I had Stip-Eze'd and resoldered the ACC PBU PCB some years back and it was working fine until I drove to Pbgh. for Christmas. The heat seemed to function correctly at something less than the maximum heat setting for 1/2-1 hour and then the heat gradually disappeared. I had to swith the thumb wheel past the click stop to max heat in order to get heat again. The problem is that all I could get was max heat, as the heat would disappear at any setting lower than max heat so I had to keep switching the heat on/off for the entire trip. I pulled the ACC PB unit while in Pbgh. and cleaned all the pin contacts, including those from the thumb wheel to the PCB, and thought I had solved the problem with a short (~5mi.) ride to determine if the heat functioned correctly at anything lower than the max heat setting. Upon leaving for my return trip to NC on Jan. 1, I found the ACC system doing the same thing as the heat would disappear at any thumb wheel setting lower than max heat so I was forced to turn the heat off/on for the entire return trip as well. Anybody got any ideas? TIA.
