Blower Switch Test
Remove the connector from the Blower Resistors. Measure the voltage to ground at the Blower Switch connector on the A/C Control Assembly, with the
connector still connected.
^
If any of the voltages above are not correct, install a new Blower Switch.
Test D: Blower Resistor Test
Blower Resistors Test
Backprobe the connector to the Blower Resistors with the connector still on the resistors, and measure the resistance between the wires listed in the chart.
The resistance values are approximate.
^
If resistors are open, shorted, or different from the values given, install new Blower Resistors.
Test E: Blower Relay Test
