This may be a dumb question and not work at all. I live in Canada so I use the rear defrost quite often. When I turn it on, the headlights dim. I have a 1 Farad capacitor on my stero and I was wondering if I could do the same type thing on my rear defrost. I know the capacitor on the stereo is for sudden jumps so this probably wouldn't work... But would it?

I've got a '97 that does that - Almost makes me think it's normal (Depending on how much they dim down). My aunt said her '99 did it until she had the alternator and battery replaced though. :dunno:

A capacitor will do zero good. Rear defrost pulls a fairly heavy current from the electrical system, so some very minor dimming would be more or less normal. All depends on your definition of "very minor". If the dimming is severe, could be a sign of a failing alt or batt, loose batt cables, bad major grounds, etc.

Battery would have nothing to do with it if the engine is running. More that likely the alternator is worn and not putting out the high voltage it should under large loads.

You're going to have dimming when the defogger is on, it's normal. As it's been already said, the rear defogger is a heavy draw on the charging systems, and you can add the heated mirrors for those of us that have them. If it's night, you're going to have your headlights on, plus the rear defogger, and I'd assume with the time of year the heater will be on as well. Not to mention other need accessories and stuff like stereo, etc. That's a decent size load placed on the alternator. If you're stopped at a light or just idling the revs are not up high enough to put maximum output from the alternator. So therefor the lights will dim slightly.

I upgraded mine to a 36volt 840 ampere hour rated system.

Stopped all the dimming but it weighs 2800 lbs
