When ever the steering wheel try’s to go to it preset position it moves up about a quarter inch and then stops all movement. If I try to move it with the button it moves more up until it wedges it self up to the dash and then it will stay there all day. When I come back in the morning it has move down to home position and it all starts over again. When it does work like it should and the wheel is right for driving if I try to move it will go up about a quarter inch and then goes down. It’s like there is a small amount of voltage somewhere to make it go up and then down. I have checked the switch on the steering column and I know it not that. Is there any way to adjust the home position?
thank you for any assistance.

 

How have you ruled out the switch?
The system just uses the detection of fixed resistor values that are identified and "read" by the control circuit in the instrument cluster that then sends commands to the motor and mode solenoids.
If you have some "resistance leakage" in the switch then the detection circuit will misinterpret the function selection.

If you want to bypass the switch to test the integrity of the detection circuitry along with the physical column position drive systems, then you just need to do the following:-

• Unplug the 8 way black plug to the switch assembly
• Then briefly touch a 1500 ohm (1K5 ohm) resistor between pins 1 (Yellow) and 3 (Black with red stripe) of the loom plug to simulate the up button press.
• Then change to using a 2200 ohm (2K2 ohm) resistor between pins 1 (Yellow) and 3 (Black with red stripe) of the loom plug to simulate the down button press.

If by applying these external resistors gives you normal control of the column vertical movement, then you just need to determine if the switch assembly has some resistance leakage internally within the switch, or if you have a some leakage or out of range resistor present on the switch sub assembly.

If the external resistors give you the same erratic column movement as the original switch, then you might be looking at a fault with the instrument cluster somehow misreading the input.
The Black 22 way connector to the instrument cluster receives the resistor inputs on pin 17 (Yellow wire) and pin 18 (Black/ Red stripe) should be a healthy low resistance to ground.
If the ground is weak (higher resistance when checked with a multi meter) then you need to check the grounding point (G31) located behind the passenger air bag, however I would expect you would have other instrument cluster oddities occurring with a bad ground.

 

One thing that normal is that it does move up a hintch before it regulates downwards . Even if you use the column regulator switch . The other way does the same on all of them

 

Will have to read this again . My 2003 xj8 does not move the column any more. Exchanged the switch since I had one lying around. To no avail

 

Petz,

If you hear the steering column motor working but getting no drive, then you might have the split nylon gear problem that occurs with the pedal box drive mechanism as well.

 

No noise fuse 49 or 48 passrnger side is ok but car has 372t km 2003 so no wonder.
was working til accerlertor pedal position sensor got cleaned
