Power Seats System Description and Operation
Power Seat System Operation
There are 2 options of power seat systems available in full size trucks. The 6 way driver and passenger power seats, and 8 way driver and passenger power seats with driver memory. For the driver memory seat operation refer to Memory Seats Description and Operation . Power seats without memory are completely controlled through the power seat switch. Battery voltage is supplied to the power seat switch through the power seat circuit breaker. While the seat adjuster switches are in an inactive state the switch contacts are closed to the power seat switch ground circuit. When a power seat switch is pressed to an active state the switch contact is closed to the battery voltage supply circuit. Each seat adjuster motor is controlled by the power seat switch through 2 motor control circuits. The seat adjuster motors are bidirectional and the direction of adjuster motor rotation is determined by which of the adjuster motor control circuits is switched to battery voltage while the other remains grounded.
( I'm not good at wiring an running an ohm meter.) well then you need to take it to a qualified repair shop.
there is a wire or rod connected to this lever which may be broken or the plastic keeper broke and the rod fell out..need to see if this can be acessed and repaired or if a replacement seat from a tow yarsd is in order..good luck..
To repair your rear defroster you can buy a repair kit at either Autozone or Napa. Or just about any other automotive store.------------------------------------------------------------------------------ Car Key Programmers
Maybe you problem is with the switch, or check if power seat circuit has the regular fuse or rather one of those thermal ones.
Passenger compartment fuse panel
The fuse panel is located on the left hand side of the instrument panel facing the drivers side door.

I tired a new switch becauuse of th seat not going foward or backward, the other positions worked. The module needed replacing, the mechanic ordered a new one, but it was a different number. He could not fing that module for the passenger power seat1 any suggestions?
yep check fuse.if fuse good check to see if power going to switch if yes.sound like seat motor bad or there is a broke wire at switch going to power seat motor or the switch could be faulty.hot wire the power seat motor using jumper wires.if motor works problem in switch or it wires.if motor dont work it is faulty.
