Okay here's the deal. My wife's headlights were running very dim so I decided to go buy new bulbs and change them. Went and got my bulbs and proceeded to change the driver's side light first. Plugged her in had my wife turn on the lights to check them. The light I just changed didn't turn on so I decided to change the other one. Changed the passenger side and had my wife turn on the lights again. Now both lights didn't work. I then swap the new bulbs out with the old ones and now it didn't turn on with thos either. I checked the fuses under the hood and the headlight fuse was good.
Suggestions?
My only thought was to get a voltmeter to check out the headlight plug in, the fuses box, and then maybe the headlight relays? (Are there such a thing? Are they easy to find?) I can't do anything right now because I live in a town house and its raining so I can't get at electrical stuff at the moment.

Get a test light and check for voltage at fuses and at the plug for the bulbs. Used in reverse you can check for ground presence.
There may be a common ground to all that is weak or broken,

Here’s a diagram showing your system.
You’ll notice that there is a relay and three fuses that protect the system. One 25 amp relay fuse, two 15 amp fuses; one for low beam and one for high beam.
Is there a possibility that you’ve purchased the wrong headlight bulbs?
Bulbs that are of to high wattage and caused the 15 amp fuses too burn out?
Make sure that the part numbers on the bulbs match the old bulbs.
Some aftermarket suppliers, offer high output bulbs; the numbers will be close with an extra suffix; showing that they are high amperage bulbs.
If this is the case; they may be just a little too much for your system?
When you turn on the headlight switch, can you hear the relay click?

Okay thank you all so much for your help. I've finally gotten a chance to take a look at this (its been raining for about 4 straight days now and since I don't have a garage I try not to dink with electronics in the rain). I'm getting a current from the main headlight fuse, but not the high or low beams. I've also checked the bulbs over and they have the exact same parts and numbers on them. DanD thanks for the diagram I mange to semi understand it  . If I have to take it to a garage so be it but I'm trying to figure this out on my own (while asking for substantial help from you guys). I just can't think of a reason why the high and low beems fuses aren't getting current and the main one is? It leads me to believe that I'm not getting good contact with the volt meter and that is what's screwing me.

Argento - Speaking of voltmeters/multimeters -- I seem to spend more time making sure the damn device is working on a couple of mine with the plug in, red and black wire leads and testing the tester on something known as to not screw ME up! LOL,

Let’s have a look at the diagram and see if we can make sense of it; then it might be easier for you to figure out what’s wrong with your system.
Power from the 25 amp relay fuse is sent to terminal 1 of the relay; that at this point is open to terminal 3.
Ignition on, power is sent to terminal 2 of the relay’s magnetic pull in coil.
When the headlight switch is turned on; it completes the circuit between terminals 2 & 4 too ground, creating a magnetic field, pulling the connection between terminals 1 & 3 closed.
Now power from terminal 3 of the relay goes to the high/low beam switch; when the switch is clicked to the low beam you should have power to and through the 15 amp low beam fuse. When the switch is clicked to high beam, power to the low beam fuse turns off and is sent to the high beam 15 amp fuse.
Hopefully this makes the diagram a little easier to understand?
One last thing about wiring diagrams, they are drawn showing the circuit in the rest position. You have to picture switches and relays turned on; too follow the path or current flow.
