Question about 1989 Ford F 150

1989 F150 ignition cylinder switch

When starting my F150, the cylinder switch goes from the start position and on the return to the run position it shuts off. I have replaced the cylinder switch with the same results. The key is in the run position but the engine turns off. I can start it very carefully, and manually movr the key to where the motor still runs. But the least little movement of the key and the engine shut off.

Remove the ignition switch cylinder and inspect the contacts in the column. Look for dark spots, scratches, excessive scuffing. My guess is that cleaning the contacts with a little tiny piece of sandpaper and perhaps bending them out a little (so there is more pressure between the contacts when you reinstall the cyclinder) will cure the problem.

When the key is in the ignition, It won't go back to the Run position from the start position causing a grinding sound to happen.


Sounds like a bad spring in the ignition cylinder or the ignition switch itself isn't returning the key and switch to the Run position as it should. Most any auto repair facility can check and replace the switch for you. Note that the ignition lock cylinder (where you put the key in and turn) is NOT the switch. The switch is connected by a linkage up to the lock cylinder. The cylinder moved the linkage and the linkage moves the switch.

It would not hurt to squirt some WD-40 or other spray lubricant in the lock cylinder to see if that resolves the problem. Don't use lithium grease though, only use a light lubricating oil spray, and don't go crazy with it. Just a couple of squirts.

I' m not mechanic, but rather thinker. If cylinder #1 is the only variable here, them it might be the join of the cylinder/ piston that is defective or has more play! Hope you can find prompt solution! Cheers. Robert Calgary, AB

The car starts fine but the key does not return to the "On" position after the engine starts.


I would say the switch and not the lock cylinder. The switch should have a spring to return the lock back to on.

Your ignition switch is made up of two parts the switch itself and the cylinder. You stated you replaced the cylinder but it's the switch (housing that cylinder goes into) that needs to be replaced.

Ford f150 the windows,radio & wipers don't work when the motor is runing then i turn it off & place the key in the back position of the switch they work


Might want to remove the tumbler, and check it for obstructions, or dirt in the grease.

One quick test for this would be :

Start the truck as normal. Check the radio, if it is off, slightly turn the key backwards towards the off position, only moving the key 1 or 2 mm. It could be the key is not returning from the start position correctly.

To check the tumbler :
Look on the bottom of the steering wheel cover. There should be 4 holes, but only 3 screws. The empty hole should be by the ignition switch.

1 Insert the ignition key and turn to the RUN position.

2 Insert a punch in the access hole of the steering column and press the release tab while pulling out the ignition switch lock cylinder.

Once you have it out, you should be able to look inside the tumbler path, to see if there are any obstructions, or grease & dirt build up.
This is also the same way to remove the key in ignition warning chime. It should be a tab on the end of the tumbler ( mine was broken, left in the tumbler path )
Pry the clip down, and push the tab off the rear of the ignition switch lock.

Putting it back is a case of pushing the same punch in the hole, insert the switch lock cylinder back in, release the punch, and cycle the key to the off position.

the ignition switch is an electrical part. The lock cylinder is whre the key goes and it activates the ignition switch. If you pulled the lock cylinder out, you could operate the car with a screwdriver.
Either you have damaged the ignition switch where the lock cylinder goes into it, or the lock cylinder is damaged where it fits into the ignition switch.

Section 11-05: Steering Column Switches 1996 Taurus, Sable Workshop Manual
DESCRIPTION AND OPERATION Ignition Switch The ignition switch (11572), which is mounted on the steering actuator housing (3F723), operates in the following manner:
  • The ignition switch is cycled through rotation of the ignition switch lock cylinder (11582) through a pin which is part of the ignition switch.
  • The ignition switch lock cylinder also controls the mechanism which provides a positive lock for the transaxle linkage and the steering system.
  • The locking mechanism is located in the steering column housing.
The ignition switch lock cylinder positions are:
  • ACC
  • LOCK
  • OFF
  • RUN
  • START
The key can be removed from the ignition switch lock cylinder with the column-shift transaxle only when the shift lever is in PARK position and the key is in LOCK position.
  • The ACC position operates while the steering and transaxle remain locked.
  • The engine shuts off when the key is turned to the OFF position without locking the steering or transaxle.
Blade Type
The ignition switch has blade-type terminals that engage with one multiple connector. The multiple connector is secured to the ignition switch by an integral connector fastener.
