Need help with electrical grimlens in a '90 Blazer. I pluged in my cell phone charger to the cig liter yesterday and it sparked. Now my radio, scanner and overhead lite aren't working when the door is open. When you shut the door everything will work but it flashes on and off. The under dash lite works as normal. If the door is closed and I turn off the key some thing clicks(alot), sounds like a blinker click. I changed the fuse for the radio and took out the blinker clicker(flasher) and everything still acts the same. HELP!!!
