    You definitely know what your talking about. What and how do i install a scan tool? Is it easier to just buy another wire harness?

There is a control module under the driver's seat

The electrical connection at the underside of the seat maybe melted. There is a main power feed and ground feed....right next to each other, (another GM brilliant move) and the ground wire can melt inside the plug and lose contact.

To fix the problem:

Reach under the seat at the plug and move the wires around while someone holds the power seat switch backward and the seat should move up and you can see the plug and wires.

Next unplug the seat wiring from the floor wiring and look at the plug
What you can do next is cut the red and black feed wires (the thick 10 gauge wires) and make a new connector and join them up by adding some wire to each and soldering them in place.

If that does not work then your power seat control module has blown. Go to your local junkyard and get a replacement out of a junked Tahoe

    If your drivers side power switch is broken you can also get that at a junkyard. A scan tool is used to check errors in all of your systems from the vehicle computer

There a few things that could be going on with the seat.Does the seat for starters look as if it is going beck and forward at the same length on both sides or sort of one side ahead of the other.This could be caused a weak motor or the cables that control the tracking of both sides bonding on one side or the other. there are other issues but to go deeper you would have to

  • Install a scan tool.
  • Observe the horizontal forward and rearward switch parameters in the driver seat module Input/Output data list.
  • there are other things that need to be viewed also.Does your seat have memory(personalization) or is it just a power seat. Testing is somewhat similar but has to be known.If you plan on going this deep on your own I am able to give you exact step by step troubleshooting for this but it requires a tech2 scan tool. I hope that this has helped in some way you understanding what it intails in repairing such a issue.

    2003 Chevy Trailblazer

    First you reach for the tab near the center of each "half" of the back seat bottom at the back (in the crack of the seat). Pull the tab forward and up, pivoting the bottom of the seat toward the front. Ensure the front seats are forward enough to allow the seat bottom to lie flat on the floor. Next, reach up along the (outer) side of the seat back, and lift the lever, while folding the seat back forward. You may need to pivot or remove the headrest(s). The seat back should lie flush atop the upside down seat bottom. This works for my 2002 Olds Bravada, which is supposed to be similar. Good luck!

    Driver power seat not working correctly . 1997 Chevy Tahoe. Driver seat will go up and down and starts to go back but stops and doesn't go forward make a zzzzzzzzzzznoise. Worked fine yesterday today it...

    this can be a few things, you may have a bad motor, or a broken cable to motor or seat track and last maybe a broken track, the best way to diagnose would be to remove the seat flip it over while still conected,meaning; remove the bolts at the bottom of the seat then push seat back toward the rear seat this way you can see the track, now move the controls as you watch the track,it may go sideways instead of straight back or foward this will show you what side is not working from there you can see if its a cable broken or track or motor not turning .

    Cant fold down the rear seat in our 1997 Chevy Tahoe

    in the middle of the seat cushions in the back of the seat there is a little loop, pull that loop forward and that will have the seat's bottom pulled down to the floor agains the back of the front seats. Next simply apply a lil muscle to the back of the back seats and the seats should fold down nicely into the open space. Be sure to remove the headrests so the seat will fold all the way down. post any issues u may have.

    2003 chevy tahoe 2nd row seating

    lower the bottom portion, there will be two black cables. follow them toward the back of the seat, past a black round plate, where they become top and bottom cables. Push down toward the floor board on the bottom cable (my bottom cable is no longer black coated but rather a bare feeling cable wire). When pushing down on the bottom cable, pull the seat forward. As the seat does come forward the headrest will fold back at the same time. Not an easy find for me either, they should just make a release lever, but oh well..... I Hope this helps. Just keep playing around with those two cables until it finally does release.
