THIS BULLETIN APPLIES TO VEHICLES BUILT BEFORE JULY 20, 1998 (MDH 0720XX). THE LAST SIX DIGITS OF THE V.I.N. WILL BE IN THE ONE HUNDRED THOUSAND SERIES (1XXXXX).
SYMPTOM/CONDITION:
The following conditions may exist:
ATC Temperature Drift:
On long trips of 60 minutes or more in cold ambient temperatures (00 to 30° F, -1 to 18° C) the A/C system drifts to a cooler setting in the "AUTO" mode. This may be accompanied by temperatures too cool in the upper body area or too hot in the foot area.
ATC Snowflake Symbol:
The ATC snowflake symbol turns on in the ATC control display during cool weather (as low as 45° F, 7° C) in the "AUTO" mode.
Manual A/C Temperature
Control Settings:
Air from the climate control system is too cool in cold weather when the temperature control is set between the 1/2 to almost full heat setting (highest temperature). This may occur when the operator lowers the temperature setting after initially heating the vehicle.
