SOURCE: Front driver seat adjustments.

I just had this problem fixed with a Tech 2 tool in my '03 yukon xl denali. The seat has a control module underneath of it that controls the 2-position memory, the power seat functions, etc. It needed to be reprogrammed - about $200 at the dealership, or free if you 1) have a good relationship with your service manager, or 2) own or know someone with a Tech 2 tool.

At first I thought it was because I had a Canadian model truck (the headlight switch is stuck "on" at all times no matter what position it's in, and the rear air controls are in celcius and not farenheight).

I'm assuming the switch worked before, and you may have encountered some sort of electrical issue (like a dead battery, or you gave someone a jump, you have a bad ground, you just installed an aftermarket stereo, you used a computer tuner, etc.).

Hope this helps!

MY DRIVERS SIDE POWER SEAT WONT GO BACK OR FORWARD BUT ALL OTHER PARTS OF THE SEAT WORK FINE I CAN HEAR SOMETHING CLICKING WHEN I TRY TO MOVE THE SEAT BUT THE SEAT WONT GO BACK OR FORWARD


Check under the seat for broken wires. Forward and backwards is the function most used and causes the wires to bend back and forth. you may need to remove the seat for inspection or you may be lucky and see the problem just by raising the seat as high as it will go.

My driver side seat won't go all the way forward. But when I let it back it goes back and goes down. When I move it forward it lifts up high but don't go forward enough for me.


Seat adjustment ranges are sometimes limited and sometimes there is a fault, such as a coin or something falling into one of the runners.

Cars intended for the premium market often have forward/back, up/down and sometimes tilt adjustment for the driver seat while for the small car, basic or budget market usually only have forward or back. Because on average a person who has shorter legs and needs the seat forward will also have a shorter body so enterprising designers have made the seat runners of some models slope upwards to lift the driver as the seat is moved forward.

Adjustable steering columns are fairly common, though only in the rise/fall plane. I haven't seen a telescopic column for many years. What is really needed is adjustable pedals but designers and manufacturers are very reluctant to go down that avenue, though there are companies specialising in such modifications.

You need to be on the ground on your knees with a good light looking under the seat to see if the available adjustment range takes the seat to the true limit of its travel in both directions.

Drivers not moving


If the controls still work to move the seat up and down and the seat back forward and back then you've ruled out a fuse. The switch could be faulty, could be a broken wire to the motor or the motor itself could be bad.

Driver seat wont move back


Of course they do not have to buy the seat. You can remove the seat and some tracks bolt to the bottom which you can replace with a good used one for less than half the $$$ .

I have an 03 lincoln navigator the driver seat wont go forward or backward it can only go up and down, but every time touch the switch i hear a click, what can be my problem and what can be done to solve...


Most Ford products are designed so the seat belt latch by the center console moves with the seat. The bottom of the latch rides on the seat rail, and with time sometimes it builds up a little play on the rail. As the seat moves forward or back, the seat belt guide often tilts forward or back, just a bit, on the rail, and gets stuck. So you can move forward or back just a bit, but then it jams and you can hear the motor, but can go no further.

The long term fix is to remove the seat, disassemble the seat belt guide and rail, and usually replace some parts.

But the short term solution is often to simply hold on to the seat belt latch and rock it forward and away from the seat as you try to go forward or back. Or, sometimes it works best to rock it backwards and away from the seat as you try to move forward or back. It all depends on which way it is binding.

There's no guarantee that it won't jam again if you move it all the way back or forward, but once you find the right position to hold the seat latch in while moving the seat, you should be able to re-adjust it where you need it to be.

Passenger seat will not slide forward


there will be bars underneath the seat that are supposed to go across to unlock both sides so that the seat can move forward and back, try having someone pull the lever and see if you can see from behind the bar that moves and figure out what it corresponds to on the opposite side. you should be able to move it by hand, release the lock and set the seat where you want it, as for a permanent fix, most seats are not difficult to remove, typically four bolts, although some take specialty tools like large torx bits, and i would imagine the bar is replaceable

Power driver seat will not adjust forward or back.


My intuition tells me that the 6 way power seat track forward / reverse motor is bad. Sometimes you can replace just the one motor but most often a whole new power seat track is the only way to repair. It is not too bad to replace but the seat will have to be removed from the car and placed upside down to access the track assy. There are 2 bolts in the front of the seat and 2 bolts in the back of the seat that hold it down to the floorboard. Once it is loose you can rock the seat backwards to access and unplug the electrical connectors.
