My car A/C is driving me crazy these past few days. 'Eto yung nangyayari:

From cold start, I switch on the aircon (both fan and thermo control). May hangin na lumalabas pero hindi lumalamig.

Usually, when I do this, there is a humming sound coming from under the hood. Ngayon wala. When I popped the hood and checked. I noticed na hindi tumatakbo yung aux fan ng aircon ko. From my experience, kapag on yung aircon ko at idle, the aircon aux fan runs. Ngayon hindi.

I checked the belts din pero umiikot naman silang lahat, especially yung nakakabit sa compressor.

Not until I've driven the car for quite some time at uminit na yung makina tsaka lang babalik yung humming sound at lumalamig na yung hangin from my vents.

Someone advised me that it's the freon mahina na daw yung pressure, kaya kapag sometime after the pressure has built up dahil sa pag-andar ng makina at compressor, tsaka pa lang lalamig yun and magki-kick in yun fan dahil pressure switch daw ito kaya sabay mag-on sa aircon kapag normal at walang problema. Tama po ba ito?

Could you please advise me on the matter. I'd appreciate it.

My car's a 93 Corolla GLi. If you have ideas on what I have to get fixed baka pwede pa-advise na din kung magkano ang gagastusin. Medyo kapos kasi ako sa oras na pumunta sa mekaniko. Sana kapag pumunta ako, ready ko na din yung money para hindi sayang sa oras.

Salamat!
