INSPECTION
PROCEDURE
1. INSPECT AIR CONDITIONING CONTROL ASSEMBLY
(a) Check the blower switch resistance. (1) Measure the resistance according to the value(s) in the table below. Text in Illustration
Standard Resistance:
If the result is not as specified, replace the air conditioning control assembly. |
|
(b) Check the operation. (1) Apply battery voltage across terminals 14 (IG+) and 1 (GND). (2) Connect the positive (+) tester probe of a voltmeter to terminal 2 (AMSW) and negative (-) tester probe to terminal 1 (GND), then check the voltage. Text in Illustration
Standard Voltage:
If the result is not as specified, replace the air conditioning control assembly. |
|
(c) Check the operation. (1) Apply battery voltage across terminals 14 (IG+) and 1 (GND). (2) Connect the positive (+) tester probe of a voltmeter to terminal 3 (MSET) and negative (-) tester probe to terminal 1 (GND), then check the voltage. Text in Illustration
Standard Voltage:
If the result is not as specified, replace the air conditioning control assembly. |

(d) Inspect the illumination.
(1) Connect the positive (+) lead to terminal 6 (ILL+) and negative (-) lead to terminal 9 (ILL-), and check that the illuminations comes on.
OK:
Illuminations comes on.
If the result is not as specified, replace the air conditioning control assembly.
