High beam lights don't work

Those lights are on different circuits. The high and low beam lights are powered thru the headlight switch, the turn signals, brake, and hazards go thru the turn signal switch.
I would want to know if each circuit has power at the switch that controls it.

replace light bulb{don't touch the glass part of the light bulb} or they will last only a month or less.

headlight relay or switch

Are you getting power in and out of the dimmer switch for both high and low circuits ?

ck for power to bulbs ck fuses ck switch

Could be the dimmer switch.

If your high beams work and your low beams do not work... try changing the light bulbs first. The low beams can burn out and the high beams still work.

I'm not sure exactly what your problem is. When you "click" your lights to low beam, your high beams should not work. But if your low beams work when you "click" them on, but your high beams don't work when you "click" them on, you either have a blown fuse, bad relay or high beam elements burned out on both lamps. (Not so unusual) Possibly a bad "dimmer" stalk switch or bad wiring, too, but a little less likely.

ok, first ,, check all the bulbs again, and *** make sure that your hands never touch the actual bulb, these lights will turn the oils from your hands into cooking grease when it comes to these bulbs and cause them to blow out much to early on in their life span, , next,, Pull the light switch ( high beam switch towards you for a quick flash of the head light high beams,, if this doesn't make the high beams come on, your problem is going to be in the switch itself ( what your calling the high beam/turn signal lever) before going to that extreme though,, if you have a junk yard near you, go pull one of the relays off a junked vehicle, and stab it into your system one at a time, it could be something as simple as a relay heating up and disconnecting prematurely due to heat ,, if you don't have a junk yard that you can grab a relay,, here is a link that shows how to check them, But its time consuming http://www.youtube.com/watch?v=C8t25GjZ6i4&NR=1

wire a relay parallel into the low beam light power wires
run a fuse controlled wire from the battery to the relay
when in low beam the relay activates to turn on the lights
when in high beam there is no power to activate the relay so the lights go out
If you read the regulation carefully , you will see that is also required to have a separate on/off switch for the lights
