk on the wall opposite the radio antennae side.

It could be the multi function relay. (MFR) DISCONNECT THE BATTERY. Its under the dash up by the beginning of the brake pedal. I know when it goes bad the radio doesn't work and the trunk and gas cap wont open. Its grey and will not be by the other relays. It can also be disassembled for general inspection. Upon disassembly of the unit It will have three small relays along with one large relay soldered to a silicon base chip. The harness end you can test with a multimeter to verify this unit is the problem. Its around fifty dollars for the part, I've replace five of them so it is a little common for this unit to go out.
