If REAR WIPER and INTERMITTENT button LEDs are flashing simultaneously, perform calibration test.
If REAR WIPER and INTERMITTENT button LEDs are flashing alternately, level one codes are present. REAR WIPER button LED indicates level. INTERMITTENT button LED indicates value. Each time REAR WASH button is pressed, display will cycle to next level. After level 5 is reached, it will cycle back to level 1.
LEVEL CODE VALUES
2Mode Potentiometer Test
3Blend/Pass. Potentiometer Test
One flash indicates fail codes. A 2-flash sequence indicates mode potentiometer test. A 3-flash sequence indicates blend/passenger side potentiometer test. A 4-flash sequence indicates evaporator probe temperature.. A 5-flash sequence indicates driver side potentiometer test. INTERMITTENT button LED indicates failure code (level 1) or potentiometer position (level 2, 3 or 5). See LEVEL 1 - FAILURE CODE VALUES table.
Temperature and mode potentiometers can be tested after calibration is complete by pressing REAR WASH button and cycling to level 2, 3 or 5 as displayed by REAR WIPER button LED. Press REAR WASH button once, REAR WIPER button LED will begin a 2-flash sequence (level 2). Move mode selector switch from PANEL to DEFROST and INTERMITTENT button LED flash rate should decrease. Move mode selector switch from DEFROST to PANEL and INTERMITTENT button LED flash rate should increase.
Press REAR WASH button again, REAR WIPER button LED will begin a 3-flash sequence (level 3) or depress REAR WASH twice for level 5. At either level, move temperature selector lever from COLD to HOT and INTERMITTENT button LED flash rate should increase. Move temperature selector lever from HOT to COLD and INTERMITTENT button LED flash rate should decrease.
