Question about 2007 Pontiac Grand Prix GXP Sedan

1 Answer

Low beams not working. Brights, fog, turn, and brake lights all fine. Checked fuses under hood, all fine. Have not yet checked bulbs. Any ideas why both would stop working at the same time?

    Found the answer to this problem It is a relay in the fuse box under the hood. Part#15016745. Black, square relay. Dealership told me it's a common thing to have them go bad once in a while. You can get them from a parts store, but most do not stock. Unless you can go a week without headlights, I suggest biting the bulet like I di, and going to your dealership to purchase. Mine cost me $43, but it varies by dealership. Just buy and install yourself.

I have a 2004 Mitsubishi endeavor dim lights won't work brights do


If both low beams don't work, check for a low-beam fuse. Sometimes they hide them under the hood. If it's just one low beam, it may be the plug on the bulb or wiring to the bulb, even a bad ground wire to the bad bulb. Look for crispy wires or dark bulb terminals. Sometimes the terminals or plug will have green stuff on it, similar to what you find on the (+) terminal of the battery. They sell bulb terminal grease to help prevent this. Toodles.

After jump starting 2006 Z4 BMW headlight low beams don't work checked fuses in glove compartment and under hood all seemed to be ok is there a relay, what do i do now


If the lights are switched then the switch controls a rely all lights are switched on bmw. Can use fog lights temporarily. Find rely test with continuity meter when on, disconnect lights first, then turn on lights switch, check for 12v at light bulb terms, if 12v then bulbs bad, if not relay is bad, test with continuity meter, rely should read 0 ohms when lights switched on, infinite open circuit when switched off. If lights work in manual switch pos then solar sensor bad.

High beam indicator comes on with fog lights


Could your Mazda have daytime running lights? If you checked all fuses, did that include the three in the joint box?

There is an auto light-off control module that is central to all functions you describe. It is assumed that you would only turn on the fog lights with headlights on and set for high beam. If you set the headlight switch to LOW, the module closes the headlight relay to turn on the low beams. If you then turn the headlight switch to HIGH, the module turns on the high beams and allows you to turn on the FOG LIGHT switch, closing the fog light relay and turning on the fog lights. Since this sequence is not working, I suggest checking both high beam lamps as both could be burned out. Other possibilities are a defective headlight switch or the module

98 ford lariat. Headlights stopped working. running lights come on and brake lights and turn signals. checked all fuses under dash and under hood, pulled out headlight switch and it looks fine. note only...


Is this both the high beams and low beams that do not work ?

If you checked all 3 fuses with a meter ( with the headlamp in Low position for both low beam fuses or in high for the high beam fuse ), the next items to test are the MFS ( MultiFunction Switch ) and the main headlamp switch ( test not look at it ).

I have a 2000 saturn ls sedan. My headlights are no longer working. All other lights are functioning fine. Tail lights, brake lights, turn signals.....all fine. Its just that when I turn my headlights on...


it is most likely a blown fuse,the fuse box is usually under the hood also check the low beam relay,it may also be in the fuse box,if you have a test light see if there is any power to the low beam at the bulbs,if they are H4 bulbs it is the center terminal,also check for any loose wires or connector plugs,,,,,hope this helps......cheers

Headlites went out, is this a bulb issue...


It sounds to me that if you checked all the fuses and they are fine that it could be the headlight switch needs to be replaced or very uncommon but possible that both low beam bulbs blew at the same time and need replacement.
