INSPECT DEF. MODE SWITCH CONTINUITY
Check the continuity exists between terminals while switch is pressed.
If no continuity exists, replace the heater switch.
3. w/ A/C and two way flow heater models:
INSPECT HEATER SWITCH CONTINUITY
Check the continuity exists between terminal 1 and 2 while switch is pressed.
