t/a99

I have a 99 T/A and when the lights are on all 4 lights are on but the high beam switches not on. Also all are dim but the right side low beam that is bright like it should be. If i put on the high beam switch the left side lights go out but the right side both on as they should be. I have all new headlights high and low beams installed. What should i look at to fix this issue?.. Thanks

Ground issue in the harness

Like the other member mentioned, it's a ground issue. We had similar on our 2000 and it was actually the visible ground on top of the core support on the driver side... It appeared tight and looked good but was actually the problem.

I'm having the same issue. I looked at the visible ground and checked the harness. I didn't see any issues. Did you manage to solve your issue? If so, how?

Did you remove and reinstall the ground connection? Its pretty common to find ugly stuff under the bolt that you cant see unless you take it out.

Almost a year late, but I found my issue was with the 5-pin wiring harness. I cut the connector head and installed a new one, that fixed the issue.
