Thank you for replying. We’ve switched the ballast, bulb, and even the whole headlight to the other side but the problem remains in the passenger side. We checked the relay connection in the fuse box with a circuit tester, 2 of the power pins & 1 ground pin sends steady connection, but when testing 1 ground pin, the tester flickers on and of as if there wasn’t a steady circuit/signal. What would have to be done next? Should it be an easy fix or should I just take it to the dealer?
