Passenger side headlight (high & low beams) dont work. Thought it was the connector that plugs into the headlight. But found out after replacing the connector that it IS NOT. #22 fuse keeps blowing, thus my headlight wont work. During an attempt to get power to the headlight (by putting a 30 fuse in #22) the connector started smoking (FRIED). I have another connector BUT dont want to fry that one.
Not sure how to go about fixing the problem.
Please help!!
Thanks!

Pull the head light or remove the lens, then pull the reflector off/out (do not touch the shinny part if there is any shinny part left), then look at the wires behind the reflector to see if they are bare and touching each other.

Sounds like you have a short somewhere drawing a lot of current in the lighting circuit.
Does the fuse blow when the headlight switch is is set to off?
Check the earth connections, but most importantly, check the condition of the B+ cable in the main (kidney shaped) fuse box in front of the brake booster. There are plenty of references to this if you search on MVS, but quickly, remove, the cover and look down in the front of the fuse box and look at the nut on the cable that comes up there. If it is very dull or burnt looking, replace the B+ cable NOW. Worst case it can short out the fuse box and set the car on fire. Mainly affects 99/00 cars, but 98 can get the issue also.
The other issues would be the headlight relay, and the dip/headlight switch may have shorted out at the steering column.

The headlights in your car are operated by a switch and
the dimmer stalk by way of the headlight relay module.
All four of the headlight lamps have their own fuse that's
between the module and each lamp. Fuse 22 shows as the
one for the right-hand side low beam.
That means that it's a short somewhere between the module
in the fuse box up by the windshield and that low beam lamp.
More than likely, like the posts above suggest, you have a problem
inside the headlight bucket itself. But, it seems kinda weird that it's
affecting both high and low lamps. You may have a bad high beam
lamp - Just a thought.
If you unplug the connector to the whole headlight bucket,
does the fuse still blow? That answer should help you isolate
this problem. If you do need to pull the headlight, it's pretty
easy on this car. The ground is easy to check, too.
And even though you've probably got a handle on this by now,
It's a really bad idea ( Like "Car Burning Up" bad... ) to substitute
a larger fuse. EVER.
