93 Camry Dimming dash lights etc.

[LUVLEXUS101]

Is it normal for when my car is idling at say about 800 rpm, and I close my power windows up or anything like that all the dash lights and even the headlights somewhat as well. If I do more than one window at once it gets even dimmer. If I'm simply idling and I rev it up to say 1000 or 1200, everything gets a bit brighter. Any Ideas? I believe the alternator was changed a couple years back. On the other hand, is this normal?

I have replaced my car battery about 5 months ago, and I have a similar situation. While I use my power windows I do notice my dash lights and my head lights dim slightly. Other than this I do not notice anything electronically wrong with my car. I would recommend that you clean the heads of your battery, and maybe somehow check to see if your battery needs to be changed.

I'll try cleaning the heads of the battery, Im sure its not the actual battery, I get it replaced every 2 years at Sears using the warranty

It;s normal, not an issue. Happened on my old '92 5SFE, happenes on my dad's '96 5SFE wagon, and happenes on my '96 1MZ-FE.

^ Other than cleaning the battery posts, is there any other things to look into? My dash lights dim pretty bad. Replace grounds? Get a thicker gauge wire for the ground?
