Here is a screen shot of a resister I caught coming on all by itself. Aux a is tapped into the blower fuse. Notice the Amp draw and the battery voltage drop. This was back in 2007 when no one knew what was causing this. The dealer had installed a new resister already. The new resister was faulty we were able to catch and prove it.

1. Do not argue with an idiot. He will drag you down to his level and beat you with experience.
2. Light travels faster than sound. This is why some people appear bright until you hear them speak.
