You could also unplug each one of those components one by one. Unplug the window switch and try everything. If that doesn’t work, hook it back up and unplug the radio. Repeat this process until you’ve took each variable out. Maybe the radio or window switch is causing a weird resistance issue that chokes out the voltage to the others.[/QUOTE]</p><p><br /></p>
