It ends up only working on high. So I replaced it once located under the blower motor under the hood its quick to change. I put a new one it last for awhile then burns out only works on high after that. Could the blower motor be drawing to many amps any one know? It will be on its third one.

i have never fooled with one, but it does sound like its drawing too many amps somehow on the lower speed settings. this is just a guess (if it was mine this is what i would check for): look for amp draw on each speed setting (maybe there is a crossed wire or connection in the switch), is the blower itself touching or binding against anything causing extra friction. doubt that helps much but its a shot in the dark.

 

The blower motor sounds great im going to pull it and hook it to a 12 volt source and check the amp draw on each speed of a new resistor speed controller.
