random foglamps

[tommyturbo]

my foglamps every once in a while on the 89 will not work, but 99% of the time they work fine. Any ideas? I doubt it's a fuse, the mystery fuse I read about. So maybe a relay? Where is the foglamp relay on this?

 

[Mazdarx]

It's probably something like a ground for the lights, have you checked that stuff?

 

[tommyturbo]

I don't know where the grounds are, I don't have any kind of service books, or wiring diagrams. They have been working perfectly lately. Only seem to act up if i turn the foglight switch on or off, but if I just leave the switch on, they seem to always work.

that would tell me to check the switch

I had this exact problem on my 91. I replaced the switch and have not had a problem since.

89's don't have a relay, the switch is most likely the culprit. These switches, being one year only (89's were the first SHO's, later years got a different dash) are hard to find as well.

Yes. Check the switch because mine does the same thing and all I do is tap on the switch and it comes back on. So all thats telling me is to change the switch...and I have an '89 by the way.

On my old Gen 1.. the thing that was always the problem for me was the little screw that holds the bulb in. If I kicked the bumper or wiggled the wire it would pop on.


If its both lights at the same time, I would think more so the switch or the ground in the harness there.. if its only one look in the fixture.

Yes check the little pin that holds the bulb in place on the foglight housing, it grounds it and sometimes is a bit loose.
