Check it out and no disrespect Dan...You just can't just wave a magic wand over an issue like that...You a have body processor that controls the lights, all the wiring, the connectors, and the bulb sockets...It makes that warning based on voltage drop so any connections not good can cause that...You have connectors buried under trim panels and carpet and all kinds of shit to inspect and clean to start with and that just takes time and money...I get your point, but most shops don't want to deal with stuff like that in the least...I know I don't..Money wise that is a loser...J
