My 1994 Z28 seems to have a weird little problem, when I turn on my headlights my power windows wont go up or down along with a few other things that mess up.......... anyone know whats up?

 

what does the volt gage do while this is goin on?

 

IDK gage gose to empty, I will have to see what the volt g dose,

 

Voltage g just stays in the middle and dosn't move during this
I can roll my windows up and down if I open my door and turn my dome light on

 

check all your connections at the battery and the power junction box. take the battery cables lose and wire brush the heck outa the battery terminals and the cable ends. do the same for the junction box ends. check the connections and wires to the alternator. if none of these help have the battery and alternator tested, if you have a voltage tester test the volts at the battery running and not. check voltage at the alternator while running as well.

 

you have grounds that could be checked. just a minute

 

you have a ground on the block in front of the starter. one on the passenger side motor mount, one on the front of the block on the driver side by the coil, one under the belt tensioner. your also have power and ground junction boxes on the passenger side wheelwell that you could cleanup with a wire brush.
heres a couple grounds inside g200 and g201

 

Thats alot of grounds, Ive had the car for about a month and its in real nice shape, it dosnt do it all the time its just doing it alot today.

 

Dumb? I have a busted tail light, any chance the water getting in there could make a short and couse all this? It did happen the first time in the rain, and I did just wash the car yesterday.

 

check out the light socket and see if its all corroded. look over the wiring under/behind the cover/carpet.
