Question about 2000 Chevrolet Venture
The buttons for the windows and lock buttons dont work, I would like to try and fix this myself so if anyone can help me that would be great.
I'm guessing that you are able to lock and unlock doors with key. if you can't do that you have a mechanical problem to address first. you should be able to lock and unlock at least the doors that have a place to put the key that way. the other problem you have sounds like an electrical problem. first i would look in the fuse box in the passenger compartment and see if you have a fuse blown for that circuit. if you do replace it and see what happens. whatever caused that fuse to blow might make it blow again, or you may not have a blown fuse at all. i would check that first because it's the easiest thing that you can do in this situation. next place you need to look is in the driver's side door. when everything is working right you can open all the windows and lock or unlock all the door locks from the driver's side door controls so current for all these controls pass through those switches. like most switches they control one side of circuit. after you get the door shell off you can check these circuits for power. you will need a 12 volt test light, can get one at a car parts store pretty cheap. touch one side of the light to ground, pretty much any exposed metal you can get to, and the other side to one conductor of switch. if you get no power (light doesn't light up) to one side of switch try the other side. if you don't get any power to switches you are going to have to follow those wires and see where they go, check the connections where they end up. if you get power then check the ground for that system. you can loosen the ground connection and clean it up real good and put it back together. you could have bad wire somewhere in that system somewhere, to test that you will need some extra wire. cut a piece of wire same gauge and roughly same length and see what happens if you put the new piece between two points. only use wire to test existing connections, in other words to make a new connection where a connection already exists. this will tell you if you have a break in a wire. it is possible that all your switches are bad but i would not suspect that unless car has sat for awhile with windows down and water has gotten into switches. one bad switch i could believe but they don't ususally all fail at once. hope this helps.

On our van, the wiring harness on the floor, located on the passenger side under carpet. Pry off the door sill cover on passenger door, lift up carpeting up to edge of the seat. You will see a factory splice where wires join to the driver side. These connections corrode off! Check each wire and rejoin carefully with waterproof connectors. Seal total repair with electrical tape. Whe I did this on our van power locks worked again and windows operated at original factory speed. Good Luck.
