So my driver side headlight would sporadically stop working, until it finally shiat the bed. every now and then it comes back. I swapped bulbs, it wasn't the bulbs. In the combination switch fog lights, turn signal and high beams all work properly. My guess is its a loose connection somewhere between the combination switch and the socket where the bulb attaches. Is there any way to confirm this before I go and order a new switch? I've already taken it apart and doused it in elecrtical parts cleaner, to no avail. Every time I try looking at the electrical diagrams in the service manual I get a headache. I'm not kidding. so, has this happened to anyone else? is there a simple way to identify the fault. Thank you in advance.
