The Car-1996 Pontac Sunfire, 2.2L, automatic transmission The Problem, A few weeks ago, when I started my car and put it into reverse everything on the instrument panel started acting haywire. The instrument gauges were acting erratic (bouncing around for no apparent reason), Headlights extremely dim, wipers running very slow, and the stereo turning on and off when applyng the brakes ore taking my foot on and off of the accelerator. I have since put in a new battery and alternator and neither have made a difference. The headlights are still very dim, the wipers are slow, the heat only works full blast when the car is idle (when driving it is signifigantly lower), the stereo cuts in and out when applying the brake or taking my foot on/off the accelerator, most service lights are on when driving yet the majority shut off when idle. Also, things like turning on the rear defrost or using the turn signal will cause the stereo to shut off and then come back on. I suspect that there is a short somewhere in the system but have no idea on how to go about diagnosing it if in fact that is the problem. Any help would be greatly appreciated. BTW, the car starts just fine. I have no problems with stalling or anything like that. Thanks, Daryl

I suspect I will need a new windshield in the morning [a piece of ice hit it when it was warm, and I heard that sharp crack that I know means it will break when the temperature drops to the single digits tonight]. I drive into the sun a lot, and get blinded by the light caught in all those little scratches and dings. Is there anything one can do to a new windshield to minimize them?
