Hey All, So interesting HL issue Im having and hoping for some help. On my '72 camaro, HL didnt work but parking lights, tail, brake lights, etc worked. After a quick look, I discovered the dimmer switch was completely broken in 2 pieces. I swapped for a new dimmer switch and the HL issue was solved....so I thought. My first drive a night, I realized that only highbeams worked and nothing for the low. When idling for about a minute, the HLs start flickering off and on. If I turn the HLs off by the switch, and turn the HLs back on they stay lit and solid for about 30 seconds before beginning the flicking issue again. Ive rechecked the connections at both the dimmer and the HL switch and all appears to be good. Not sure what's causing my issue. Any ideas?
