A/C Evaporator Freeze Up - 1997-1999 Jeep Cherokee & Wrangler

NO: 24-13-99

SUBJECT: A/C Evaporator Freeze Up

DATE: July 2, 1999



This bulletin involves installing a revised low pressure cycling switch.



Intermittent low A/C output due to reduced airflow through the evaporator or excessive condensation draining from the vehicle after the vehicle has been turned off due to evaporator freeze up. The system will operate normally in most conditions. The condition will only occur after extended periods of driving with the A/C system operating. The system will return to normal operation after the A/C system has been turned off long enough for the ice on the evaporator to melt.
