Power seat problem...

My driver seat in my 07 f150 will only move backwards and seat only tilts up. when i try to move it the other way it just makes one "tick" but wont move. I looked under the seat and it is either the motor or the switch on the side of the seat huh? What else could it be or if anyone knows what to do that would be great. My girl drives my truck alot and it sucks that she cant move the chair forward.

If it's an 07, it should be under warranty. Take it to the dealer and have them fix it. If YOU mess with it, you could void the warranty.

The problem could be the switch, but since you get a click, I doubt it. If the motor moves the seat back, I don't see why it wouldn't turn the other way. But, something could be wrong with the gearing and that could be causing the problem.

its not under warranty. I know it has to be either the switch or the motor huh? I get a click but thats it. no movement. the up and down only works sometimes. So would it be the switch or motor and they can be replaced individually huh?

If you can get to the electrical inputs to the motor with a voltmeter, you can tell if the problem is in the switch. Or, if you can disconnect the wiring harness from the motor and probe the input wires with a voltmeter, you can do the same thing. I'd guess the switch and motor are separate components.

If, you find out the problem's the switch, you can just replace it, but I sure wouldn't do that without knowing for sure it's the problem.

If the problem's in the motor/drive, you'll probably have to get the seat out of the vehicle to troubleshoot it properly. If it's a "mechanical" fault, like misadjusted gears, you may be able to repair it. I find it hard to believe that the motor itself could be defective already in an 07.

My guess is though, you could get replacement parts (including the switch) from a salvage yard. I doubt the design has changed much in the past few years.

Quick test for the seat.

Disconnect the connector to the back of the power seat switch.

Apply power to the Red w/ white stripe wire ( pin 1 ) and ground to the yellow w/ white stripe ( pin 4 ).
This should move the seat either forward or back. If it does not move ( i.e. all the way back ) reverse the polarity, and the seat should move the other direction.

If not, the motor for the seat is bad ( as long as you have the correct color codes ).

If the seat moves, it is a power seat switch problem.

For the "seat only tilts up", sounds like this is the front motor only works in the up direction. This is the wire pairs :
yellow w/ light blue stripe and red w/ light blue stripe, same deal, apply power to one, ground to the other ( with the connector unplugged ) and the front should move one direction. If not ( again as in the motor limit has been reached ) reverse the polarity and the front should move the other direction.

You make no note about the rear seat height motor, if that works or not.

Power Seat switch is USD$ 38.59 from www.oemfordparts.com

The adjust itself is a complete set ( all 3 motors, limits and if memory, the memory settings ) and costs ~ USD$ 400.00. If this is an issue, you can always take the motor out, and beat it against something. if it is something like the power window motors on the previous MY trucks.

Good luck, hope the switch is your problem.

Thanks for that respnse bro! check this out... the seat started moving every direction for a lil bit today and now it is stuck only going up and back. the back was tilting but now it is not again. only goes up. Tomorrow maybe something different i dont know. I looked at the switch and it has i believe 6 wires coming out the back of it and they are all black. and they are like soldered in there and its not a plug. It works one day and then a hour later it is back to its old ways. i still have not got it to move forward tho at all.

Since it started working an ALL directions for a while, it's sounding a lot to me like a switch problem. I'm still bothered by the "click" though, when it doesn't work. SSCULLY, there's no relay in this circuit is there? The "click" tells me the switch is doing something, and the motor is not responding.

SSCULLY gave you good advice for troubleshooting though. Applying 12V to the motor inputs will tell you for sure if the motor/drive is at fault. And, probing the switch outputs with a voltmeter should tell you about the switch.

Jack,

No relay, switch operates the motors directly. Usually the click is the motor shaft has run to limit ( mechanical click ).

The other click noise could be the switch itself, but on my 2006, the only click I hear is when the motor is at limit, and the pressure comes off the output shaft of the motor.

That's kind of what I thought. It really sounds to me like the switch is commanding the motor to move, but the motor is sensing it can't. So, I'd bet the problem is in the motor/drive. (Kind of like my garage door opener does now and then - it moves up partway and then stops. There has to be some excessive resistance to movement in there somewhere, but I can't feel anything when I move the door manually).

i ordered new switch today. the switch is the problem.... moving the switch forward does nothing, no click. it is at its max going back. then sometimes if i push the switch to go down, it will go up. it kinda chooses what it wants to do. but i dont even get a click when trying to go forward. Its the switch im pretty sure.
