Power seat will not reverse - electric switch will drive seat forward but reverse setting will not do anything. Are there seperate motors for forward and reverse and is there a way to move the seat manually. Thanks for your help. Gerald

There are three motors. The one motor moves the seat forward and reverse, one for up and down and one for the tilt. So you may have a problem with the switch. It's possible the switch contacts inside have worn out.

Drivers seat switch that moves the seat forward & back as started to work in reverse sometimes, not always. It will also go fully forward however only half way back. any advise?


faulty switch
and inspect the seat movement mechanism and its motor

before removing the seat
undo both battery terminals
seat and seat belt restraint often are linked to the air bag system
warning light

some electric seats use one motor some use two depending on seat weight and design

Drivers seat does not move in the backward mode.all the other switch functions work properly.the seat is all the way forward and I cannot get in the drivers seat. I appreciate your help, thank you.


ssqsantiago, What you have to do is look under the seat and look for the electrical connections. You may find that one of the connections has a broken wire. If not, then disconnect each connection one at a time and look for any rusted pin or wires. If there are none of the above then what you can do is to figure out which motor moves the seat forward and backward and apply direct power to the motor. You will need a 12 volt battery for this and wires long enough to reach the motors connection. If the motor does not react to the power source then reverse the wires. If the motor still does not react at this time then the motor will have to be replaced. What you can do in the meantime is remove the motor and try to move the seat manually. Good luck with this.

Subaru outback all wheel drive electric seat switch stuck


I just went through and determined it was the switch. My wife had accidentally moved the seat almost all of the way forward - and the reverse did not work at all - she was very cramped. After going thru fuses and seeing that none were blown I looked for loose wiring under the seat and found none. I was about to pull the seat when I stopped and decide to pull the side cover first. Item 5 in the photo below. Once that was off access to the switch was easy - item 3. The box actually contains a set of 3 switch housings each with 2 switches on it - total of 6 for each direction. I unplugged the large connector to this switch. Then I cut some wire off of a roll of wire i had in the garage and stripped both ends. I put one wire into the power contact (red) and the other into ground (black) and then took the other end of both wires and connected them across the other contacts in the connector. Pretty quickly I could determine which pair of contacts controlled which motor. I got the right combination that allowed me to operate the seat-reverse motor and get the seat back into the right position... problem solved. I still need to find a replacement switch box at a junk yard but no hurry now that the seat is back to a comfortable position.

Horn and power seats quit working. maxi-fuse extremely hot. pulled it out and re-inserted after it cooled down. fixed the problem temporarily (a day or so). swapped that maxi-fuse with the one above it...


which maxi fuse gets hot ? # fuse , plus amps The power seats uses a 30 amp circuit breaker ,not a fuse . The horn gets power from the same circuit breaker . . Sounds like something is drawing to much current. Do you know how to use a amp meter to test current flow . Disconnect componets till draw goes away ? How to use a wiring diagram to pin point areas in a circuit to test ?
Is there corrosion on the pins where the seat circuit breaker plugs into ? Reach under your seats an see if one of the seat motors is hot .

The left and the right power seat system consist of the following components:
• The seat switches
• The seat relay modules
• The 4 reversible motors:
- The front vertical motor
- The rear vertical motor
- The horizontal motor
- The recline motor
These 4 motors operate independently of each other.
When the entire seat switch is pushed to the FORWARD position, the forward input of the of the seat relay is grounded.
The seat relay module supplies battery positive voltage (B+) with a ground to the horizontal motor, in response to this input. In order to drive the seat forward, the motor runs until the switch is released.
The BACK position works similar to the FORWARD position with the exception that the voltage polarity supplied by the seat relay module is reversed causing the motor to run in the opposite direction. This action drives the seat backward.
These recline switches operate similar but independently:

The seat relay module could be bad , If you don't know how to do automotive electrical circuit testing it mite be a good idea for you to take your vehicle to a qualified repair shop.
Could have diagnostic trouble codes stored as well .

Power driver seat in F150 moves back but not forward


Just picking at you. It would have to be a bad switch. Forward and back are on the same circuit switch just reverses the power and ground to the motor.

2005 KIA Optima EX 8-way power seat problem


Hi there,

There are numbers of possible causes to your problem. There might be something causing the movable parts to stuck up. It could be the limit switch, or the motor itself. To test the motor, you can connect it directly to the battery then check if the motor runs smoothly. Then reverse the connection and observe if it reverse smoothly. If the motor is OK, then your problem is with the switch...

Regards,

Bmw seat wont go back


The power seat uses DC motors. To change direction the polarity reverses from one direction to another. If you hear the motor "clicking" when you try to drive it forward, even though it is already forward, this signals the motor brushes are making contact to the commutator. So if it is "clicking" the problem is most likely the rearward seat movement switch itself or bad connection from the seat switch to the motor. If there is no "clicking" sound, this indicates no power is reaching the motor, it is most likely hair, dust or trash that has entered the motor and become lodged under the brushes, preventing failure of the electric circuit to the commutator. Unbolt the seat, remove it from the car and be careful with disassembly and cleaning of the motor, they can be difficult to reassemble as they have permanent magnets. I am not certain on your BMW, but many manufacturers use a motor with an open end that you can manually rotate the motor by hand with a piece of square key stock, this may also dislodge any debris stuck under the brushes and allow the motor to operate.

Front seat wont go front or back.


Could be 1 of 2 things. The switch on the side of the seat could be bad or the motor for the forward and reverse is bad. But lets hope something is blocking it and can be removed. I think the switches for those two operations should be sold seperately.
