I'm trying to get the fog/driving lights on my 1990 Accord LX to work. Popped the dash switch out and took it to Autozone for testing; it was good. There is no power to the switch. I couldn't find a fuse that was bad. What would kill power to the switch?

 

Are you sure the ground isn't bad? When you tested for power, where did the put the negative lead of the voltmeter? Black wire or grounded to chassis?

 

I just used a two prong, red/black pocket sized circuit tester, not a voltmeter (first mistake?). I poked the two leads every which way to every combination of the plug holes, and no light, so I assumed there was no power to the switch (second mistake?). Electrical work is not my forte, obviously....

 

Don't worry, electrical is not my forte either. The black (-) wire coming from the connector, follow it. It should bolt down to the metal dash frame along with a ton of other ground wires (like 10 or so at each bolt).

Alternatively, put the red (+) prong on the positive wire going into the switch and then put the black (-) on a part of the dash frame or find a set of grounds.
