Headlights not working on XJ 87
Gents,
I have a 87 XJ 4.0, the four headlight wagoneer model.
A few days ago I replaced my upper headlights with new
H4 bulbs, same specs same brand.
After that when I used my lower "big" headlights, after a few minutes
all the headlights completely died. I switched the handle on the steering
columne to off and the normal lights would come up again.
But the third time I tried this, I noticed a burning smell in the interior.
I left
the big lights off. The next day the headlights would not function at all.
Now I have checked all the fuses and the bulbs, but there seems to be no
fuse for the
headlights on this model. I found a relay on the left front in the engine
compartment,
but changing this did not help.
I suspect the headlight switch to be bad, but all other functions of the
switch seem to work fine.
Can anyone please tell me if there is a headlight relay and where it is, or
might there
be another fuse which I cannot find? Please help.
Rodger

Grab a switch from the wrecker, if that doesn't solve it, it could be the
high beam selector.

Re: Headlights not working on XJ 87
There is no headlight relay that I know of, but you 'do' need one to run
H4 bulbs or you 'will' fry the headlight switch.
The stock headlight switch can't even handle 2 H4 bulbs, let along 4 of
them.
Once you replace the headlight switch and likely the wiring harness plug
for it too, you should add a relay and just use the headlight switch for
the relay trigger. Here is a good site on wiring in a relay:
