David, First, did you check the bulb with 12 volts directly applied to the bulb connectors, or did you use an ohmeter to check resistance. Ohmeter may give a false reading so always check with 12 volts applied. Second, the engine bay light does not go thru a relay, so I do not know why a relay is clicking. Power from the light comes directly from the battery via the #12 fuse, then thru the switch attached to the firewall (left side) that is opened and closed by the tab attached to the engine cover, then to the light bulb. When you open the cover, the switch closes and applies power to the bulb. Can you determine which relay is clicking when you remove the bulb? If so, then you need to check the wiring diagram from that relay and determine why the engine bay light is applying 12 volts to it. My thoughts are you have some wires misrouted somewhere.

Bulb checks OK. Relay on firewall clicks on and off as bulb is being removed and replaced. Any ideas??
