Operation CHARM: Car repair manuals for everyone.

System Operation

A power sun roof (CF5 option) is available with the following features:
^ A sliding window panel
^ A manually operated sunshade

The power sun roof will operate with the ignition switch in ON and for an unlimited amount of time once the ignition switch is turned to OFF, until any door is open. The sun roof control module has it's own internal retained accessory power type feature. Once the sun roof module detects the sun roof ignition supply missing (ignition OFF), the module will still allow continuation of sun roof operation. The sun roof will be operational until a low signal is detected on the door circuit. Any door opened at this time will disable further operation of the sun roof, until the ignition cycle is activated again.

The power sun roof is electrically operated from a rotary switch that is part of the sun roof control module. The rotary switch is located in the center of the windshield header area. The sun roof switch being a rotary (potentiometer) type switch will allow the sun roof glass not only to be able to move to the positions listed below, but to any position in between:
^ Express Open
^ Express Fully Close
^ Express Vent Open

Express Open
To open the power sun roof, turn ignition to ON, rotate the sun roof switch clockwise to the last setting. The sun roof glass will slide open as the glass slides in between the roof and the headliner. As the sun roof glass slides open so will the sunshade. During this operation you can turn the sun roof switch to any other position to stop the glass in a desired position.

Express Fully Close
To close the power sun roof, rotate the sun roof switch so it faces towards the front of the vehicle. The sun roof glass will slide to the fully closed position unless the switch is rotated to a position other than fully closed to stop the glass in a desired position. To close the sunshade, this will have to be manually slid forward.

Express Vent Open
To open the power sun roof to the vent position, rotate the sun roof switch counter clock wise. The rear of the sun roof glass will raise slightly to the vent position. To open the sunshade, this will have to be manually slid open.

Anti-Pinch
If an object is in the way of the sun roof glass while closing, the sun roof glass will stop and depending on the position of the sun roof glass, it may reverse back open to a preset factory position.

To temporarily disable the anti-pinch guard, press upward on the sun roof switch as it is closing. This will override the system, allowing the window to continue to close. Once the switch is released the anti-pinch feature is enabled. The sun roof can be closed manually if a failure in the power supply occurs or if the sun roof cannot be closed by using the sun roof switch. Refer to Manual Sunroof Description.
