twilight sentinal problem?
Like I've said before I had the car repainted,and I noticed the twilight sentinal doesnt go off in a short amount of time or at all (stand watching the car for 10min then I turn it off) what tells it to turn off? How can I test if whatever it is works? It turns on and off with the switch and has high and low beams. It also turns on with the twilight sentinal. Also I usually have it set for the minimum setting if that matters.
The timer module is dead. It's up under the dash near the light switch. There's a section in the service manual that details how to check it. It can be rebuilt for a price. If you elect to replace it, you must replace the timer and photocell together, as they are a matched set.
