A few weeks ago, one of the high beams would sometimes work, and sometimes not work. Then it just stopped working all together. Now the Daytime Running Lights are sometimes working, sometimes not working. Currently not working at all.. The same bulb houses both the DRL and the High Beams.

Right now, all I have is one high beam working out of one bulb. Is it the bulbs that are gone on it or a bigger issue?

Im guessing it is either the bulb, or the ground. Pull em out and check, easiest way to diagnose

I just pulled the bulbs out and they both are still good.. So the issue is in the wiring somewheres. Where do I start?

id check the ground on that side, its on the frame rail. Then the plug itself, and the DRL module.

Get a multimeter and do a continuity test on the bulb, and swap it ot the other side of the car just to make sure its bad

Now all the lights just started working, but the A/C stopped working and the fan would cut in and out.. Is there some kind of module that would control this?

that really sounds like a ground issue to me.
