Heater - Low Performance
NO: 24-04-97
GROUP: Heating & A/C
DATE: Apr. 4, 1997
SUBJECT:
Poor Heater Performance On Passenger Side
MODELS:
1997 (AN) Dakota
SYMPTOM/CONDITION:
Low heater performance due to improperly directed heater air flow.
DIAGNOSIS:
Inspect the passenger side floor duct outlet to verify the direction of airflow from the outlet. If the airflow direction from the duct is perpendicular
(straight down) to the heater housing, perform the Repair Procedure. If the floor duct is directing the airflow toward the passenger's legs, further
diagnosis of the heater/A/C system is required. Refer to the 1997 Service Manual (Publication No. 81-370-7110), pages 24-10 through 24-15 for
information regarding heater performance.
