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 |

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: http://www.classictruckshop.com/club...osch/relay.htm Mike 86/00 CJ7 Laredo, 33x9.5 BFG Muds, 'glass nose to tail in '00 88 Cherokee 235 BFG AT's "news.quicknet.nl" wrote: > > 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.
