I replaced mine 4 times....first they told me to just keep replacing them as its the only fix, then finally they mentioned to me that the blow motors themselves cause the resistor cards to blow...fackers. :banana2:
Easy fix, two Torx screws right behind the glove box.
lol, not surprised at all. They did revise the resistor at one point though. The one i took out was much different than the one I installed.
I had half the dash ripped out at first looking for the thing...then I looked under the dash :funny:
Thankfully Lockwood got it in for me within a day and I had heat again. No heat in January is not nice lol
But I don't know if there is an easier/cheaper problem to fix
