The right side low beam head light stopped working. Instead of checking fuses, I bought the $95 replacement bulb. Replaced it and still no light. Checked the fuses then and found the fuse for it blown. I replaced it and STILL no light. I swapped the left side bulb to the right to see if it's a bad bulb and that wasn't it as it functioned properly in the left side. I ended up breaking the old bulb that I was using as a test (the functional one) and had to buy another. In short, I have two new bulbs that have both been tested on the left side and are proven to be working, two new fuses, and still no low beam on the right side. ALL of the other lights on the right side work. I don't know what/where to look at next. Thoughts or ideas? Thanks folks!!!

Im not sure if you have the HID lamps or not but if you do it sounds like a bad ballast

You may also have a bad earth

An easy way to check is to swap the headlamp housings
IE remove them and plug the left into the right cable and the right into the left cable.
You can do this without bolting them in

This will let you diagnose the lot in one step

If you don't have HID my bet is a bad earth but you can test the power at the plug. Dont attempt to test power in the HID lead as it is very high voltage and very very dangerous

Broken wire??Check voltage and ground at lamp connector.

 

DONT do that if you have HID lamps
The voltage is very dangerous and can kill

You can only do this if you have the standard bulbs
You can test up to the ballast on the HID's but it easier to swap lamp assembly's to test it all in one go

The ballast is the silver bit under the headlamp assembly.
I replaced my when it failed with the uprated cheaper unit (LAD5GL)

Full instructions on that are here

I do have HID lights. I will check the ballast as soon as I can. With my current work schedule, the weather, and the darkness (when I'm awake), seem to keep me from getting to these as soon as I'd like.I think I'm going to have to forego even more snooze time to tend to this. If I didn't have the fog lamps, I would have made this my top priority. They're not proper low beams, but they still shine on both sides so that others can see both sides when oncoming. Are there any other thoughts ya'll can think of while I'm doing this as I can only give so much time before I need to turn it over to the mechanics that will get the $$$ and figure it out where I couldn't (I don't know what's worse! lol).

 

ragman1171,

The best/easiest way is to take the bumper off
Thet will take you about 45mins the first time but less and less after you done it once

I can now take the bumper off in about 15mins

All you need to do is take off the lower screws from the undertray. you dont need to take the undertray off but its probally easier if you do the fisrt time.

The next step is the grill. This is just 2 more bolts

Finally the bumper. You just take off the bolts in the inner fender and the 2 under the bumper near he wheel. From this point give the bumper a good jank near the fender and it will come right off

I normally have the car on some ramps and have a towel under the bumper. The bumper will rotate down onto the towel. No need to remove any of the connectors

The headlamp then just comes off with 2 bolts

If you swap them left to right you should get the fault to swap sides
Assuming it does you can now swap the ballasts to confirm

I would go ahead an get a set of LAD5GL ballast first as you are going to need them at some point

I purchased 2 and swapped 1 in, so I still have a spare if and when the other one goes

Just follow the info above an the info in the LAD5GL swap
Id expect the wole job to take about 2 hours assuming it the forst time you have taken the bumper off

It's not something you really need to pay someone to do for you unless you can be bothered

cheers

Thanks for the info. I was planning to start whacking it apart this morning after I got home, but as I don't have the LAD5GL yet, I guess it would be best to locate a set first so they'll be on-hand if/when needed. Hopefully I can source them locally and get started right away, but if not, Off to eBay I go! lol I think it's necessary to mention that when I went to Advance Auto and O'Riley's Auto, they both came back with a D2S bulb and my headlights require the D1S (with the full size base) and I was told that the D1S is for the XKR and not the XJR. What do you make of it? Thanks again!

Jason

 

You need the D1S bulbs

Do yourself a favor and get quality bulbs only
IE Philips or Osram

No name Chinese ones only last months not years

Oh yeah, always replace both bulbs so the color matches
If you only replace one bulb (even with the same color temp) they wont be the same as the color changes over it lifespan

I changed from 3500K to osram 5500K d1s bulbs and at the same time replaced the turn and park bulbs with LED ones

The net effect is all the lights now match in color, both lamps are now a nice matching white

I also go my ballasts and led lamps from ebay

I bought the expensive ones! lol However, I don't know if I could be more livid than what I am now. The left side low beam no longer works now either. All fuses are working properly, I swapped the bulbs and still nothing from either side. When I press the "light" button on the FOB, I can hear the click from the fuse block in the engine compartment, but cannot figure out why both low beams went out... All the other lights on both sides work fine.

 

Sounds like its time for the ballasts to be done

Just confirming both HID lamps are now not working and you have replaced the bulbs

Just to be sure check the 2 power connections to the lamp assembly
There are 3 fuses for the HID

F2 (10A) in the rear fuse box powers the ballast
F8 and F9 (20A) in the front fuse box power the hid lamps

Cheers

Howdy,
Since the HID bulbs have been replaced with new ones, the right side never came back (upset to learn that it was only the fuse at first) on even after replacing the 20A fuse. After that, I checked the rear fuse and it was good as well. The left side still worked. I ran some errands Wednesday morning and the left still worked. Wed evening, they were both out. I need to check the rear again when I get home about 0730 EST. It's 0525 now. Gonna sting until I can get home and check it more. Hoping I'll find something simple, but not counting on it. Been nice driving the Durango again though. I've only taken short trips in her until the last couple days. Wish me luck!

This was my point in post#3.Always start with the simple stuff.

 

I was not able to locate the 3rd fuse for the ballasts. F8 & F9 were OK. I went through all the paperwork and locations 1-4 in the rear are not used on my car. I did find F43 blown which controls the rear cigar lighter. Replaced it.
