I recently swapped manual cloth seats w/ power leather from a totalled rig ('98 4 Runner) While tryin' to figure out hook-up, saw rear heater wiring running under passenger seat w/ same connectors, so I simply plugged passenger seat in. Worked like a charm until all of a sudden nothing (of course with the seat all the way forward). Is there a fuse for the rear heater that I could check first? Fuse for the power seat? Thanks - js
