I don't drive the car often and it seems the airmatic drained the battery. I was having a buddy help me pop the trunk, but putting a jump box on the terminals under the passenger foot well. Basically he had the positive on the negative terminal in error because it was a big red wire. The car horn beeped and it spit out wiper fluid. Now the radio won't work and the window shade won't go done. I checked the fuses under the hood, on the drivers side front and in the trunk and couldn't find a bad fuse?? In fact I couldn't find any fuses bad. Does anyone know where else to check? Does the radio have fuse behind the radio if I pulled it out of the dash that may have blow? Also is there anyway to just put the shade screen down? I never used it and won't mind if it didn't work, but it's stuck in the up position and I can't see at night...
