Cadillac Seville / Cadillac Eldorado Forum Discussion, 02 SLS Fuse Box Location in Past Cadillac Vehicle Discussion; I need to check the fuse for my driver's seat heat. Where is that particular fuse box located?
If you're talking about the SLS, it's under the rear seat, driver's side. The battery is on the passenger side. Be careful to unplug the heated seat connector on the passenger side, too.
Turn the key ON. Energize the seat heat and listen down at the lower front of the seat. Do you hear a click every 5 seconds or so ?? That's the circuit breaker in the seat heater module telling you that one of 2 or 3 heater elements is broken. Requires seat disassembly and install a GM-only repair kit, depending on which particular heater setup you have.
