I have an Escort LX on a K plate, 1994 Mk4 I think. The problem is
that sidelights work, full beam works but main beam does not work at
all, actually gets dimmer switching from sidelights to main beam.
Changed the switch module (indicators, wipers, lights etc) behind the
steering wheel with another one picked up from a scrappie but same
problem. Tried a different relay from the same scrap car but didn't
have any effect. Any way of checking where the problem is? Is it
headlight switch, relay, or something else?
Happened while driving, had to drive home with a bodge job - one light
off, other on full beam, got halfway home before engine cut out
(electrical) so alternator wasn't working either, it was running on
battery until it conked out flat.
Anybody had this problem before? Is it common? What's the most likely
solution and the best way to figure out where the problem is?
