My daughter's prius started blowing less than cold air and displayed a "check air connection" message no the MFD i tried to run the AC diagnostic mode but apparently the steering wheel recirculation button isnt working so i couldn't get into that mode..... I'll run techstream tonight but wondered if there is another way
Techstream is the other way. When you get around to working on the other problem that got in your way on this problem, there is a 'switch check' screen available on the MFD that you can use to see what dash and steering wheel signals are working, if you'd like to get that sorted. Could turn out to be a spiral cable issue, maybe.
