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.

ditto on the expansion valve.....

[testament11]

Same problem tayo sir. Kakapa-ayos ko lang nito kanina at ang problema ay expansion valve.

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.

Yes that's what I will do. Actually na experience ko na mga shop na ganon, dami sasabihin na kailangan palitan tapos sasabihin pa na mahal daw piyesa sa ganung sasakyan. Since most of here suggest its the EV, I hope the shop figures the same. Punta na lang ako sa CeeJay since they have good reviews here. Thank you for the advice

Pakishare na lnag din kung anong findings for future purposes. Thanks!!!

pede nga sir wiring ang problem nyan sau kaya nanginginig un kasi umandar ang compressor,. un ang kailangan makita kasi jan kung umaandar ang compressor., kasi kung ngloloko ang wiring ng compressor kahit mgpalit ka ng valve mawawala pa din lamig nyan., ingat lang sir baka kung anu ano nga ang sabihing sira nyan., pedeng simple ang sira talga nyan palalakihin lang nila ang sira kaya mgppalit palit talga sila ng pyesa., kung valve din kasi sira nyan di na tlga lalamig yan kasi barado na pwera nalang kung di ngloloko ang termostat,. kaya check mo din kung ngautomatik sya pg malamig na,. mas mganda yan kung papacheck u ung alang lamig para kita nila kung ano talaga ang sira.,

Thermostat po malamang problem nyan... Ganyan din po nangyari sakin... Hindi ko maadjust sa tamang temperature na gusto ko... Parang on and off nalang ang nangyayari.. Lilipat ko sa 3 or 4 pag nainitan ako pag nalamigan na ako bababa ko lang ng konti at pag binaba ko kahit konti ang thermostat hindi na mag eengage ang compressor kahit sobrang init na sa loob...

[jojomonsalud]

Parang ganito nangyari sa akin kanina, pero sa akin yung blower ang humina. Nasa number 4 pero halos walang nilalabas na hangin.

Tapos sinubukan ko i off yung acu. Ayaw na bumukas ng blower. Pero after 5 minutes nag on na ulit siya.

Last na acu cleaning last Nov. Vios 2010/g po yung ride

Why are filipino drivers obsessed in having the evaporator removed and cleaned? Most if not all a/c shops in the country do not have a vacuum pump. They use an auto a/c compressor as "vacuum pump" and it cannot pull deep vacuum of 29.8 inches of mercury resulting in moisture and/or non condensible gases (NCG or air) in the system

^ * jick.cejoco - not really obsessed but it a "must" be cleaned the evaporator. Mala deserto kasi ang hangin dito sa manila eh. LOL

because it's big and they can see the guy working, sweating on it and they feel good that they are getting their money's worth and it gives them the feeling that meron silang alam kahit papano...
and they read somewhere or binulungan sila, that evaporators need regular servicing...
AND, it's not as expensive as the compressor..
heh heh heh.

but whether that evaporator really needed servicing at that point, is something else.

many shops now use legit vacuum pumps.. but not many use refrigerant extracting machines.. they still vent it on a bottle with water..

what i do notice on all shops is that they do not weigh the refrigerant charge instead they only use pressure and the sight glass as basis whether the system is full or not.

re the evaporator pull down for cleaning, air in the metro is so polluted that evaporators get clogged up with dirt and carbon that manual cleaning is necessary. ive seen used evaporators from japan and they are not that dirty compared to used evaporators here in ph.
