Steering is striped - Cars & Trucks

Power steering temp sensor?

Sounds like you have striped out your steering box. I would start there as long as everything is hooked up as it should be.

check to see if the bolts aernt striped that holds the clampe that holds the ajustebel steering

Your steering box was not overhauled correctly. This is an indication that there is an internal leak in the spool valve. The spool valve seals probably were damaged by whoever assembled the unit.

you might have a bad worm gear ,its a gear for tighting the action of the steering wheel,i would have your tech look at it ,but most cases are to replace steering box.

The cab fuse panel, fuse #22 is only hot in the run position, and this is the white w/ violet stripe wire at the connector on the HVAC panel on the manual temp ( vs the EATC HVAC ).

The switch in any of the positions, powers the Brown w/ Orange stripe wire wire to the blower relay ( by the flasher in the relay block under the dash by the steering wheel column, usually covered in black tape from the factory ).

The blower relay powers the blower motor resistor, to know what speed to run at, this is powered from the engine fuse panel, fuse #105 ( 40A ).

If you do not have power on the white w/ violet stripe wire at the back of the HVAC switch panel, you need to meter both sides of fuse #22, to confirm power is through the fuse.

Ford Neutral Safety Switch; Ford Reverse Light Switch; Backup Light Switch.

The Neutral Safety Switch wires in my 1971 Ford F100 are orange with a blue stripe.
The Reverse, or Backup Light Switch wires are black with a red stripe.

There are two sets of two wires across this combined neutral safety and backup light switch, for a total of 4 wires. Photos are at the end of this post.

The switch for the 1971 Ford F100 pickup truck is the same as in many other years and models. For details, including parts numbers, see the following quote from an expert at Ford Truck Enthusiasts:

The neutral switch also controls the backup lights, and is the same 1967/77.

C7TZ-7A247-A .. Neutral/Backup Switch (Motorcraft SW-600)

There is no separate backup light switch..except on 1967/68 F350's.

Neutral switch location 1967/77:

The plastic half moon shaped neutral safety switch mounts on the outside lower portion of the steering column (NOT on the transmission!).

It's activated by an inverted Y shaped lever that snaps on the shift tube

The switch is also still available from Ford, but the website is down so I can't post the list & net prices. .

1978 is the FIRST year the F100/350's have the neutral switch mounted on the transmission. __________________

Driver side of the neutral / reverse switch showing the travel slot for the switch arm, the return tensioning spring, and the arm.


The front, steering wheel side of the neutral / reverse switch after removal from the steering column. The switch's two functions are actuated when the lever in the column moves the switch lever shown here to different positions as gears are selected.


The neutral switch is installed on the steering column near the firewall, with 5/8" bolts into the steering column (visible hole) and down column from a rectangular opening in the column housing. The actuating lever for the switch is attached to the gear shift shaft inside the housing; the lever is visibly protruding from the opening in this image.


Back of neutral / reverse switch, showing the wiring attachments. Black with red stripe is the backup light wiring, Orange with blue stripe is the neutral safety switch, it prevents starting in gears other than neutral & park.

pull the pully back off ,clean the shaft with emery cloth and also the the shaft hole in the pully then grease it up and try it again

My solution is as follows: Place a 1K-OHM resistor (Radio Shack Part # 271-1118) between the orange/white stripe wire (power) and the green/yellow stripe wire of the mullti-switch terminal block of the steering column. This provides the speeds - normal and intermittent speeds but not high wiper speed. Less than a $1 solution instead of the costly BTM replacement.
