2001 Cadillac DTS. Left low beam headlight is not working. Have tried replacing bulb, relay and fuse. What else could it be?


Do you have a meter or test light so I can walk you through some diagnostics? If not try swaping the high and low beam relays. The relay may click when activated but that doesn't mean that the contacts are good inside the relay.

It is much easier to swap the relay if you don't have any test equipment. Sometimes the low beam relay is bad internally and replacing it solves the problem.

I have a 1995 Ford Explorer Limited and the high beams work but the low beams and fog lights do not, please help....


These trucks are known for bad multifuction switches.
the switch that i talk of is the signal switch , the handle is the switch, it bolts to side of steering column . this switch controls the signals and the headlights and high /low beams. the other thing is the headlight switch connector, the connector some times goes bad and starts to melt or just comes out of the connector. you will need to remove the cover to steering column, the screws are located under the bottom cover in holes. remove cover and check connector and then test for power if you have power going into switch but not coming out then switch is bad.

the last thing is to make sure the bulbs are good , make sure the headlight bulbs are good , and also the driving light bulbs, test for power at the connectors to those lights to.
You will need to do a little testing to find the problem.

When low beam headlight is on passenger sign is


Try this to eliminate new bulbs for both sides:
With a partner behind the wheel:
PULL out the bulbs one at a time. Keep them plugged in. While you are holding the bulb - have your partner click and HOLD the High Beam Selection. This causes the Low Beam and High Beam filaments to both go on and stay on.
Check both sides this way.
While the bulbs are out, look at the filaments that did not illuminate. Are they broken, bent, or have indications they are burnt out?
You can also change to bulbs (left to right, right to left) and recheck using the above method of holding the high beam selector and checking the filaments.

HOW DO I ADJUST THE LOW BEAM HEADLIGHTS TO SHINE


The adjustment screws/nuts should be located either on the top of the headlamp assembly, behind the headlamp assembly, or near the frame rail by the radiator support.

You will have vertical adjustment screws for each independent beam (separate highs and separate lows, but will be same screw if highs and lows are the same bulb). You may also have additional horizontal adjustment screws as well

Park your car on a level ground 30 feet from a wall and measure the height from the ground to the bulb and mark on a wall (do this for highs beams and low beams if the bulbs are separate, if highs and lows are the same bulb, only do it for the lows)

For Low Beams: If the headlights read VOR, then aim the brightest part or cutoff part just below the mark on the wall. If it says VOL or nothing, aim them 2 inches below the mark on the wall.

For High Beams (if separate from low beams): Aim the headlight directly at the line you marked on the wall.

Low beam not work !!


replace the headlight bulbs. Usually when the bulbs blow out the low beam blows out first, but the high beams still work. If you want and need both low and high beams to work then replace the headlight bulbs with brand new ones and I garauntee that both low and high beams will work
