This just started a little while ago. It used to do it for a couple times and then stop, but now it'* the other way around. I have to turn the lights on manually through the switch. Sometimes it will switch on after a while and the function will work and turn the lights on when shifted out of park and turn them off when shifted into park.
Is there a switch or something that is in the center counsole that triggers it? Is the light sensor not sensing that it is dark enough? Any information would be helpful. Thank you.

might be an electrical short, check the sensor, its in the defroster vent cover by the windshield on the pass side, just pull the little vent panel up and it should come right off, the twilight sentinel switch might be going bad too, mine is, if you touch it it acts like it went on crack and the lights flicker and you hear the module that controls the lights click really fast

That'* odd. Mine come on automatically as soon as it is dark outside, doesn't matter if it is in park or drive, or even started, as long as the key is on, the headlights turn on ( when it is dark)

It does not work when I switch the TS switch either. The TS switch does not have to be on for it to work in my car. It has worked in the past without the switch being in the on position.
I havent really checked anything yet. When it does work I can hear it "click" on when I put it into drive, but now it does not "click" when I do it. When I am driving sometimes I hear it "click" on.
Is there a way to check and see if it is the light sensor? Is there a switch on the gear lever that switches it on that I could check too?

Really? That might not be right. The auto-on headlights should be coming on when you pull it out of Park.

My twilight sentinel switch (from what I gather from the information my dad'* told me) is stuffed, apparently it got really really hot and gets really really hot so long as it'* installed. A junkyard hunt for a replacement yielded the surprise: All potential donor SSE'* had TS switches that were just as fried as mine.

So the switch goes bye bye (weight reduction!), and there'* manual-on headlights only.

By removing it, you also lose your daytime running lights.

mine are the same

Must be a Canadian-DRL install. My 91 has no DRL'* and the twilight comes on with ignition electricals. Not the gear shift.

Mine is a Canadian car since i live in Canada, LOL, and mine is not gear shift activated either.

Might I be a 1991 thing? :?

It'* a Canadian thing. There'* a unit that is green that plugs in under your dash near the steering colum. If it'* burned out then you'll probably loose your high beams. The cost of the part is approximately $300 but I don't know if it'* available anymore. I picked one up at a wreckers years ago therefore I don't know if there'* anymore around.

Good luck
