95 Highline SOHC ATX, When I bought this car the lights for the climate control ***** worked on and off. If I tapped the front of it they would come on until I hit a bump or something. I took the faceplate off to try to fix it and in pulling the the bulbs out and checking them they don't work at all now. Nothing has been changed or modified and the controls still work. Checked fuse box and all are ok. Bought another climate control center at the JY and still no lights. I pulled the wire harness off and have power to the yellow wire. Any ideas???
