Hi,welcome to fix ya. what happens is water gets in the headlight lens and migrates into the igniter for the HID bulb that is bolted to the bottom of the lens and shorts it out. you will need to replace the inverter/igniter and the lens to cure this problem.

My low beam headlights will not come on! My daylight running lights work during the day and I have high beams but at night I have nothing but high beams ???


Battery positive voltage (B+) is supplied through the LH underhood fuse block LCM/HDLP circuit breaker via CKT 242 (RED) at all times to the following components:
?€¢
Headlamp switch


?€¢
Lamp control module (LCM)


?€¢
Switch of the RH IP fuse block headlamp relay position J

When the headlamp switch is placed in the ON position, battery positive voltage (B+) is supplied via CKT 10 (YEL) to the coil of the headlamp relay position J. The coil is permanently grounded to G201 via CKT 1450 (BLK). The coil is energized and the contacts close providing battery positive voltage (B+) to the headlamp dimmer switch via CKT 1346 (LT BLU). When the headlamp dimmer switch is in the LOW position, battery positive voltage (B+) is supplied via CKT 12 (TAN) to the following components:
?€¢
Left low beam headlamp


?€¢
Right low beam headlamp The LCM provides battery positive voltage (B+) via CKT 1346 (LT BLU) through the headlamp dimmer switch to the headlamps under the following conditions:
?€¢
The ignition switch is in the RUN position.


?€¢
The ambient light sensor indicates darkness.

The lamp control module (LCM) monitors the ambient light conditions through the ambient light sensor. The ambient light sensor is a variable resistor whose resistance changes as the surrounding ambient light level changes. As the ambient light decreases, the resistance of the ambient light sensor increases. The LCM measures the resistance across the ambient light sensor and determines whether it is day or night.

Check for voltage at the connector. If voltage is present, you have a loose connection or broken defroster elements. If no voltage is present, you have a blown fuse or bad switch or wiring. A proper diagnosis is in order.

Headlight keeps blowing


Check the amps that are being drawn by the headlights. Compare that with what the bulb should be drawing using:
amps= watts / volts
I am going to guess its higher but not to the point of blowing the fuse for your lights. I would then start checking grounds.
Or, you used halogen bulbs and you touched the glass. I doubt they would both fail at the same time from that.

Only one headlight works


is the bulb burnt out? if not, i would say either a wire is faulty or the connection to the bulb socket is loose.

Headlight does not work. Not the bulbs. I have a 2006 Chevy Colorado and the passenger side headlamps went out. I replaced the bulbs which looked good (filaments where not broken) but the lamps are still...


Believe it or not you've actually got a fuse for the left and right headlight individually. Check both of these and also You've got a power control center under the hood(drivers side and I "think" another either behind the drivers seat or ucer the dash, and these fuses and relays are often repeated in both power centers(fuse and relay boxes). Grab your owners manual, which now is thicker than the King James bible,and begin your search. Also make sure,if it has one, that the ground from the headlight on that side , is good. Good luck my friend, Dana
