2004 Pacifica power seat don't work

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.

BLOWER MOTOR IS LOCATED PASSENGER SIDE UNDER DASH. MIGHT HAVE A THIN PLASTIC TRIM COVER OVER IT

check the fuses front the driver near the battery

Your owners manual should list the 40amp fuse and the circuit breaker for the seats. The memory control module is powered by both.
If the module is getting power it may have failed.

there is 2 wiper motors . 1 for the drivres side and the other for the passenger. sounds like a bad passenger side motor

Did you check fuse

First check the fuse.

if you drive slowly does it not start? ensure you do not having anything resting on your passenger seat. if there is a weight sensor in the seat for the seatbelt warning the car assumes sombody is in the passenger seat. or the sensor is defective to isolate this plug the passenger seatbelt into its lock and see if the problem goes away. (when driving slowly this may not start. the alarm may be set to go of after a certain speed)

note: keep all clutter away from the driver position after cornering or breaking, debris may fall into the foot well and interfere with the pedal movement. or fall onto the driver.

If your alarm went off, it could be that someone had tried to break into your car. They most likely may have cut some of the wires inside your door with what ever device they may have been using. Look for evidence between the bottom of the windows and doors where the problem is. If not, then it is possible that your automatic window assemblies are malfunctioning. Do you hear the motors run on the windows when you go up or down with the switch? I also have a Pacifica, 2005, however no window problems yet.

Good Luck,

Ray

Hopefully by now you have resolved your problem but my truck had that problem and I had to replace the motor for the window controls.
