Condition:
At high ambient temperatures of 105~F (41~C) and above, the radiator cooling fan stays on high speed with the ignition off, discharging the battery.
At these ambient temperatures, gas pressure of the R12 refrigerant activates the A/C high pressure switch and triggers the high speed radiator fan relay.
Service Solution:
(Refer to applicable wiring diagram)
Replace the radiator fan high speed relay with Part No. 321 919 505A and modify the A/C high pressure switch wiring as follows:
