Dash air 1996 Fleetwood storm

[Tile_man]

1996 Fleetwood Storm. GM P30 chassis. Dash air stopped working. Connected 12 volts to pressure switch. Pressure switch works, compressor works. Checked compressor, high and low pressure perfect. I think it's a fuse or relay. Removed dash to access GM fuses. AC fuse not there. It's not in the front fuse panel in front behind the hood. Does anyone know where the AC fuse and relay are located?

Thank you for the reply. I checked the location you mentioned. No trinary switch. I also checked under the engine cover. No luck.
