headlight and foglight issue

Post by van883 »

When my headlights are on, one foglight glows dimly..But when I turn the foglights on, both of them shine brightly!

What is going on? The car is new to me.

thanks

Ah ha! There are two major earths on the 944 just inside of the headlights when you lift the bonnet that would be a good first shot. Also check all the bulbs are kosher, I've seen a blown bulb do really weird things.
