It's me again! I noticed tonight my rear fog light does not turn on. Yes I do know it is only on the driver's side on the upper right hand position of the tail lamp. The bulb is good, and the light in the switch turns on, but according to my multimeter, no power is making it to that portion of the circuit board. The fuse is intact.

My big question is this: Does the light coming on in the switch necessarily mean the switch itself is working? Since the rest of the wiring to the rear lights is intact, I doubt the one wire to the fog lamp would be bad somewhere along the way, so I am thinking it might be a switch issue. Thanks for the help!

 

probably help if you told us what year and model this was.... 240/740/940 covers 20 years of 3 models.

light on in the switch suggests the switch is getting power.

 

Absentminded me. Yeah that would help! It's a 1988 244DL.

 

its a white wire, goes directly from the switch, through a 3x3 block connector thats near/behind the fuse panel, then along the driver side floor sill back to the left tail light.

 

Thanks! I'll chase the wire this weekend.

 

On second thought, someone backed into my tail light and a replacement is on the way! I'll see if the replacement works. Maybe it was an issue with the printed circuit board. I'm crossing my fingers that I don't have to chase the wire!
