Inspection 1. Measure the pressure of high pressure line by measuring voltage output between NO.1 and NO.2 terminals. 2. Inspect the voltage value whether it is sufficient to be regular value or not. Voltage = 0.00878835 * Pressure + 0.37081095 [PSIA] 3.
Replacement 1. Disconnect the negative (-) battery terminal. 2. Remove the heater and blower unit.(Refer to HA group – heater unit). 3. Remove the blower unit (A) from the heater unit after loosening a mounting bolt and 3 screws. Make sure that there is no air leaking out of the blower and duct joints.
