High beams don't work even though fuses, relays, and bulbs are fine
When high beams fail to turn on and the dashboard indicator lights up despite functional bulbs, fuses, and relays, the underlying issue usually lies further up the circuit in the multifunction switch or wiring. This leaves drivers stuck without high beams while online searches keep bringing up results for low beams instead.

“I recently acquired a 07 Yukon, and the high beams do not come on. I've checked the fuses, checked the relays, and checked the bulbs to see if the filaments were broken and everything's checked out fine.”source ↗
“And trying to search on online just leads me to forums only talking about low beams being out or fuses. What am I missing here.”source ↗
“When I switch to my high beams it does not make any difference other than the indicator on my dashboard telling me they are “on”.”source ↗
