Hi bros, so my Vios ncp93 experienced hot air blowing out from time to time and so just 2 weeks ago I went to my workshop to check on the aircon system then I had my radiator and coolant replaced to brand new by e workshop. After subsequent 5-6 days the aircon start blowing hot air again, this time round wkshop say cooling coil problem, and so, I had the cooling replaced to brand new and top up gas too. Checked compressor by wkshop say no issue. After cooling coil replacement, aircon gets super cold and strong, quite happy abt it.
Just a couple of days ago and today as welll, the air con started blowing hot air again. The strength of the fan is there but not cold at all...
Now really jin headache, what could be the issue??? Since I ald change cooling coil, radiator and compressor no issue . Really Pekcek ald spent so much $$$....
Could it be the thermostat issue..idk.. please advise me! Thanks!
