Last week, I heard relay clicking and the dash lights went on and off, then back on and stayed on. Now the dash lights don't turn on and neither do the fog lights. I've checked all the associated fuses plus more to make sure. I took out the relays (1 & 4), took off their covers and they all looked visually fine and didn't smell like electrical burning or anything. Any other suggestions? Or, what is the correct way to see if a relay works?
