Test E: A Single Power Window Is Inoperative - LH Or RH Rear
PINPOINT TEST E: A SINGLE POWER WINDOW IS INOPERATIVE - LH OR RH REARNormal Operation
Under normal operation, the rear window control switches receive power from the LH front window control switch through circuit CPW14 (VT/WH) when the lock out feature is not active.
Rear Window Operation From the LH Front Window Control Switch
When the LH rear window is operated up from the LH front window control switch, power is sent to the LH rear window control switch through circuit CPW15 (YE) and ground through circuit CPW16 (BU/OG). The LH rear window control switch transfers power to the LH rear window motor through circuit CPW21 (BN) and ground through circuit CPW22 (GN/VT). When the RH rear window is operated down from the LH front window control switch, power is sent to the RH rear window control switch through circuit CPW17 (BN/GN) and ground through circuit CPW18 (GY/VT). The RH rear window control switch transfers power to the RH rear window motor through circuit CPW23 (GY) and ground through circuit CPW24 (WH/VT).
When the LH rear window is operated up from the LH front window control switch, power is sent to the LH rear window control switch through circuit CPW16 (BU/OG) and ground through CPW15 (YE). The LH rear window control switch transfers power to the LH rear window motor through circuit CPW22 (GN/VT) and ground through circuit CPW21 (BN). When the RH rear window is operated up from the LH front window control switch, power is sent to the RH rear window control switch through circuit CPW18 (GY/VT) and ground through circuit CPW17 (BN/GN). The RH rear window control switch transfers power to the RH rear window motor through circuit CPW24 (WH/VT) and ground through circuit CPW23 (GY).
Rear Window Operation From the LH or RH Rear Window Control Switch
When the LH rear window is operated down from the LH rear window control switch, power is sent to the LH rear window motor through circuit CPW21 (BN) and ground through circuit CPW22 (GN/VT). When the RH rear window is operated down from the RH rear window control switch, power is sent to the RH rear window motor through circuit through circuit CPW23 (GY) and ground through circuit CPW24 (WH/VT).
When the LH rear window is operated up from the LH rear window control switch, power is sent to the LH rear window motor through circuit CPW22 (GN/VT) and ground through CPW21 (BN). When the RH rear window is operated up from the RH rear window control switch, power is sent to the RH rear window motor through circuit CPW24 (WH/VT) and ground through circuit CPW23 (GY).
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- LH front window control switch
- Rear door window motor
- LH or RH rear window control switch
