My '99 Bonnie keeps eating high speed blower relays. They'll work for a day or two on high speed and just quit. The other speeds continue to work fine. I know high speed is it's own circuit and I'm looking for a wiring diagram to trace the problem. I'd like to test resistance at the blower motor. Does anyone know what it should be? Please let me know.

do you know if it is coil or contacts. if not and you have an ohm meter, check which is faulty as a first step. http://i281.photobucket.com/albums/kk20 ... 9374113371

Update: must have been something internal with the blower motor. It spun fine, no bearing noise, but I installed a new motor and high speed relay a couple months ago and so far there are no problems.

Update: still burning up the relay. The new motor helped extend the relay's life up to a point, but still burning out. Will do a further check of the ground circuit.
