Head lights not working
Drove my 99 with lights on to get something to eat when got out started car turned switch to turn on the lights and they didn't pop up. Popped hood and they weren't on and I couldn't get them to come up, just didn't turn **** enough. Drove home with fog lights on. turned *** to get lights to come up and they wouldn't come on. I can pull back on the lever and get high beams to shine, but can't get head lights or high beams on in its constant on position just flash position.
So tail lights go on, dash lights go on and I can turn on the fog lights.
Any suggestions on what might be wrong.

Start by looking at the four, what I call....bump stops or tabs. There are two on the open headlight and two on a closed headlight and limit the open and close space of the headlight. The four are covered with a ruberized/plastic cap that gets worn or falls off completely.
If you can't find them, look in the search icon and try "headlight bump stop tabs".

My first guess is that your Multifunction switch is at the root of your problem. Normal headlights and "flash to pass" are separate switch contacts in the MF switch and both are fed from the same circuit breaker so it is not a problem with power input.
The MF switch outputs the headlights circuit separate from the other running lights using separate contacts in the MF switch.
If you know how to use a multimeter we can do some diagnostics to verify what the issue is.

I was thinking it was the switch. How can I go about testing it?

I would remove the connector for the MF switch. The "W" pin is power in. "L" is the low beam feed out and "K" is the high beam feed out.
I would use an ohmmeter to see if you can get continuity or not. Try measuring from W to L and W to K. Just make sure you set the switch for low or high bean as appropriate to take your readings.
If that does not show a problem then we need to see if we get continuity from L and K to their respective fuses in the engine fuse box.
Here is the connector. I have not scanned the second page but this shows you how to locate the pins. W is a Red wire, L is a Tan wire, and K is a Light Green wire which should help you ID the pins also.
Here is some info on MF switch access:

Let me know if you need anything else.
