Are you talking about your Heater Fan located

in the cab above the passengers feet????

The Espar simply supplies 12V to the blower motor. All of the switching is done on the negative side of the blower motor. My guess is that you have a bad 12V power supply to the blower motor. If fuses are good, then the problem must be the wiring. First place I would look would be where the Espar power supply was spliced into the stock wiring. Otherwise, I would use a test light and start tracing the power wire. I am not too familiar with the routing of that wire, but it's easy to find under the passenger side dash.



Until you get it fixed (winter) you can just drive around with the Espar on, and I doubt you would even know there's a problem.

Good luck.

Ya thats what im doing now running the espar while driving. Espar uses a plug that goes between the factory plug on fan.
