Mode Door Feedback Circuit

CAUTION: Do not use a meter with an impedance of less than 10 Meg ohms.

Insert the positive voltmeter probe into terminal D (circuit 362) and the negative probe into terminal 11 (circuit 361). Test the voltages in all three positions and compare them to the values below.

Mode Door Position Correct Feedback
Voltage (+/- 0.08V)
Full Vent (A/C) 0.20V
Full Lower (Heater) 2.50V
Full Defrost 4.77V
