Chrysler Crossfire. Manual — part 375
*WASHERS INOPERATIVE (CONTINUED)
3.
MEASURE RESISTANCE ACROSS MULTI-FUNCTION SWITCH
Note: If any BCM DTCs are set, diagnose them first before con-
tinuing.
Turn the ignition off.
Disconnect the Multi-Function Switch harness connector.
Note: Check connectors - Clean/repair as necessary.
Depress the washer switch, and measure the resistance between cav-
ity 8 and cavity 11 of the Multi-Function Switch.
Is the resistance below 5.0 ohms?
Yes
>> Repair the Washer Pump Motor Control circuit for an
open.
Perform BODY VERIFICATION TEST.
No
>> Replace the Multi-Function Switch. (Refer to 8 - ELECTRI-
CAL/LAMPS/LIGHTING - EXTERIOR/MULTI-FUNCTION
SWITCH - REMOVAL)
Perform BODY VERIFICATION TEST.

Diagnostic Test
1.
MEASURE MULTI-FUNCTION SWITCH RESISTANCE
Note: If any BCM DTCs are set, diagnose them first before con-
tinuing.
Disconnect the BCM harness connector.
Note: Check connectors - Clean/repair as necessary.
Disconnect the Multi-Function Switch harness connector.
Note: Check connectors - Clean/repair as necessary.
Turn the ignition on.
Measure the voltage of the Washer Pump Motor Control circuit at cav-
ity 8 of the Multi-Function Switch harness connector.
Is voltage present?
Yes
>> Repair the Washer Pump Motor Control circuit for an
open.
Perform BODY VERIFICATION TEST.
No

MEASURE MULTI-FUNCTION SWITCH RESISTANCE
Note: If any BCM DTCs are set, diagnose them first before con-
tinuing.
Turn the ignition off.
Disconnect the Multi-Function Switch harness connector.
Note: Check connectors - Clean/repair as necessary.
Measure the resistance of the Multi-Function Switch between cavity 8
and cavity 11.
While measuring the resistance, depress the washer switch once and
release.
Did the resistance reading go from infinite to less than 5 ohms
to infinite?
Yes
>> Replace the Body Control Module. (Refer to 8 - ELECTRI-
CAL/ELECTRONIC CONTROL MODULES/BODY CON-
TROL/CENTRAL TIMER MODUL - REMOVAL)
Perform BODY VERIFICATION TEST.
No
>> Replace the Multi-Function Switch. (Refer to 8 - ELECTRI-
CAL/LAMPS/LIGHTING - EXTERIOR/MULTI-FUNCTION
SWITCH - REMOVAL)
Perform BODY VERIFICATION TEST.
