HEATER/AIR CONDITIONER APPEARS TO OPERATE ON ONLY THREE SPEEDS
Model and Year:
1992 M/L VANS
Some 1992 M/L van owners may comment that the fan lever on the heater control panel does not allow for a comfortable range of air flow settings. The
selector lever was designed to allow for five comfort positions. Starting from the off position, the airflow is increased through four speeds by moving the
lever to the right toward "HIGH".
Currently, the first two positions have only a slightly noticeable difference in air flow. When the lever is moved to the third position, the air flow
increases dramatically.
If your diagnosis of the blower system (see the flow chart in section 1A-13 of the M/I Service Manual) indicates a malfunctioning blower speed switch,
DO NOT replace the switch. The correction of this condition requires the redesign of the resistor. The redesigned resistor will not be available until
approximately April 1992. When the correction is implemented, you will be informed via a Dealer Service Bulletin.
