I have a 96 blazer, 4 door, my power seats dont work at all, not sure what to check, suggestions please???? thanks

 

Start by checking the fuses. If they are ok you will need to check the seat switch with a voltometer. If the switch has power going to it but no power going out, its the switch. If power is going to it and out, its the motor. If power is not getting to the switch, there is a wiring loom under neath the carpet, I believe its an orange wire that supplys the seat, look for a bad spot in the wire. Hope that helps.
