Get 12v+ to the switch on the line side. If lights go on when switch is turned on , then you don't have power going to the switch. If however they don't go on, then put 12v+ on to the line side of the switch. If lights go on, then you definitely have a bad switch, replace it. If none of those actions get you lights. I would suspect a bad ground. Get some wire and attach one end of it to the negative battery terminal and use the other end to touch the metal part of the light assembly near the bulb socket. Make sure you don't touch the + part of the socket or wiring. If lights go on now, you have a bad ground connection and need to resecure ground wires that lead from and to light assembly.

Replaced alternator on sunfire now headlights wont work


Do the high beams work? How about he signal lights? seems to me a light relay (fuse) is gonzo. Basically, there is a light switch that is wired to a fuse/relay. From this fuse relay there is another wire that goes towards the headlights. Seeing both lights are not working chances are the fuse /relay is done for. Cheap and easy fix.

Its a German car and they are known for electrical problems. Your problem lies within the Drivers light assembly, check the voltage voming into the headlight socket with multimeter and see if there are any voltage spikes or drops, alternating.

Lowbeam headlights wont work, brake lights are out and check engine light is on...changed th dimmer switch, no luck


For the low beam problem, Swap relays 45 & 46 in the underhood fuse panel. Relay 46 is for the Low Beams. If that fixes the light, replace the relay that cam out of position 46.
Since the high mounted brake light is working, that indicates that the brake switch is good. You need to check the bulbs in the rear tail light assembly, if they are good, check fuse #34.

Low beam lights wont come on


First thing to do, is checking your fuse, then if fuse are ok, then check the relay, located under the hood by swtiching around with another relay of correct relay specs. If it works, then replace your relay, if not, check that relay if it works with another relay spot such as windows, and test the windows. If it is not the relay, then it could be your headlight lamps that is bad, check your rear tail lights to see if it comes on when you turn your headlights on, If the tail lights come on, then it is a good possibilty with the headlamps since the sorento are known to blow through head light bulb light crazy. I mean crazy. So maybe replace one side see if that would work, to really know for sure it's a headlight issue.

1994 Mercedes c280 high beams not working...


At first 1994 C280 high beams began to not connect regularly when stick pushed forward, then not at all. Drove high beams by pulling and holding stick back towards steering wheel until that stopped working, too. Shop said the turn signal switch was at fault-- had seen it many times before with W202; about $160 to replace. Haven't done it yet, but should be an easy fix?

I have a 1998 cavilier i have no low beams,fuses checked good


 I’m inclined to believe you have a headlight switch problem and here’s why. There are 2 fuses one for each of the headlights on the vehicle. For the daytime running lights (DRL) to operate the fuse and wiring to the right head light has to be good, because it supplies the power for both headlights in the DRL mode. The fuse and wiring for the left headlight has to be good because the DRL relay needs power from that fuse to operate. The DRL relay in turn provides a path through the left headlight and wiring to ground. When you pull back on the dimmer switch, you are activating the flash to pass circuit of the headlight switch assembly. Because the flash to pass mode works you then know that the high beam wiring and headlight bulbs are in good condition. This also tells you that the ground circuit for the headlight switch is good. In many newer vehicles, the headlight switch doesn't provide power to the lights. The headlight switch has now become the path to ground to complete the circuit. The headlight switch and the high/low beam dimmer control are one assembly so when you replace one you get the other free. Such a deal! My coffee bet is on the headlight switch assembly.
