I've been working through a lot of the little things that don't work on this wagon. I'm down to just a few now.

1. Sunroof controls do nothing
2. Cruise Control does nothing
3. All of the interior lights but the driver's floor do not work

I've checked the fuses in the cabin and all are good.

Any ideas?

1. On my A6 if I hold the key turned to the lock position the windows and roof will close, does the 100 do the same? I was thinking if you crank the sunroof open a little and use the key to close to verify if the motor and electronics are good.

2. Cruise control, think a common fault was vacuum lines in the engine compartment but check out this <A HREF="http://forums.quattroworld.com/s4s6/msgs/211949.phtml">LINK</A> for additional issues.

3. The drivers foot light should is controlled the same as passanger foot. Does that come on?

John Hopkins

1) No, I think the sunroof on these is JUST the control on the roof.
2) I'll check that out. Thanks.
3) I need to check out the bulbs in the car, but I can't imagine that ALL but one of the interior bulbs are out.

According to diagram the 2 front footwell and 1 dome light are pretty much tied together but share a couple of contact points. Does the dome turn on with the switch to constant on but not with the door? The lighted vanity mirrors use the same 12V but different grounds, do they work?

John Hopkins

Actually, the passenger vanity light does work. None of the others with override switched do anything at any switch position though.

The center dome light when switched to constant on takes power (12V and Ground) from the black connector at connector station I. If you find this connection you can measure 12V from pin 1 to pin 3. Knowing the passenger vanity light works says the 12V should be good because it bridges from the center dome light. I would start there.

My 100 lets me close the sunroof with the key.

My 92 100s has the same issues. Sunroof and power windows basically work when they want to. I replaced the relay for the power windows didn't help
