My first question is, this is what our truck is, but can someone explain what it means 1988 CHEVROLET V10 BLAZER 5.7L V8 TBI OHV 16V. Thanks Second we have automatic locks and windows, on the drivers side you hear the motor, but the window won't roll up. It also can't roll up the passengerside, but it can roll it down. Than on the passenger side it will lock the doors, but it can't unlock them. Do any of you know what the problem could be? Hope this makes sence Thanks a lot!
