Default AC Master switch on dash

Can someone tell me where the relay is that "AC Master" switch (front) on the dash of a '93 WB40 activates? I have power on breaker in AC panel but the dash switch is not functioning.
Thanks,
Terry

Hi Terry,

On my 91 the three A/C Master switches control three relays that are inside a 12” X 12” galvanized steel box in the “rear component panel” under the carpeted floor of the rear closet.

Note: The A/C Master switches just supply the ground for the relay coils.

According to the schematic for a 93 WB, the +12 VDC for all three relay coils comes from a “manual reset” circuit breaker "SK14" in the “rear component panel”.
