Ok, here's another on the way home from dropping my son off thing. So I'm on my way home tonight and I noticed about half way home that everytime I step on the brake pedal the light for my rear defrost comes on. It only does it while I'm driving though. While sitting at a stop light or at speeds under 15 mph it doesn't happen. It even does it while I have the clutch pressed in. The light is only half bright (except for one time it was full bright) and I also pushed the botton for the rear defrost while the brake was pushed in and nothin bad happened.

Can someone give me some ideas on what it could be and where I could start to look for the problem. I have no odd smells like melting plastic (wires), No cels, It seems that everything else works normal. Well, I didn't work the wipers and all that but the stereo works fine along with the lights and all the dash lights. None of the other dash lights go funky when the pedal is pressed ...... Just the rear defrost light.
