have a problem with dimming everytime i push my window button the gauge light, and everything dim and idle change what do you guys think the problem is, should i change the battery, i also hook up buddy club ground kit

 

i'd definitely check the status of your battery, alternator, and the heavy gauge wires that attach to them (i've seen crazy corrosion in the harness at the alternator). make sure your ground setup is effective... and maybe check and make sure you don't have any crazy "custom" electrical stuff goin on anywhere (it doesn't look like an electrician threw up under your dash, does it? if so, clean all that ish up)
