    Si Mang Mario nagbibigay naman ng diagnosis without necessarily having to take the system apart.

    Minsan test lamp at multimeter lang gamit nila.

    Sir KC,

    I have an ex JDM pajero Gen II. I also experienced the same problem, kaya lang pag nakatapak sa gas (recta) malamig. Pag traffic, umiinit na. Yup... mukhang aux fan di ba? Ok naman aux fan, i had it checked. May expansion valve pala sa rear aircon, at yun lang ang sira. After that, malamig na.
    Please check na lang, kung naka 'on' ang rear mo, if you hear any form of "humming" sound or noise from the rear aircon that is out of the ordinary. Pwedeng expansion valve! Hope this helps.

    Regarding temp. Pag traffic (as it sobrang trafic), my outside temp reading is around 40-42'C, pag normal driving bumababa sa 30-31'C. I think its normal. Also, tama si OTEP, engine temp ang cause ng mataas na reading, especially pag traffic.

    same symptoms with my besta. malaki hinihina ng ac pag naka ON pati rear, unless naka high rpm.. cause is mahina na ang aking compressor.

    Aircon kasi plays around with pressure. Usually, pag nawala ang lamig nabago ang operating pressure. May leak, magbabago pressure. Mali ang valve in terms of calibration, iba ang pressure. Sira aux fan, tataas ang pressure. Mahina compressor, mahina pressure. KCboy, malamang expansion valve yan. Baka malaki ang buka ng valve sa likod kaya humihina pressure ng valve sa harap pag-on mo. Subukan mo pa calibrate yung valve sa likod. Pasakal mo ng konti o palitan mo.

    zeagle,
    ask ko lang, tatapon ba yung refrigirant ko if they adjusted my expansion valve?

    EV's are usually replaced. Yes papakawalan ang coolant mo. Expect the whole thing to cost less than Php 2K. Labor, parts, materials na iyon.
