Aircon loses cold intermittently

[robgowild]

Guys I need your advice regarding my car's aircon. When I switch my AC on to auto climate it will go in full blast and go cold with no problems. Now when its cold in the car na I tend to put down the power to 1 or 2 then after several minutes I will feel that only air blows out and its not cold. When it happen I will switch back the AC power to 3 or 4 and it will start to blow cold air again. When I did that I sometimes see white smoke/mist from the AC for a short time.

I'm planning to have it serviced soon but I just need your thoughts and opinions.

I'm not sure but probably the problem is ur expansion valve where it is not actuating properly. The EV sometimes working fine at the beginning when your A/C was turned on but tend to close prematurely due to frosting in the evaporator. That is why you see such mist coming out from the blower, this is a sign of a large quantity of freon is entering your evaporator.

Its a mazda 3 2006 2.0. Actually sinisilip ko yung compressor kung nawawala ba yung pagka engage ng compressor clutch pero di ko masilip since nasa pinaka ibaba.

Nararamdaman ko lang kapag nilakasan ko yung AC to bring back the cold is parang may manginginig saglit just like switching an AC for the first time.

Magkano inabot pa ayos mo sir? Did you replace the expansion valve?

Tungkol sa EV, don,t tell it's EV issue. Let them evaluate first and decide then saka na kayo mag suggest if ever wala silang makita. Be careful sa mga service minsan marami silang sinasabi na dahilan pero simple lang pala ang problema baka simpleng thermostat failure pala. Anyway Good luck.
