My Fiat Stilo has started intermittently blowing cool air through vents when set to hot temp. Also, this morning the tem gauge (which is normally static when warmed up) lit up red and indicator went to high with message to stop and turn engine off as too hot - I was on motorway so slowed down and it went back to normal. Any idea what the problem is? I had it serviced & MOT about 6 weeks ago
so should be ok.
