Wiring overheating and melting blower motor fan switch at 36,500 miles. Wiring overheating and melting multifunction switch for turn signals, headlamps, hazards, etc. . . At 37,800 miles. Unknown cause for either failure. Replaced blower motor control switch assembly after failure myself as it was only $25 usd and 10 minutes time. Now the multifunction switch is doing the same - melting and causing headlamps to fail. Is there a voltage control problem with the electrical systems to cause these failures? will the replaced parts fail again? will a fire result the next time? updated 02-01-08 updated 02/01/08.
