fan switch
If you can help..... I have a tj sport, 2003. the interior fan only blows
at high. The heater is fine. I'm hopping that it only needs a switch replacement (which I also hope I can do myself)... has anyone else come across this? many thanks Mike |
Re: fan switch
Your switch should be fine, the fan has a direct line on high. There is
a resistor pack that controls the lower speeds and when it is burned out you get your symptoms. I think someone posted here about actually replacing the thermal fuse unit inside the pack that sometimes blows rather than just buying a new pack, but most folks just replace them. The resistor pack is located at the bottom of the heater air box in the passenger side footwell. I think there is a plastic cover on it that comes off with one or maybe two screws. Our Cherokee is one screw to loosen and a slot on the second. Sometimes when this resistor pack blows, it is because the heater motor is wearing out and drawing too many amps.

Re: fan switch
this is a common problem.. it has NEVER been the resistor in any of my
Jeeps.. it is the control panel with the tree switches.. i buy them from jeep they are about 65 my cost and take 10 minutes to replace! -- Jarod Sprauer Talk is JEEP at www.sprauermotorsports.com 281-807-JEEP (5337) "myke" <mykeb@sympatico.ca> wrote in message news:WJesf.4132$l87.225843@news20.bellglobal.com.. . > If you can help.....
