One Headlamp on

Rich in Vancouver · 7th August 2022, 16:04

Here's an odd electrical issue.
Yesterday I parked my ZT-T in the driveway, locked it with the remote and came inside. A while later my wife commented that my headlights were on.
When I went out and took a look I found that only the L/H Zenon was lit.
I unlocked the car with the remote and the light went off. Relocked it and the light stayed off.
Has anyone run into this issue before? Bad ground? Canbus issue? Witchcraft?
The car had been out in the rain for the first time in a year.

Any tips appreciated!

Was the tail lamp illuminated on the opposite side?

Ooh, I'm not sure. If it happens again I'll check.
What would that indicate?
I had the car out today and the problem didn't repeat itself.

If it happens again and the tail lamp is illuminated on the opposite side it's down to a bad connection in connectors underneath the under bonnet fusebox. Usually unplugging them and reconnecting gets rid of the issue.

The reason for your problem is most likely caused by damp

Thanks Russ!

I'll put the fusebox plug on my list of things to do.
