Circuit Operation

The GAUGE Fuse is supplied with voltage when the ignition switch is in the ON or START position. Voltage is applied from the GAUGE Fuse, through the fuse block - instrument panel, to the relay control circuit of the P/W relay. The other side of the coil is permanently grounded at G200 and G201. With both power and ground supplied to the coil of the P/W relay, the coil energizes and pulls the contacts closed. The POWER Fuse is supplied with power at all times. Voltage is applied from the POWER Fuse, through the closed contacts of the P/W relay to the sunroof switch assembly. The sunroof switch assembly is permanently grounded at redundant paths to ground: G200, G201 and the sunroof motor case ground.
