2. Control switches (lifting the hatch and closing the damper) close the grounding circuit of the hatch drive electric 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 hatch and the operation of the damper.
3. Listen carefully to the noise of the electric motor when it is turned on.
4. If you hear the motor making noise, but the sunroof remains stationary, the problem may be with the sunroof mechanism or control cables.
5. If the sunroof is stationary and there is no motor noise, first check that the fuse is working properly (in the Probe model, this is fuse No. 5. It has a rating of 15 A and is installed in the fuse box located in the car interior. In the Mazda model, check the sunroof fuse).
6. If the fuse is good, remove the control switches located on the overhead console. Disconnect the electrical wiring from them. Turn on the ignition and check the voltage at the switch terminals. There should be voltage at four terminals. If there is no voltage, check the supply voltage and ground of the drive. If the drive power and ground are good but there is no ground at the switch terminals, replace the drive. If there is no supply voltage to the actuator, check the ignition relay and the wiring between the ignition relay and the actuator.
7. If there is power at the switch, disconnect it. Check for contact between the switch terminals in all positions (figure 27.7).
8. If the switch is working properly, connect it. Find the ground wire of the switch and connect it with a jumper

9. The hatch can be closed manually. To do this, use a socket wrench to rotate the electric motor shaft clockwise.
