Re: UNDER HOOD LIGHTS (midlifecrisis91)
First if you follow the wires down the hood you will see connectors at the bottom. Make sure they are hooked up. If they are, get a volt meter. Pull the bulbs out and check if you have power at the terminals.
If no power, stab the wires just below the housing and see if theres power there. If there is, then the mercury switches are bad and need to be replaced.
Keep us informed.

The fuse for these lights is NOT in the fuse block... it has it's own holder near the driver's headlight. Just follow the wires.
Many people pull this fuse, so it's just something to check.

Re: UNDER HOOD LIGHTS (ffvetteman)
Does anybody know the correct part number for the mercury switches, or another place to get them from? I spend 1/2 hour with my local GM parts guy and we came to the conclusion that they were discontinued.

Re: UNDER HOOD LIGHTS (mikey_vette)
Are the mercury switches mounted by the bulbs? and I can't find power anywhere when i put my meter to the plug. :crazy: I know this should be simple. :crazy: :crazy:

Re: UNDER HOOD LIGHTS (midlifecrisis91)
The mercury switches are little pill capsule shaped things that are up against one end of the bulb. At least they are on a 96. They are a fraction of the size of the bulbs
Did you check for power at the under hood light fuse in the lower front corner of the engine compartment?
It's unlikely that both mercury switches would be bad.

Re: UNDER HOOD LIGHTS (midlifecrisis91)
Try to never stab your wires with a test light when looking for power. I have seen corrosion run a long way up a wire from such little breaks in the insulation. If you MUST ever do this put a little dab of silicone over the hole. On these complex electronic vehicles big problems can be caused by such little details. They sell a switch kit to turn these light off and on as needed. This, of course could be easily rigged yourself, too. I don't like them on when I'm working on it in the shop. I just keep them unhooked at the connectors and made dummy weather-pack plugs to keep the dirt out.
