# ROUGH/LOW IDLE OR W/S FOGGING A/C FAN RELAY

"Please discard previous hulletin 83-T-30A Section 1 issued 7183 due to change in part numbers and diagram. "

Low engine idle can be caused by high A/C compressor loads due to high head pressures resulting from compressor operation without engine cooling fan operation while in defrost mode.

This condition can be corrected by installing an additional engine cooling fan relay, Part Number 14078902 for 6000 and Phoenix models or 14073422 for 2000 models, (see diagram below) to operate the engine cooling fan in defrost mode.

A connector body, Part Number 12010015 and terminal ends, Part Number 8905087 are available through WDDGM for simplification of the installation of the additional cooling fan relay. The relay should be installed on the cowl, adjacent to the pressure cycling switch. Any wiring run through the cowl should be routed through exisiting grommets and care be taken to maintain cowl sealing.
