No idea personally but welcometomyturbodies. Is the fuse blown or something or are you having some other problem?:)

Is it under a clear plastic cover? If so, it's the coolant glow plug fuse. It commonly burns out. It powers the 3 GP on the coolant flange. Helps warm up the engine but since not in engine, does not make any difference in engine starting. Clean the contacts and make sure they're good if you choose to replace.
