So I've had problems with my AC and gotten to the point of it being the blend door. Does anyone have a FSM for a 93 fleetwood that could copy out the pages for the diagram for that to see if I just need to replace a relay for some mechanical way to switch it to cold only? I've opened up where the heater core is and everything but can't figure out what underneath there is going to be the blend door. Any help is appreciated!
