Pinpoint Test B
- Locate the moon roof switch. Measure the resistance of the Black wire at the moon roof switch and ground. Is the resistance less than 5 ohms? If yes, go to next step. If no, repair the ground circuit (Black Wire).
- Disconnect the moon roof switch connectors. Verify switch position resistances. See SWITCH POSITION RESISTANCE .
SWITCH POSITION RESISTANCE
| Switch Position | Resistance Between "BK" Wire And: | Resistance |
|---|---|---|
| Open | BL | < 5 Ohms |
| Close | BL/W | < 5 Ohms |
| Up | BL/Y | < 5 Ohms |
| Down | BL/GN | < 5 Ohms |
Is the moon roof switch operating correctly? If yes, go to PINPOINT TEST C . If no, repair or replace the moon roof switch. See MOON ROOF SWITCHES under REMOVAL & INSTALLATION.
