So I had this problem roughly 3 months ago where my passenger headlight and AC went out simultaneously. I stopped using the AC for about a week and changed my bulbs for my headlights out, everything worked. Fast forward to 3 days after installing these new bulbs, I'm driving and yet again my bulb goes out along with my AC.

Please help, this is rowing very annoying. Any and all information is greatly appreciated.

Thanks!

Check the wiring in that area for chafing or shorting.
