Morning all, I have a 2005 GT 1.9 JTD that I have owned for about 5 years and it is fitted with the standard Xenon factory headlights.
I have always had problems with the passenger side (non xenon) sidelight failing all too regularly. It normally lasts for about 6-12 months but then needs replacing. This means I regularly have to access the passenger side light cluster (never an easy job), however I have never had any problems with the main dipped xenon headlight bulb until now
Luckily being the passenger side Xenon I have just enough room to inspect the bulb, remove it, and the black box it attaches to, and to also test the circuitry as best I can. I cannot see any visible problem with the Xenon bulb itself, however I seem to be getting no electrical feed from the power supply cable that plugs into the black box attached to the bulb holder.
Hope this makes sense, to anyone owning the same factory Xenons that is? I'm thinking I need a new ballast, as the electrical feed coming to the black box is coming up from the ballast, right? I have also read that if water gets into the light cluster housing then it can drop down into the ballast connectors, frying the circuitry?
There was no sign of moisture in the light housing when I took it off however given the amount of time the housing has been accessed it is possible that damp may have got in? I have also had the car off the road and sat idle for 8 weeks, so this may have done it no good at all. Thinking about it, the main beam Xenon WAS fine before the car had its enforced time off?
I am aware that the next step is to drop the bumper however I want to have ordered the parts before doing so. Have ordered a new bulb, as they are pretty cheap now (£9) compared to the £100 I had heard them quoted in the past!
I have seen second hand ballasts on fleabay for around £129 and also new 'repair kits' like this one, which seem to be a ballast and all the wiring
Does anyone have any better ideas, before I go buying more parts, or do you think I'm thinking down the right track. Planning on getting the bumper off next weekend, so can swap parts such as ballast across to try and rule things out, and will have a new bulb in a day or so, so can test this, however as I'm getting close to zero current coming from the wiring loom that goes into the black box then it must be a new ballast I need right?
Any help appreciated, as always!
