Mine was on the blink so I got a used one,now that;s gone and I'd to put the old one back in.
Anyone got one??? It's for a 1990 MK2 with the instrument panel dimmer under the switch, part no 323941531J

i havent got one...but they can usualy be cleaned if you carefully pop them apart....its normaly just 20 years of filth stopping it working

Never thought of that.

Basically after being on for a few minutes it knocks the lights from dip/full beam to side lights,would dirt cause that???

dismantled them both cleaned and then put them back together,give one a test on way oen road and no better than before,worked for about 2mins then off again.Put the original one back in all cleaned (amazing the amount of crap built upon terminals) so fingers crossed

Mine had this problem to.

So stripped it apart and grinded the years of crud and oxidization from the little metal parts inside and all works perfect now

Nope still not working,lights stay on for about 5mins and then go onto sidelights

might be a problem else where?

can you bridge the multiplug with some wire to see if it eliminates it? does the switch get hot?

When they go off,if I move the switch back slightly they'll come back on again,so the terminals at the back aren't makeing a strong enough connection.....just worn with age

Take it it's either off or on at speed 3,nothing in between?

Think the problem with that is that the connections aren't insulated and get corroded and break.
Replacement ones are about Â£25-30,but are insulated so a new one won't do it again.
In saying that mine has been like this for years and still ahve't replaced it!
