POWER WINDOW MOTOR

Remove window motor from vehicle, see POWER WINDOW MOTOR R & I under REMOVAL & INSTALLATION. Using fused jumper wires, connect a fully charged battery to motor terminals. Observe motor. Motor should operate smoothly. Reverse leads. Motor should operate in reverse direction. Replace window motor if it does not operate as specified.

ACCESSORY DELAY RELAY

Remove accessory delay relay from relay module located behind center of instrument panel. Check continuity using an ohmmeter. Continuity should exist between relay terminals No. 85 and 86, and also between terminal No. 30 and terminal 87A. (Scheme 10) Using fused jumper wires, connect battery terminals to relay terminals No. 85 and 86. Continuity should now exist between relay terminals No. 30 and 87. Replace relay if continuity is not as specified.

BATTERY SAVER & ONE-TOUCH DOWN RELAY

Remove battery saver relay or one-touch down relay from relay module located behind center of instrument panel. Check continuity using an ohmmeter. Continuity should exist between relay terminals No. 1 and 2, and also between terminals No. 3 and 4. (Scheme 11) Using fused jumper wires, connect battery terminals to relay terminals No. 1 and 2. Continuity should now exist between relay terminals No. 3 and 5. Replace relay if continuity is not as specified.

PRELIMINARY PROCEDURE

Verify customers complaint by operating power windows. Check window alignment, window mounting, window frame interference or damaged switches. Check for blown fuse(s), loose or corroded connectors, or damaged wiring harness. Repair or replace components as necessary.
If all components are okay, connect NGS tester to DLC located below instrument panel. Using NGS tester, perform DATA LINK DIAGNOSTIC TEST. If NGS tester displays CKT 914 or CKT 915=ALL MODULES NO RESP/NOT EQUIP, see MODULE COMMUNICATIONS NETWORK article to diagnosis network concern. If NGS tester displays NO RESP/NOT EQUIP for Generic Electronic Module (GEM), perform «TEST J: NO COMMUNICATION WITH GEM»(ref-29364-S10965897562001010800000) under SYSTEM TESTS.
If NGS tester displays SYSTEM PASSED, retrieve and record continuous DTCs. Erase continuous DTCs. Perform self-test diagnostics for GEM/CTM using NGS tester. If GEM/CTM DTCs are retrieved, see GENERIC ELECTRONIC MODULE/CENTRAL TIMER MODULE (GEM/CTM) DTC DEFINITIONS table to continue diagnosis. If no DTCs are retrieved, perform appropriate test under «SYSTEM TESTING»(ref-29364-S36994198232001010800000) .
