Roof AC Miramar

[cgracing]

My main room roof ac will no longer engage on the high fan setting. The compressor comes on and gets cold on low. The fan will not work on high in either the manual fan or auto setting.

Rear AC works fine. This was functioning fine on previous trip. Any suggestions were to start troubleshooting would be great.

Thanks.

Remove the tstat and see if a wire or two is loose or broken.
