Re: Low Speed Fan Relay at idle
PDC is indeed Power Distribution Center and its the relay and fuse box under the hood, next to the battery. Newer WJ´s have 2 relays for the cooling fan, the high speed and low speed relay´s and they are in this box. Older WJ´s where using a pulse width modulated relay, which was hidden under the right hand side headlight (viewed from drivers position).
