My electric door in my 97 chevy venture is not working

Are the belts too tight?

Yes , but it involves taking the vehicle to a chevy dealer ! They would hook up the GM factory Tech2 scan tool . See if any codes are stored ,see if it will communicate with the tool . Should only cost about $26.00 buck .This isn't something for a non trained service tech. to mess with. The window not working is more then likely the regulater binding up . Would need to take door panel off to see what is wrong .

I guess you mean goes down when you press the electric button down and theres no sound orpower to go back up if you pust the button for down again it'll try to go down, but not up. If this is the case the window switch has failed, as long it's the window in the drivers door.

you have to take out the door ajar switch its in the door it works your interior lights and door ajar switch which is in the door and is hitched to the door latch

check for an open door ( all doors ) , defective courtesy light door switch, or short in interior light electrical circuitry.
