Test 17C - Inoperative Mode Door

WARNING: This page is about a different car, the 1994 Eagle Vision, 1994 Dodge Intrepid, 1994 Chrysler New Yorker, 1994 Chrysler LHS, and 1994 Chrysler Concorde. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Perform TEST 17A before proceeding with this test.

Using DRB, calibrate ATC doors. Using external DVOM, backprobe Dark Green/Yellow wire at 10-pin HVAC connector, located near plenum. If voltage is not higher than 10 volts all the time, go to next step. If voltage remains above 10 volts, repair short to voltage on Dark Green/Yellow wire, and replace BCM. Perform VERIFICATION TEST.
Observe voltmeter while pressing panel, defrost, and bi-level switches, one at a time, on ATC panel. If voltage remains less than 10 volts as any switch is pressed, go to next step. If voltage increases to above 10 volts as each switch is pressed, inspect mode door for free movement. If mode door is okay, replace mode door actuator. Perform VERIFICATION TEST.
Using external DVOM, backprobe Black BCM connector cavity No. 16 (Dark Green/Yellow wire). BCM is located above right kick panel. Observe voltmeter while pressing panel, defrost, and bi-level switches, one at a time, on ATC head. If voltage remains less than 10 volts as any switch is pressed, go to next step. If voltage increases to above 10 volts as each switch is pressed, repair open Dark Green/Yellow wire between 10-pin connector and Black BCM connector. Perform VERIFICATION TEST.
Turn ignition off. Unplug Black BCM connector. Unplug 10-pin HVAC connector. With DRB in ohmmeter mode, probe Black BCM connector cavity No. 16 (Dark Green/Yellow wire). If resistance is less than 5 ohms, repair short to ground on Dark Green/Yellow wire, replace BCM and perform VERIFICATION TEST. If resistance is not less than 5 ohms, replace BCM and perform VERIFICATION TEST.
