So amidst my P0705 CIL code and a new battery, my XJ has endured the first legit snowfall of the winter. The heat, the running lights, the start up, all of it works fine--Hell, even the CIL disappeared after I threw some Seafoam into the gas tank two days ago. Anyway, I start my ride up and let it warm for several minutes. I come back out, hop in, turn on the lights...and notice that my right headlight has gone out. Driving home, I discover that both brights work fine, but the right standard headlight won't wake up.

All the other lights seem to work fine (even the reverse lights, despite the P0705 code). Has the cold/snow killed something? It's been hovering around 20 degrees for days now with no problems but come the first heavy snowfall and for some reason the light just won't respond. Any thoughts?

Also, the CIL has vanished but I'm still feeling a lack of pickup/overdrive when I hit the interstate. Is this common?

Thanks and stay warm, Jeep peeps,
J

 

Sounds like just a burnt bulb.

 

So the brights have their own bulbs? I feel kind of retarded. :\

 

yo man i had the same problem one day my left low beam went out but the high was workin..then the right high went out but the right low beam was still workin..it happen right around the time when the temp was in the 30s so idk if thats it but good luck..you just gotta replace the light...and im not sure if you know or not but u gotta replace the hole light its not just a bulb

 

If there are the stock lights then you replace the whole light. Its easy to do and they dont cost that much

 

Grounding strap.

 

Gently tap/thump the lamp or wiggle the connector if you can. If any change then maybe a dirty/oxidized connection...

 

agreed probably just a broken low beam filament, but may be a corroded connector. Get a new bulb for that side (h4 size) and some dielectric grease to pack the connector with before plugging it back in. You should be good to go!

 

I checked Autozone's website and the headlamps run anywhere between $10 and $20, which is odd because most of what I found on eBay was in the $50-80 range.

 

It sounds like your low beam filament is burnt out. Try replacing that headlight with a Sylvania Silverstar. The difference is amazing.

 

Not sure which Xj your talking about that came with H4's, but every other one I know of came with sealed beam housings where the bulbs are not changable. You need aftermarket housings for H4.

Change the bulb. I cant belive this actually made it on to the forum....
I recomend silverstar............

 

Roger that, peeps. Thanks for the advice. I'll be changing them on Thursday...assuming the weather doesn't act out again here in Nashville.

 

ah my bad for some reason i thought the factory sealed beams were H4 size also. Haven't bought those in years

 

I'm here in Nashville also. Whether is going to get really bad according to the news. Be safe.

 

Yeah, thank you, Ken. I'm thinking of picking the parts up tomorrow while I'm out and just lying low until the weekend. Unfortunately, I work nights so it's going to be a tricky few miles back and forth from work, as far as dodging the fuzz goes.
