Automatic Seat Positioner and Steering Wheel Tilt malfunction

[Razi]

Hello everyone.Our Q has been running well for all this time, with a few little glitches here and there.

A new one has popped up and the steering wheel does not tilt up.I noticed that the lights on buttons "1" and key "2" on the Seat Control panel flashes, whether or not the key is in the ignition.Then I noticed that the Automatic Seat Positioner is malfunctioning.So I played with all the seat controls and steering wheel control, found that the tilt does not work.I believe the ASP does not work since the steering wheel tilt does not work.

So:All seat adjustments work.Steering wheel telescopes, but does not tilt.Buttons "1" and "2" blink.

So here is what happens:-When I move the steering control switch up and down for tilt, I hear no sounds, no clicking. Telescoping works fine.-The lights on butttons "1" and "2" on the seat control panel blink non-stop.-The steering wheel has tilted up and down fine up until now, so this makes me think it is could be the tilting sensor.

My questions and ideas:-Since there is no clicking sound, does that mean the tilting motor is malfunctioning?-Maybe the switch sends no power to the motor if it senses that the tilt sensor is malfunctioning?-I'm leaning towards the idea that the tilt sensor is broken, and the control panel senses that and lets me know by blinking the 2 keys and preventing me from tilting the steering wheel.-Also, if the motor is dead or dieing, I expect to hear some type or click or whining from the motor. I'm no electrical guru so I'm not sure.-Is there a way to test the tilt sensor or motor?

Post feels a little lengthy.Thank you for any input, and for reading this post.

The drive positioner system uses linear potentiometers to for positioning info. It's possible that the the pot used for wheel tilt is bad. It may just need cleaning. I've never messed with the ADP system, but the steering column surround is simple to disassemble. Crack it open (I think 3 screws underneath, then squeeze the sides to separate the simple clips) and take a look. Try cleaning the pot and if that doesn't work, replace it.

It's also possible that the switch is bad. The switch is very easy to replace once the column surround has been removed.

I'm assuming this is a G50?

Ah yes, G50. Sorry I forgot to specify that.

I took it apart last night to see if anything was loose, didn't see anything out of place.

I will take it apart and take a more thorough look at it tomorrow when I have time.
