High Beams not working

Alright, so I've done a lot of poking around and searching but I can't seem to find a fix.

My high beams quit working a while ago and I can't seem to figure out why. Bulbs have been replaced and I just replaced the multifunction switch on the column today. When I flip the high beams on, the blue indicator light comes on, but not the actual lights. If I pull back on the stalk sometimes the low beams come on. To further compound things, if I have my fog lamps on and try to use the highs, it instantly blows the 15A fuse for the fog lights. I'm wondering if I haven't blown a fusible link somewhere. I do have an aftermarket H4 kit, but the wattage is stock - although I have ran some pretty high wattage bulbs in the past. When the high beams quit working, stock 55/60 bulbs were in.


It's a 99 XJ with a 4.0 and AW4, although I doubt that's irrelevant in this case..

Any help would be appreciated. Thanks guys!

The commonality between the high beams and the fog lights is that the fog relay grounds its coil through the high beam filament... I have no idea if that is actually your problem, but it's worth pulling the relay and seeing what happens.

I forgot to mention that - thank you. I did pull the fog lamp relay (the actual relay under the hood) and tried the high beams - nothing. It did not make any difference.

Tried cleaning the connectors in the pigtails today. No results. I really have no idea where to look next. I'm wondering if my headlight switch is the culprit, but I don't want to throw any more parts at it if I know they aren't gonna fix it...

Anybody?

Simple, find and fix the damaged wires/short circuit that blows the fuse. The tough part is finding, and no one can remote diagnose this problem for you.

Dig into it with a logical and methodical diagnostic process. Inspect and test both wire circuits. Or, it might be easier to pull a complete used wire harness from a junkyard XJ.

yeah, what he said. I bet you I could find the problem, but teaching someone to troubleshot electrics over the interwebs is difficult.

Also, it's such a PITA that it's so hard to find a good wiring diagram for an XJ. (if anyone knows where to download one, let me know...! I have all the FSM books save for the big one, unfortunately haven't found one for a good price yet.)

Use an ohm meter, power off, and see if one of the hot wires at the bulb is partly grounded.
