    I was thinking that too. The HVAC box is disintegrating and dropping little chunks of plastic on the header, so I'll probably do something with sheetmetal for that too.

    Mine is doing the same but what he was talking about is that the same thing causing problems for you traction control also has the nasty habit of killing the blower motor.... it took mine out two years ago. Was very c arefull in positioning the wires back there to minimize the likely hood of another problem.

    That makes sense. If the inductance from the coil pack is affecting the speed sensor, which uses inductance to work, I'm sure it will affect the blower motor too. Just bought an electric sheet metal cutter tonight, so this weekend I'm going to design a shield that will hopefully protect those components.

    So is the temp fix still working...I keep getting a intermittent wheel speed sensor error too but on the left side. New hubs both sides.

    Still working fine. Off to the salvage yard this afternoon to see if I can find a 96 that has an intact RR strut, so that will be more miles to put on the fix. I'll post pics of my sheet metal faraday cage when I'm done with it too. It only takes a couple minutes to fold up some aluminum foil and test to see if it will fix your problem, so why not try it? Can't hurt. . .

    Unless you want a sheet metal shield for looks, the aluminum foil shield should work just fine as is.
