My switch to turn my high beams on never worked, so i would have to hold the lever towards me as i drove. last night though, the high beams turned on and now they wont turn off. not even if i turn the car off. is there any way to fix this without disconnecting the battery every time i want to turn the lights off or spending three hundred dollars for the new part?

Low Beam System Operation
The headlamps may be turned on two different ways. First, when the end of the of the turn signal/headlamp switch lever is turned to the second detent position, the headlamps will illuminate. A ground signal is provided to the DRL control module. The module then provides a ground path to the coils of the HLP relay. Since the head relay is provided with battery voltage to both the contacts and the coil, the coil becomes energized and closes the contacts providing voltage to the DIM relay. With voltage and ground provided, the low beam lamps light. Second, with the switch in the OFF position, for automatic lamp control (ALC). During ALC the headlamps will be in one of the following modes of operation:
• Daytime running lamp (DRL) operation in daylight conditions, refer to DRL below for the operation of the circuit.
• Low beam headlamp operation in low light conditions. When the ambient light sensor senses a low light condition for approximately 15 seconds, it will cancel DRL operation and turn on the headlamps at 100 percent intensity. A path to ground is provided to the coil of the HLP relay. With a direct path to ground provided to the headlamps though the DRL control module, the headlamps will light at 100 percent intensity.
High Beam System Operation
The high-beam headlamp operation is controlled using the turn signal/headlamp switch lever on the steering column. In order to change headlamp operation from low-beam to high-beam, push the switch lever toward the instrument panel (until the detent is felt) and release. With the switch lever in the high beam position, ground is provided to the DRL control module through the turn signal/headlamp switch and splice pack 200 to G200. The DRL control module provides a ground to the coil of the dimmer relay. Since voltage is being applied to the dimmer relay coil, it becomes energized. Voltage is then applied through the closed contacts of the dimmer relay and the to the high beam lamps in the headlamps. Since ground is provided to the headlamps through the closed contacts of the energized DIM relay, the high beam lamps light. The high-beam indicator (blue) in the instrument cluster will light during high-beam headlamp operation. In order to change headlamp operation back to low-beam operation, pull the turn signal switch lever toward the driver (until the detent is felt) and release.Your best bet , take it to a qualified repair shop.

Problem is in the switch ,replace.

To clarify, when you pull the turn signal lever towards you, the high beam lights will come on only as long as you hold the lever up. This is the flash to pass feature.
To switch the headlights from low beam to high beam, you push down on the lever towards the dash. Then the high beam lights and the blue indicator light should stay on.

headlight relay or switch

Its sounds like the either the headlamp switch or the dimmer switch. The dimmer switch may be separate from the multi-function lever or you may have to get the whole thing replaced.

iTS A FAULTY HEADLIGHT SWITCH

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

You need a new Multi Function Switch. The lever for High Beam And Low Beam and Left Turn and Right turn. ( Multi Function Switch )

mostly wires problem but it that will happen again try to check your bulb alright.thanks

pull on the signal lever toward you (ceter position). the signal lever controls the head lights either high beam or low beam. if you pull on the signal lever toward you again, you will have high beam temporarily. and if you push the signal lever towards the front, you will have the high beam locked.
