Air con Problem

[MAXBUWAYA]

97 Lancer GSR
(with cup holders)

1. At night time Malamig everything seems ok

2. Morning/afternoon under the sun on a stand still Sobrang init parang walang aircon

3. Morning/afternoon on good trafficc medyo may lamig

What could be the problem?
What are the parts to be replaced?
How much?

[BlueBimmer]

your aux fan could be busted...

[wakin]

probably me pin hole leak yan. ganyan din yung symptoms nung revo ko. me nakita silang leak sa fittings ng compressor. pinalitan lang ng rubber bushing nung fittings ok na.

[artpogi]

looks like a dying compressor

pa test mo muna compressor mo, ideal reading should be

on the low-side is 30-40 psi
on the high-side should be less than 200 with engine idle

if the low-side pressure is more than 40 and the high-side is still less than 200, maybe theres a problem with the expansion valve or compressor,

if the high side reading is 200+, that's what they call high pressure

HTH

edit: I'm assuming here your A/C system has no leaks

Sounds like the aux fan. Surplus is Php1,500 + a lil labor for install

Can also be a dirty condenser or an a/c comp that is not compressing like it used to.

sir, favor naman, could you elaborate? what are those pressures for? i just had my aircon cleaned, sinabihan ako before cleaning na high pressure, pinakita sakin na umaabot ng 200psi. after cleaning it was below 200, 150 ata yung nakita ko then 30-40 yung kabilang side, problem ko naman, the aircon wasn't cold as before. medyo "hilaw" yung lamig eh. do those pressures have something to do with the coldness? ibabalik ko sa kanila, under warranty pa naman eh, just wanted to know para di ako mukhang tanga

first of all I'm not an A/C technician, I was informed by my A/C tech friend about those readings.

IMO, basically what it meant is that those should be your pressure readings if your A/C system or part of your A/C system is in tip-top shape. Now if your readings are within those that I posted then I guess it is okay.

I have encountered the same problem as that of the thread starter and remember having my A/C checked and can't find no leak and the aux fan working fine, when we checked the readings it was not within the ideal range, so we deduced that the A/C compressor was on it's way out, true enough, when I replaced my compressor, everything turned back to normal

As for the "hilaw" na lamig after cleaning, it had happened to me and I have no answer for that, that is why now, if my A/C is working fine, I don't let anybody touch it, I don't have it cleaned unless I can feel that something is amiss. That's why when it comes to my A/C system my policy has always been "if it ain't broke, don't touch it".

i share this view. ganyan nangyari sa singkit ko dati eh. dahang-dahang namamatay. compressor failure. when i had it replaced, balik dating lamig.

[MAXBUWAYA]

ARGH! Magakano kaya compressor?

Surplus or Brandnew? Replacement or orihinal?


given all your suggestion

the dillema now is finding a mechanic that would pinpoint exactly the problem
I dont wanna to do trial and error. Baka magend up ako na pinalitan na lahat.

Tnx s mga suggestion.

I hope its got nothing to do with my cupholders

maxi...its somewhere from 10k-13k..
syempre, brand new. you can never go wrong with it. minsan kasi sa surplus, after a month or two, pwedeng mag break down ulit, mag dodoble pa expenses mo.

mechanic? si mang mario.

may connection ba yung cupholder mo sa aircon system mo? kasi kung meron, baka yun nga ang culprit. hehehehe.

or you may try calling up Coolmate, which is a service arm of Denso (Denso aircon ng Pizza eh.) based on the brochure that i have from them they can rebuilt compressors, which are quality guaranteed, using original abd nrabd new shaft seals and gaskets. Those parts which are out of specs are replaced with brand new parts.

branches:

Makati - Pasong Tamo Extension (867-3218)
Alabang - Motortown, ATC (8091924)

Pa check mo muna sa kanila. May free checkup services sila.

hth.

Kung compressor iyan, you will also need a new drier. Pinapackage deal ko na lang kay Mang Mario yun. Lahat na kasama labor. hehehe.

Php6,400.00 yung surplus Denso compressor bago tawad. Sila na maghahanap at magkakabit. 6mos warranty. Kakapalit ko lang nung sa Vitara. Galing pa ng Mitsubishi na sasakyan yung Denso compressor na kinabit. hehehe.

Yung surplus Denso ko dun sa Pajero, medyo matagal na din. Wala pa naman problema.

You can also buy a new compressor if you want to be sure. Kung kina Mang Mar mo ipapakabit, hindi pa din ganun kamahal ang labor. Meron naman siyang stock ng drier sa bahay. Yun nga lang medyo napalaki yung drier na nailagay sa Vitara. Yung pang Hi-Ace. Ok lang naman, same price din as the small one and wala namang naging fitment problems.

Have similar problem sa EK. nangyayari naman pag naka idle ang init tapos pag highway lumalamig. yun pala yung condenser fan nagloloko na. nung pinlitan balik na ulit sa normal.

[recklus]

hayz, any more sugggestions? 2 yrs old pa lang kasi yung kotse, medyo malabo naman po siguro na compressor. how about po yung freon? i saw na di nila pinuno, would that effect yung lamig?

[av427]

Gusto ko din sana humingi ng advise,

Yung car ko kse may warranty pa yung aircon, and lately napansin ko na bigla biglang humihina yung buga ng hangin sa vent, pag dinikit mo palad mo sa kanya malamig kaso yung hangin pahina ng pahina dahan dahan hanggang wala nang lumalabas na hangin.

Ginagawa ko, OFF ko sha ng 3 mins tapos pag bukas, NORMAL na ulit sha.

Nagtataka ako kse di naman laging nangyayari, siguro sa 7 days, mga 2 days nangyayari ang ganito pero once na OFF-ON ko na, okay na sha.

Kapag nangyayari ito, wala naman traffic at di naman tanghaling tapat, basta basta nagsusumpong.

Nagexperiment ako at ginawa ko na pag upo ko sa car, todo #4 agad ang fan speed, temp is coldest. Then after 1 minute nilalagay ko na sa #1 yung fan speed which is my normal setting kse malamig na sha sa #1. Sa 3 days na ginagawa ko to, di naman nagloloko ang aircon kaya obserbahan ko pa mabuti.

Dadalin ko sha for warranty replacement of parts, pero gusto ko sana itanong muna kung ano kaya ang diperensya nito? Baka kse mamaya kung ano ano palitan nila yun pala di naman yun ang defective, eh kailangan ko yung auto everyday sa work.

Advise naman po dyan

baka yung mismong aircon blower/fan. kung malamig, hindi sa components yan. pag mahina ang buga, sa blower.

av427,

bro pa check mo din if may butas na yung evaporator. happened to me already. advise lang if magpapalit ka ng evaporator, ipalit mo yung laminated type. i've already tried all from the fabricated (yung mga tubo tubo lng grabe init nito pag tanghali ) serpentine type ( ok siya kaso matagal nga lang lumamig) at yung laminated (Eto ok).

[av427]

Hindi kaya defective expansion valve ang problem? Bago pa kse etong auto ko kaya nagtataka ako

[huangyenhao]

Hi all,

this problem also happens to my brand new innova.

i noticed that the aircon is not so cool sometimes in the morning, when under strong sunshine, but back to normal after few minutes.

in the night time, it rarely happened

i did go to aircon repair service for free check up and i saw the meter was jumping back and forth between 40~60 psi when my car was in idle.
technician told me the normal should be 40 psi.


after check up, i also went to toyota shaw to have quick check up, technician just changed the wiring thing and the problem seemed to disappear, he just told me to observe for more days.

for these days the problem seems to be gone but i'm still observing, will report the problem during my 1k pms.

[av427]

Hi huangyenhao,

Yung sa yo ba mahina din ang buga ng hangin palabas?

Pero pag dinikit mo yung palm mo sa vents eh malamig naman?

Yung akin kse pag sumpong, pahina ng pahina hanggang wala ng lumalabas halos tapos pag pinatay mo for 3 minutes ang aircon then ON ulit, okay na naman sha, malakas na ulet.

Ang hirap kse pag nasa kasa ako,ang lamig ng aircon di ko tuloy maipakita sa kanila yung problem, hindi kse madalas sumpong nya, kaya gusto ko sana dumalas para madali ko maipakita yung problem sa mga taga kasa.
