heaters blowing cold

[carter-172]

hi, ive just bought a ph2 172 , when i put heaters on all they blow is cold air , but the temperature gauge on the dash is saying the outside temp is over 50 degree which is obviously wrong lol but sometimes the temp gauge disappears and the heaters work , but as soon as the gaugue comes back on they stop again plz help thanks dane

Turn it off auto, make sure AC light is off, put temp up, turn fans up.

Should blow hot air then.

IIRC outside temp doesn't effect the climate control anyway.

On a saxo I had in the past, the heaters only blew cold air after my radiator got fractured so maybe it could be your rad.
