#45 of 48 Twilight Sentenel by pcjd388 Jul 26, 2009 (6:34 pm)
I have this stupid twilight sentenel on my 1997 buick lasabre and wondering where is the right spot to set it. It just has Min or Max and anywhere in between, but when we are like in the store parked under a light, the lights wont even come on when we drive into darkness unless we manually turn them on so I was wondering whats the best setting for the twilight sentenel or is the sensor for this going out and how do u know for sure if it is? Also what exactly do I take off to get to the sensor? Any help would be appreciated........ty Replies to this message: imidazol97 (Jul 27, 2009 6:08 am) pcjd388 (Jul 27, 2009 8:18 am)

Replying to: pcjd388 (Jul 26, 2009 6:34 pm) The twilight sentinel doesn't have anything to do with the headlights turning on automatically. It controls the length of time the lights stay on AFTER you turn off the key.   The turning the headlights on when the sensor doesn't get enough light to tell it it's daytime is a different operation. The sensor is buried down in the dash in the grooves for the defroster; if you look down from outside the windshield close to the left radio speaker grill, you'll see the dime-sized sensor for the headlights.   The one interaction the twilight slide switch has with the headlights is that it turns them off if you're in PARK and you slide the switch to the left. As soon as you shift out of PARK the headlights should come back on.   If the headlights aren't turning on automatically, I'd suggest using the regular buttons on the door instead. There is a connector for that sensor under the top of the dash, but I am not sure it's worth trying to get to it. Replies to this message: pcjd388 (Jul 27, 2009 8:18 am)

The headlights will turn off when i go under anything with bright light but wont come back on when the car enters a dark area, so I have to stop and messwith the lights to get them to come back on, rather not use the buttons on side of door so if you can suggest what to try or replace I would appreciate it

Had it checked by "auto zone" /" advanced auto"- one of these and he said map sensor.. should i replace it ? what if it the mass air flow? I would be willing to look it upand do it myself..cant afford it bring it to the shop. I have a 2001 buick lesabre.
