The low beams cut out intermittently. I tried a new #46 relay and it still is doing the same thing. On and off with no rhyme or reason. Also, this vehicle also has a battery drain problem. The battery was draining overnight. I used a meter to determine that a draw was coming from the radio. I pulled that fuse and the battery no longer drains. Could there be any relation? First priority is the lights.

As far as the lights, are they affected by bumps or anything specific you can think of? Have you done any other work so far? For example, has the switch been replaced, have you confirmed the fuses are in good condition, not corroded in the box, and making a good connection? Do both low beams turn off?

Let me know. If I had to guess, I feel it is likely a poor connection at the fuse box (fuse), but let's do some diagnostics first.

Let me know.
