Help! HID Xenon headlight kit removal, high beam only.

[89blackvette]

I have removed an HID Xenon headlight kit from my 1992 Corvette. It was a bright light only kit. I now have bright lights only and can not find any installation instruction to see how it was converted to have bright lights only. What should I check to get bright and dims working?? I removed the kit due to poor quality and some intermittent lighting problems looked like very low end kit. Thanks, this is my last electrical gremlin to repair on the car.

You removed the kit and reinstalled the factory sealed beam headlights?

Here's the schematic for a 90. The color of the wires should be the same as a 92
from the headlight switch to the bulbs.

12 volts from the headlight switch Yellow wire goes to the hi lo beam switch
which is mounted down at the middle of the steering column. When you toggle
the hi lo beam stalk that's the switch that makes the click sound.

At the factory bulb socket headlight plug are three pins.
Tan wire is for lo beams
Light Green wire is for hi beams.
Black wire is ground.

When in lo beam you should have 12 volts on the Tan wire.
When in hi beam you should have 12 volts on the Light Green wire.'

HID headlight removal

ECSS thanks for the reply. Yes I removed the kit and installed the stock headlights. What I need to know is how it was changed to have blights only so I can undo that. I hear and feel the dimmer switch clicking but have bright only with bright indicator light on in the dash. I was hoping someone here had installed or removed one of these kits and have that information. I have looked on the internet and can not find installation instructions. Again thanks for the reply. I will crawl under the dash tomorrow night after work and see if I can discover it.

I hear and feel the dimmer switch clicking but have bright only with bright indicator light on in the dash. I was hoping someone here had installed or removed one of these kits and have that information.

Here's a picture of the hi lo switch. It's mounted on the left side middle of the steering column.
The switch is circled in red. The yellow arrow points to the rod that runs up the steering
column and is what activates the switch when you pull up on the stalk.

The electrical plug at the switch has 3 wires. Yellow is 12 volts.
For hi beams the Yellow wire is connected to the Light Green wire.
For lo beams the Yellow wire is connected to the Tan wire.

Only way you can have hi beams only is a bad switch, (easily checked with an ohm meter) misadjusted switch or the plug is disonnected and some one has jumpered the Yellow wire to the
Light Green wire.

If you notice in the picture the switch can be adjusted by loosening a nut and a bolt and
moved up or down.

The ignition switch is also held in place by the same fasteners and is on the
passenger side of the column so if you adjust the hi lo switch make sure you don't move
the ignition switch.

If you remove/replace the switch, make sure you tape the rod that actives the switch
against the steering column while the switch is removed. Once the switch is removed there
is nothing holding the actuator rod in position. If that rod falls down away from the steering column you will have a difficult tiime putting it back in position.

I went under the dash and you will not believe what I found !!! They left the original dimmer switch intact and attached to the steering column and simply used another dimmer switch with wiring plugged into it and set for bright lights. Connected wiring to the original dimmer switch and it works great. Plus side is I now have a new dimmer switch spare for free. Got bright and dims now just like Chevrolet wanted it. Thank you for the replies, perhaps I should have just looked but I am one of those guys that does research before I touch anything. Again thanks I have ALWAYS gotten informative timely replies accurate replies on this board. One more time THANKS!!

evss Do you happen to know where the light green wire comes out of the dimmer switch and bundles? 1 of the wires goes to the high beam indicator, 1 wire goes to the high beams and 1 goes to the fog relay.

The connection I'am trying to find is S208 in the FSM.

From the hi beam switch the Light green wire goes to the following.

Both headlight bulbs. For unknown reasons the Light green wire changes to a tan wire
then back to a Light green for the passenger side headlight. For the driver side it's always
stays a Light green colored wire.

Light green wire goes to the fog lamp relay to disable the fog lamps when hi beams are on.

Light green wire goes to the CCM which turns on or off the hi beam indicator.

Only description for splice S208 is Instrument Panel harness near Headlight Switch break out.

Thanks

I'm going to find that connection, and pull out the light green wire going to the fog relay and ground it. That way the fog lights will stay on even while on bright. I think it may be easier than removing the hush panel on the passenger side and grounding it at the relay itself.
