Question about Cars & Trucks
I have a 2004 chevy 3/4 ton 4x4 and when I'm driving down the road my dash lights will get real bright and eventually go back to normal. My questions is this a dash problem or is it a voltage problem like from the alternator.
First make sure your battery and ground connections are clean and tight. Next check relays and fuses. Then voltage test your alternator.

SOURCE: dimming lights and voltage drop
Its not unusual to have a sudden drop of volts. especially if you have something running like your a/c or heater that requires a lot of power to run. it will also do it when your fan kicks in. anything that requires power is going to kick down your voltage. i would not worry about it unless the battery starts to die overnight.

SOURCE: 4x4 doesn't engage
that box does engage the transfercase to 4x4,there is a small electric motor on the transfercase thats probably bad,try hitting it lightly with a hammer because just like an electric window motor it has brushes in it as well,but its possible that motor is shorting out causing it to draw alot from the charging system,at least my 1993 Ford Bronco did the same thing and thats what i replaced and now it works fine.

Here is the diagram,It is always a good idea to only disaasemble one side so you can use the other side as a reference,I also reccomend using a set od brake pliers,they will the disassembly and reassembly much easier.
