OK guys, new to the forum. I have a '98 Pontiac GTP, and the power windows, radio stop working at the exact same time. They may not work for weeks at end, then without doing anything, come back on (at the same time as well). Also, when they stop working, my overhead/map lights will not work either, as well as my steering wheel controls (obviously since they control the radio). I have checked all fuses (radio, pwr window, and steering wheel controls fuses, when not working will NOT have pwr going to them, but when working, WILL have power going to them). I've checked wiring, grounds, etc...googled common problems, all to no avail. So guys, any suggestions? Thanks
