Multimeter and check connections at the back of the lights...?

I had the same problem. I replaced the combination switch and it worked

i am having a similar problem with one of my head lights. the passenger side is fine but my drivers side headlight won't work i am getting 10volts on all 3 terminals on the plug.

any ideas?

For there to be 10V an all three terminals it would have to be something like a bad earth connection on that side?

Ive had a similar problem before. i added another earth strap on the left side of the engine to the chassis and that seemed to fix the problem
