1. Sight and sound checks

   Check relay operation, blower motor rotation, light illumination, etc. Listen for a "click" when some relay covers are pushed down.

2. Simple checks

   For example, if a headlight does not come on and a faulty fuse or poor grounding is suspected, replace the fuse with a new one. Or use a jumper wire to ground the light to the body. Determine which part(s) is/are responsible for the problem.
