1998 Z3 blowing headlamp fuses on high beam.

My 1998 z3 is blowing two headlamp fuses when I turn on my high beams. When it blows, I loose my headlights, tachometer, and fuel guage. However, the speedometer and parking lights continue to work?

Spark plug wires may be the cause. for cold damp start issues water is a conducter and will send spark directly to an engine ground not through spark plugs. also look for oil in spark plug wells this can also cause a misfire under certain conditions.

SOURCE: burned out headlight/bulb bmw 1991 325i 2dr

It's a bulb replacement. If it's anything similar to my Audi, there is a cover on the back of the headlight housing that you pop off. Then you can reach in, pull the wire connector off the bulb, and unclip a metal retainer over the bulb, and pull the bulb out. Installation of the new one is the reverse. Just be SURE not to touch the glass part of the bulb. Skin oils can cause a halogen bulb to burn very hot and burn out very quickly. If you do touch the glass, wipe it gently but thoroughly on a cotton cloth to clean it off before you install it.

2008 Saturn aura wont start after trying to put rt.low lowbeam replacement


On the inside of the lid is a diagram .
The headlamps may be turned ON 2 different ways. First, when the driver places the headlamp switch in the HEADLAMP position, for normal operation. Second, with the headlamp switch placed in the AUTO position, for automatic lamp control (ALC). During ALC, the headlamps will be OFF in daylight conditions, or low beam operation in low light conditions. Battery positive voltage is supplied to the low beam relay and the high beam relay in the underhood fuse block. When low beam headlamps are requested, the body control module (BCM) supplies ground to the coil side of the low beam relay. This activates the relay and the relay supplies voltage to the left hand low beam headlamp through the LH LOW BEAM fuse and to the right hand low beam headlamp through the RH LOW BEAM fuse. Ground for the left hand low beam headlamp is provided at G101. Ground for the right hand low beam headlamp is provided at G102. When high beam headlamps are requested, the body control module (BCM) supplies ground to the coil side of the high beam relay. This activates the relay and the relay supplies voltage to the left hand high beam headlamp through the LH HIGH BEAM fuse and to the right hand high beam headlamp through the RH HIGH BEAM fuse. Ground for the left hand high beam headlamp is provided at G101. Ground for the right hand high beam headlamp is provided at G102.

2007 chev sub head lights wont turn on


Do you know anything about automotive electronics ? Electronic control modules .
Headlamp ON/OFF control is determined by the body control module (BCM) by a signal on the headlamp switch on input circuit when the headlamp switch is in the HEAD position. When the headlamp switch is in the AUTO position, the BCM determines headlamps ON/OFF by the voltage from the ambient light sensor.
If the headlight switch is left in the ON position, the inadvertent power control feature will turn OFF the headlights approximately 10 minutes after the ignition switch is turned to the OFF position. If the driver places the headlight switch in the ON position after the ignition switch has been turned OFF, or if the ignition switch is in the ACCY position, the headlights will remain ON until turned OFF or the battery runs dead.
The high beam indicator is illuminated when the instrument cluster receives a GMLAN serial data message from the BCM that the high beams are illuminated.
High Beams
The high beam headlamps receive voltage from the headlamp high relay located in the underhood fuse block. The BCM controls the relay on the headlamp high beam relay control circuit. High beam control is determined by a signal on the headlamp dimmer switch signal circuit from the multifunction switch. When the headlamp dimmer switch signal circuit is grounded, the BCM grounds the headlamp high beam relay control circuit, illuminating the high beam headlamps. The right and left high beam circuits are independent and are fused independently in the underhood fuse block.
Low Beams - Standard
The low beam headlamps receive voltage from the headlamp low beam relay located in the underhood fuse block. The BCM controls the relay on the headlamp low beam relay control circuit. Low beam control is determined by a signal on the headlamp dimmer switch signal circuit from the multifunction switch. When the headlamp dimmer switch signal circuit is open, the BCM grounds the headlamp low beam relay control circuit, illuminating the low beam headlamps. The right and left low beam circuits are independent are fused independently in the underhood fuse block.

Hooking up a factory scan tool an checking DTC'S - diagnostic trouble codes would be the very first step in trouble shooting this problem .

Hi my name is Larry I have a 1998 Pontiac sunfire & my problem that I have is I have low beam. But no high beam.


It's probably the switch , but testing to know for sure is alwasy a good idea .

Where is the headlamp relay on a 2007 saturn ion


Are both low beams an high beams not working ? What engine does your car have ? Low beam relay only on 2.2 L .
On vehicles with manual headlamps, the LH HDLP and RH HDLP fuse in the fuse block - under hood, supply battery positive voltage to both low beam lamps and high beam lamps at all times. The low beam and high beam circuits continue through the fuse block - under hood, through the body control module (BCM), and to the headlamp switch. The low beam or high beam circuit then, depending on the position of the dimmer switch, continues through the headlamp switch. When the headlamp switch is placed in the ON position, it provides a ground path for the low beam or high beam lamps through G203. The low beam and high beam circuits are monitored by the BCM.
Is there B+ voltage at the headlamp fuse's ? Power runs from fuse through the head lamps to the dimmer switch through the head lamp switch to ground when turned on . If there is B+ voltage at the fuse ,check for voltage at the headlamp switch .

I blow the 15a fuse every time for tail, panel lights ,and dimmer,,every time I turn the headlights on


Headlamps and front parking lights/tail lights are usually fused separately on most modern vehicles.

The first position of the light switch would usually switch on the tail lights, number plate illumination, panel lights and front parking lights and the second position switches on the headlamps. From your description the fuse only blows when you select switch position 2 and the operation of switch position 1 is satisfactory.

If this is correct it would suggest a problem only with the headlamp circuits. This narrows the field somewhat which can be narrowed even further depending on whether the fuse blows only with the high beam or low beam. If it blows with both the fault must be common to both.
The use of a wiring diagram would be a tremendous help in tracing the fault but I suggest checking the bulbs first.

I have a 1998 Z3 1.9. The nearside (UK) sidelight does not come on, but the high beam does (same single element bulb). Checked sidelight fuses after replacing bulb... neither seems faulty. Any help as to...


hi.
the side light and the high beam will be different bulbs. they may appear to be the same, but if you look carefully, there is a smaller bulb, normally just below the main bulb. the sidelight will usually be a small 5watt bulb where the main beam bulb will be much larger, and anywhere between 45 and 65 watts. look for the smaller bulb and replace that first..

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 ).

Low beam headlamps wont turn on change bulbs and checked fuses and still wont come on.


did you check for a relay in your fuse panel? there should be a relay that controls your low beams and one for your high beams. check for that and then if high beams are working swap it with low beam relay. if your problem switches to low beams working and high beams not working replace the bad relay.

Replacement Bulbs


i believe on this car, low beams & fog lights use an HB4 and high beam uses an HB3. but, as bmw_tech_38 mentioned above, remove the old and it should be listed in the base.
