2. Control switches (raising the sunroof and closing the damper) close the ground circuit of the sunroof drive motor. Power begins to flow to the electric motor through the relay. Turn on the ignition (but don't start the engine) and check the opening of the sunroof and the operation of the damper.
3. Listen carefully for the noise of the motor when it is turned on.
4. If you hear motor noise but the sunroof remains stationary, the problem may be with the sunroof movement mechanism or control cables.
5. If the sunroof is stationary and no motor noise is heard, check the fuse first (on the Probe, this is fuse #5. has a rating of 15 A and is installed in the fuse box located in the passenger compartment. In a Mazda model, check the sunroof fuse).
6. If the fuse is good, remove the control switches located on the overhead console. Disconnect the wiring from them. Turn on the ignition and check the voltage at the switch terminals. There should be voltage across four terminals. If there is no voltage, check the supply voltage and grounding of the drive. If drive power and ground are good, but not at the switch terminals, replace drive. If there is no power to the drive, check the ignition relay as well as the wiring between the ignition relay and the drive.
7. If the supply voltage is present at the switch, disconnect it. Check for contact between the switch terminals in all positions (pic. 27.7).
8. If the switch is OK, connect it. Locate the ground wire of the switch and connect with a jumper switch and connect the switch to vehicle ground with a jumper. If the sunroof motor starts running, repair the ground wire.
9. The sunroof can be closed manually. To do this, turn the motor shaft clockwise with a socket wrench.
