What's up? Since I've first got my car(about a year ago) the vent sliders and blower fan switch lights never worked. Oh, I've got the fiber optic ones. Yeah, so the lights NEVER worked during the night, and all of a sudden they worked randomly tonight! What's with that? I do, however, remember them blinking once, and forever remaining off--that happened about a month ago. Any ideas on what is with these random lights? TIA everyone.
