where to go for electrical repairs?

[boomshakalaka]

My passenger tail has always had a slight flicker and thrown a code, but now the entire thing is not working at all. I dont want to get a ticket so I want to get it fixed asap. Who do I go to to get it fixed? I would try and do it myself but I hate electrical stuff. Should I look for an automotive electrician specialist, or just stick to a bmw specialist?

p.s. my drivers window goes off track when not fully closed it seems. When I go over a bump or close the door I can hear the window pane hitting against something. Its annoying and Im afraid Ill shatter the glass eventually. I plan to take it up to this auto glass place down the street but was curious if anyone knew if this was a common issue and how much it costs to repair it.

DO you have the celis tails? If so, your ballast is either not connected fully or its gone bad. Try to mess around with it by disconnecting and reconnecting. Im thinking its a bad connection. If all else fails, start looking for a new one.

man this is probably a dumb question, but how do I know if I have celis (they arent stock obviously but they were on the car when I bought it) and what does the ballast look like?
