???????? ive never seen that.i dont have that dim switch only the 3 selection switch
might be on to something...dmonkee does your car have the stealth button?If this is a 9c1, look for the "stealth" light switch. under the radio. Same behavior on my 1A2.
try turning on the exterior lights then playing with the swithcyeah i have the steath switch when i hit it, it does nothing when the lights are on but it turns the digi dash off when the lights are off
do you have one? because if you have the stealth switch, you shouldn't have a twightlight switch unless it was added later. but somthing could be fulty in your dimmer switch. the Twighlight sentinal is meant to turn your headlights on automaticaly when the sun goes down.im hearing i may need a new Twighlight sentinal swich
