So this morning the fan switch stopped working. Pulled off cover everything looks OK, traced wires under pasenger side dash and found a melted plug end. Read some forums and found out is kinda commen. Phoned parts store they carry nothing phoned dealer he has nothing but an entire wire harness. Has anyone else had this and how did you replace the part?
yes very common .. fix is to replace the harness then add a relay for each fan speed ... the thin cheap wiring cannot handle the load of the fan as it gets dirty and the resistance builds ...
fixed hundreds of them ... [cheers]

xj's heater wiring is badly undersized like mr awesome avatar said. you can watch the voltage drop as soon as you turn it on .

Buy the harness and put a relay in,
