Hi guys i recently changed the generator on my impala ls 2000 cause it was old and it died, also bought a new battery.

both of them are working great, but theres a problem, if you push up or down on the power windows buttons "located where the driver side" the red battery light appears for a moment, and the intesity of the lights goes down like if it was draining power or shuitting down the generator, also it only happens with that console, it does not happens if you use the other windows buttons.

does this consoles goes bad? whay should i do? thanks.

Could be the switch or the motor....

A loose battery cables can causing weird issues. Also need to check your grounds at the body.

Both good ideas^
If the battery light is coming on..after the alt & battery was changed...
I would like to know what the voltage is at the battery while car is running and then what happens to the voltage when you activate the power window button.
Also after the car is shut off for 10 minutes, w/doors closed etc-no power drains, what is the voltage reading?

solved,it was a wire that was doign ground and draining the battery : D
