I replaced the switch, the relay and the bulbs and my high beams do not work.

Hi,

When you checked or replaced the relay, did you confirm there is power to it as well as a ground signal when the high beam lights are requested?

Do me a favor. Take a look at this link. It explains how to test a relay and how to check for power to the relay. Check what is indicated and let me know the results.

I will watch for your response.

Take care,

Joe
