I seem to be having some difficulty with my fog lights. I noticed the other day that both of my fog lights on my 85 iroc where out. I tried flipping the switch because I figured maybe it was off. But, no it didnt help anything. My question is how can I troubleshoot my fog lights to get them to work again?? I dont think its a burned out bulb because both of them are out. Thanks guys!

 

Check the fog lamp relay on the left fender well in the engine compartment. Located roughly under the left hood strut.

 

I went to check this the other day and I wasnt sure how to check this. Do i use one of those test lights?
