A/C: Is it my fan, my compressor, or what?

**duncan_sheek** · August 22nd, 2005 08:12 PM

bro, thats exactly my current problem... this weekend lang nagloko aircon ko. when i start the engine & aircon, minsan wala akong naririnig na click na nag-indicate na on na ang a/c, parang fan lang & after some time while driving, gradually lumalamig na but not as cool as before... what should i tell the repair guys pag nagpunta ako sa shop? thanks.

Had it check, wiring lang pala ang major problem. Madumi yung socket ng wire na nasa may bandang check-valve. Kaya naman lumalamig after a while is because the fans just kick in after the temp goes high.

Otherwise, yung dapat na pag-on ng fans kapag turn-on ng aircon, hindi gumagana kasi madumi yung socket.

The freon is just a bit low pero wala namang leaks na nakikita. The pressure in the hoses is constant.

Had the freon re-charged nga lang for assurance. Yun lang. Seems ok na ulit.

That is sana. I hope I didn't get ripped off. Or kailanganin pa ng mas malaking repairs.

pag ganun chinecheck usually fuse at mga wires going to the compressor. Paminsan naman yung thermostat switch ang sira.

[I]humming sound sa hood? bka ur compressor needs replacement na worn bearing n un mlamang at kung erratic ung paglamig worn clutch plate na kya minsan nka engage or vise versa. check m rin thermostat ng aircon ang gli prone sa pagloloko pag luma na. dont try to overhaul the cmpressor magttpon k lng, buy new or surplus na my warranty pra safe ka. check also kung tama idling loko2 ung mga ngdsign ng mdel n yn evrytme nag drop ng blow 6- 700rpm ng sshotoff ang cmpressor pra daw dka mmtayan, ang tnong e bkit m nman ibaba? mgttipid k gas? hehe

2 weeks ago lang ako nagpalinis ng aircon, replace filter/dryer & check valve... but when i brought my car to the shop in boni for a tune up, dun na nagsimulang magloko aircon. i dont know kung yun ang cause, during tune-up nilipat ng mekaniko ang hose from the carburetor sa isang vacant tube na nasa carburetor din bec di na daw gumagana ang tube na yun and tumaas ang idling. before the tune up ok naman ang aircon or talagang timing lang na nagloko ang aircon ko regardless kung ginalaw ang carburetor ko o hindi... by the way, my ride is ae92 1.6. and my problem is similar to astorath. Thanks guys.

from my experience and from what I know from the threads usually pag nagpalinis doon nasisira..

Kaya wag na lang palinis hanggat masira na lang. Yung honda hatch ko before never ko pinalinis (4 years).. binenta ko maayos pa.

yung bubbles sa sight glass is not applicable diagnosis sa r134-a system, para sa r12 system lang yung diagnosis na pag me bubbles ay low charge kaya yung mga 134a system karamihan ng receiver drier ay wala ng sight glass. for info lang ho.

pasakay naman sa thread.

problem ng aircon ko is, bigla na lang nawawala yung lamig (blower na lang). specially if maiinit sa labas. then after a while babalik din yung lamig.

pag hindi naman maiinit, like early morning and at night, ok naman yung lamig nya.

ano po kaya problem ng AC ko?

over or undercharge ng refrigerant will cause the same problem, pa check mo muna yung charge kung tama.

on mo ang aircon then check yung fan kung gumagana, minsan kasi hindi gumagana or intermittent ang operation nito kaya intermittent din ang lamig ng aircon, dapat every time magon ang aircon(engage ang compresor) andar din ang aux fan ng aircon at pagmalamig na compressor will disengage ang auxfan mamamatay din, pag hindi gumagana ang fan check connection or replacement na ng aux fan, ganito ang nagyari sa akin palit nalang ako ng bagong aux fan kila mang mario 2500pesos ang bill ko.
