I need all your help on this one as I am completly out of ideas and troubleshooting this ongoing problem. Basically 3 months ago my driver side H.I.D failed upon start up I thought no big deal must because its getting colder outside so I turn the light switch off and on and still the driver side will not light up....So I open the hood and check connections everything ok then drive over to shop were I had them installed because I wanted a warranty if anything went wrong in a case like this that they would fix it and I would not have to buy new parts like ballast or bulbs if it were to fail. Anyway, the shop said it was a bad ballast and replaced it and got it working again for 2 days then the driver side went out again so I drive back to the shop as soon as it happened and they turned the light off and on and then the light magically turns on...So I drove home then got in my car to check 2 hours later in the driveway and once again upon startup driver side does not turn on so I flicked the switch about 10 times and nothing. So I opened the hood again checked connections and by that time the shop was closed so the next day after work I went back to the shop and told them the light keeps going out and they said they replaced the bad ballast and decided to put on another ballast and it worked. Everything went fine for a week then I turn the car on and the driver side H.I.D. is out again! So I decided to just leave it sit for the weekend and when I turned it on 2 days later it magically starts working again...another couple days goes by and the lights are out again so I flick the switch on and off and nothing so after work I go back to the shop and they said they cannot figure it out so I suggested using a relay so they put one on along with another new ballast (3rd ballast by the way) and that worked for 2.5 hours then I get into the car to start it up that same night with new ballast and relay and still Fail driver side out!!!! At this point I call the owner of the shop and he is out of ideas and says must be a problem with the cars harness and or recharching system. The owner took me into the shop and showed me in person that the ballast was getting the correct voltage and the ground was connected to stock ground. At this point I am livid and demand a whole new set 2 new ballast 2 new bulbs new wiring because (I'm really thinking this is cheap ass H.I.D. kit) so new kit goes on a month goes by no problems then AGAIN the driver side H.I.D. fails to light!!!!!!! If anyone can help because I had many H.I.D. kits in the past and never had this many problems put in myself or shop and only with this car am I coming across these problems and I'm sick of it.
