no low beam

mornin all. my wifes Lbug just failed rego for having no low beam. have check fuses relay all seem ok. Dont think both globes would have gone at same time....but thats my next move.............any suggestions???
just out of interest which is low beam fuse?
thanks in advance

Could be both low beam bulbs have gone at the same time - easiest place to start looking. (if this is the case, check the output voltage from your alternator - we have a fleet of cheap Jap hatches that are used as delivery cars, they have been known to have the regulator in the alternator fail and allow 30+ volts into the battery. Doesn't take long before the battery dies and the bulbs - particularly the headlights - blow)

Check also that the low beam fuse is making good contact in the fuse holder - crusty contacts can cause all sorts of strange effects!

Burnt contacts in the headlight relay will also cause both low beams to fail - what size bulbs are you using? Stock headlight relays can only handle lower wattage bulbs (around 50W a side), so if the car has been fitted with bulbs that are bigger than that then the relay could be fried.

Let us know what you find - could be a good reference for someone else with the same problem in the future....

Low beam is fuses 3 and 4

Down load wiring diagrams from here - there are a couple that are close

Power goes to the on/off dimmer switch on the RHS
Power then goes to fuses 3 and 4

My guess is that the switch has fried


If you have a multimeter see is you have juice on the live side
I reckon you wont

If you dont - take the cover strip off your dash and see if you have it up there.

If you are not comfortable - take it to a auto electrician

But download the wiring diagram to make his life easy

Hi

The ceramic fuses used in VWs are very prone to corrosion, the left low beam on my sons car has stopped working twice with a build up of corrosion even after cleaning.

Use a test light, not a multi meter (a multi meter will still show 12 volt at a high resistance connection) to check power at each fuse terminal end, then check power at the bulb connector, wiring is brown = earth, grey = parkers, yellow = low beam & white = high beam.

If you still have high beam its unlikely that the switch is the problem, is the relay clicking.

wow.............thanks guys, changed fuses, changed bulbs, relay is clicking, checked swith............have thrown the towel in dropped car at auto electrician and gone to pub!!! will let u know what the sparkie thinks. thanks for all your help

yeah the Yellow wire is Low Beam

so check its pushed on every where switch and fuse boxes both sides give them all a wriggle it may fix easy

abit late now but for anyone else facing this prob with both going lows going out at once check the yellow wire from the relay to the fuses hasnt come off
Lbug fuses boxes turn into a jungle behind once a few POs have added a few extra wires

i had this prob on my ute and turned out to be the relay, it clicked ok but just didnt hold .after scratching my head it turned out to be the relay some water had got in and buggered the small switch

On L bugs the relay sits underneath the drain tube from the air box

This tube cracks/leaks/whatever and i have had many relays full of water
