aircon, cold then warm

[cokezero]

can be na nag hi-high pressure na ac system mo.
check aux fan relay kung gumagana,
or the aux fan itself, if mahina na ikot, palitan na.
check mo din yung freon level sa drier, if bumubula bula na, bawas na ng freon. recharge nadin na.

madami pwede cause nyan e. pwede ice sa evaporator, kulang sa charge, sira ang expansion valve, barado na filter-dryer. patignan mo na lang pare ko para di tayo nanghuhula.

una kong titignan diyan is kung gumagana pa ang auxiliary fan sa condenser. nangyari na sa akin yan dati, pag check ko may naipit sa fan ng condenser so stuck up yung fan plades. nung tinanggal ko yung nakabara and umandar na yung fan, solved yung problem.

salamat sa mga reply..
btw walang aux fan nanakakabit sa oto ko,

gusto ko lang malamang yung mga idea niyo para if ever ipa check ko sa shop alam ko na yun yung papalitan
baka kasi sabihin palitan ganito ganyan pero sila rin nanghuhula lang )

Pwede naman lagyan yan, mas makakabuti pa sa ac system,
i-tap lang sa aircon pag nag-on sabay bukas, or separate switch/manual ang bukas.
hindi hirap ac maabot yung nakaset na temp sa thermostat and
less prone sa pag-hi-high pressure.

yung iba nga, dalawang fan pa ang nilalagay. (fx puv kadalasan)

we currently have an old school ride, 70's car,
and long time ago pinlagyan na namin ng aux fan para makatulong sa ac,
manual switch, so far so good.

your choice sir, if ayaw ng aux fan,

those what mentioned above might help. goodluck!

[sotel]

sir kailangan paba mag add ng relay kung magdadag ng aux fan ?

[yebo]

kaya nga di ko nilagay yung aux fan sa possible causes kasi isuzu tfr ang vehicle, belt driven radiator fan yan. kung lalagyan mo ng aux fan di rin maso-solve ang problem nyan kasi di naman yung fan ang sira.

[kompressor]

kung walang aux fan, how about the fan clutch? maayos pa ba operation? stock na 7k tamaraw fx wala ring aux fan pero pag naka aircon, ramdam ng fan clutch yung init from the condenser and mas kapit siya compared sa pag aircon off na parang lumuluwag pag sakto na sa operating temps.

[yebo]

sir kailangan paba mag add ng relay kung magdadag ng aux fan ?

may relay na para dun sa air con compressor clutch, i-tap mo na lang. most relays naman more than 1 ang terminals kaya pwede mo gamitin yung relay na existing for more than 1 function. dapat lang e alam mo kung alin terminal ng relay yung i-tap mo.

mas alam pala ni sir yebo, TS, do follow what he suggests, might help you more than what i suggested.

AFTER, if you still think na your ac system needs some aux fan help, walang masama lagyan, mas makakabuti pa nga.

your choice sir.

Your auxiliary fan, supposing its still in optimal working condition, should be fine. If it shuts off too soon, then you'd notice your engine temp to spike as well. This is assuming your condenser is in front of your radiator.

But since its crank driven, your issues migrate to something more along the A/C's subsystems.

The problem in those situations normally have more to do with your refrigerant levels. If after a full charge and this is still a problem the A/C's internals may need to get some work done.

it would greatly help if you specified your suction (low side) and your discharge or head (high side) pressures when the symptom begins to show. this way, the numbers on both gauges tell you as to what is wrong with your system rather than guessing and hoping somebody will come across luck.

my old car (front engine-rear wheel drive, no aux fan) would default to fan in heavy traffic. i solved the problem by having an aux fan installed in front of the radiator. but you should have your vehicle seen by the aircon folks. too many possibilities, as the guys here suggest.

Before you dive into technical bits, try adjusting your thermostat a little bit on the warmer side. Your evaporator may be icing over due to your thermostat setting being too cold.

That, or you need to have your refrigerant levels checked.
