It most likely is in the switch. Take a light tester and check your wires. Find out which wire sends the signal to the high beems, trace it back to the wiring from the light switch and see if it's outputting when you pull back. If not, problem is for sure in the switches and you could just snag some from a junk yard. This is a good time to upgrade to intermittent wipers if you don't already have them, but remember to get the intermittent relay too so it'll work
