Does anyone know where the on/off switch is located for the underhood lamp of a '99 4Dr 2wd? Mine had not worked for a long time until I replaced the bulb a few days ago and now it will only turn off when I disconnect it. I know some of the other body styles had the lamps with mercury switches. Mine is the old style (see attached photo).

find the tilt switch, open it up and clean the contacts. yours may use a pressure switch upon the core support by one of the hood hight adjusters..
Thanks for the quick reply. I just came in from examining the entire hood area and I cannot find the switch. I pulled all the points made of rubber where the hood contacts the body and no switch. I have closely examined the hinges for the hood and cannot find any there either. Any other ideas which might help?

Uh yeah, there is no switch. turn it off by removing its bulb. it runs off the always hot horn fuse.
The switch is in the fixture.
Since I could not find a pressure switch in the hood area, I removed the bulb fixture and disassembled it. The fixture itself contains the switch. I followed the suggestions of ezdaar and cleaned the contacts and made sure the metal barrell would move freely inside the fixture. Now it all works fine. Attached is photo of disassembled fixture. Thanks, Doug.

Alright maybe I missed something but does not look like a switch.
The barrell shaped aluminum piece forms the contact between the bulb and the power wire. It slides within the plastic casing. As the hood is lifted, it forms a contact between the bulb and the orange power wire (pictured). As the hood is closed, it slides away from the power wire shutting off the light. I guess you could call it a gravity switch. Fragile design which is easily compromised by a little dirt.
This thread does a better job of showing how the tilt switch works.
