HVAC blower wiring schematic

My 1995 Ford motorhome blower does not work. The motor works fine. All threads say to follow the circuits to troubleshoot. That is nearly impossible with wiring harnesses. I need a Ford F- Series HVAC wiring schematic to find ALL of the electrical components, in order to test. Please help.

Blower motor relay

My 35' Pace Arrow is built on a 95 F53 460 Chassis. It does not appear to be the Evans HVAC system. I have purchased three separate ford wiring diagrams. The all show completely different color codes. My system 12v main power to the hvac system is Blue wire w/ red stripe. It goes directly to the Blower relay pin #87. The blower motor has one blue wire and one blue w/white stripe. All of the wiring diagrams show brown/orange and orange/black wires. I am gettin very frustrated.
