Test B - Mode Selector Switch Test

Mode Selector Switch Test:

^ Backprobe the connector to the A/C Control Assembly and measure the voltage to ground with the connector still on the assembly.
^ If Battery voltage is not present at terminal E, check the BRN wire circuit back to the fuse.
^ If Battery voltage is present at terminal I/P, but not at terminal B, install a new A/C Mode Selector Switch.
