A/C Signal: Testing and Inspection
Fig. 3 A/C Switch Test:
1.
Remove A/C Switch, and check continuity according to
Fig. 3. 2.
If continuity is not as specified, replace switch.
The A/C switch signal can be checked at ECU terminal 1Q. With blower motor and
ignition switches "ON," terminal voltage should read below 2.5V with A/C switch "ON" and approximately 12V with A/C switch "OFF."
