Headlights not working

[MackyM]

Not all the time, but sometimes I only have sidelights - then for no apparent reason the headlights come on - not a fuse in other words. Is this a common one? Is there a simple place to look for a fix. Thanks all.

Dodgy Bulbs, Dodgy relay unit or switch , check them all in that order!

on my jetta i had a side light out from time to time which in turn knocked out one side of the full beam??turned out to be just the bulb!it wasnt untill i replaced the side light once it had blown that i realised what was going on!

OK, will try (where's the relay?  )

[rubjonny]

There are no relays for the lights

First thing I'd do is swap in another headlight switch.  But beware the early MK2s had a different switch which will not work in your car, just check the switch you try has the same number of pins as the one fitted to your car

had exactly the same problem a while back. totally baffled me. in the end i found it was a loose connection on the back of the indicator switch/stalk. check that!

Thanks both - I will give it a go. Bulbs and headlight wiring are all fine I know that.
