Yea retarted . Sounds as though there is a short. right ,well you just have to start following wires start checking grounding wires on block, body and switches. Example my jeep had window problems found the wires that ran through door from front of engine had broken could not see brake but knew that the wires always moved at that spot so kept digging and fixed that spliced the wires back. you need to find wire diagram and start chasing down the break the rubbed together wires loose or broke ground common circuit malfunction .IT does suck but you can do it or pay 100.00 dollars an hour for somone else to do it
