Checked fuse on the compartment under hood as well as relay in the compartment. Both ok. Foglight indicator comes on dash when switch is on. Tested bulbs direct 12 v to bulb terminals bulb lit up. They are Hella non led yellow bulbs been working fine over a year now. Any ideas?

I don’t know of any specific 200 fog light issues, but I can offer some basic troubleshooting. I’d start by looking for 12v in the fog light plug.when they should be on. Use only the connector to check. If you don’t have that, I’m assuming you won’t since the light bulbs have been checked, I’d check for continuity between relay and the plug and from ground to the plug. Maybe you disconnected a body ground, or I guess possibly it needs to be cleaned up. If you have continuity everywhere, I’d recheck the relay. And check that it’s getting 12v when it should.
