    Hi sirs. Need your comments about my aircon problem. I own an Isuzu TFR. I noticed that the A/C isn't that cold when the sun is up not compared when it is at night. And, the A/C is becomes cold when I drive in highways such as SLEX compared when I drive in EDSA or in the city which I tend to stop specially during traffic.

    What seems to be the problem sirs? I had my blower checked, added freon and the ducts are still clean.

    Thanks for the help

    Do you have an electric fan for the condenser? It's the radiator like thing outside your cabin where the heat exchange occurs. If the fan is slow, the a/c will not be as effective in traffic since there will be poor airflow.

    I checked if the fan in front of the condenser is working - positive. Are there different kinds of blower fans? My problem started when the blower fan had a problem and the only solution for it is replacement. Our driver bought a new one and had it installed.

    Sa tagal na din ng TFR madami na din dapat ireplace sa aircon parts. Dati din meron ako nyan. Bakit nung bago yan e wala naman nakainstalled na blower sa condenser e napakalamig? Kung napalitan mo na un evaporator at expansion valve and filter/drier at nahihilaw pa din ang lamig, I think it's time na magpalit ng a/c compressor, medyo madugo lang ang presyo especially kung bibili ka nung orig 7 piston sanden or denso(10K up), Meron din namang 5 piston type(5k to6K) na I think pede na din dahil maliit lang naman ang papalamigin sa pickup

    kulang ang buga nung pinalit na fan or mali ang flow ng hangin. tawag ng mechanic ko dyan kulang ng "ram air" kasi umiinit masyado ang condenser. yung mali ang flow ng condenser fan marami nagkakamali dyan.:D

    Ang paglalagay ng fan sa condenser e remedyo lang para lumiit ang gastos. Sempre may lifespan din yan condenser. Kung over 10 yrs na yan, di na masama kung palitan na din yan.

    Thanks sirs sa mga reply.

    i went to an A/c repair shop and here are the recommendations

    1. Palit po daw ng compressor from 507 to 508 na sanden (b/new P7500) kasi hindi kaya ng compresor palamigin lalo pag naka-idle lang

    2. palit po daw ng evaporator to "formula 3" type. yung akin kasi lumang model na.

    3. ayusin ang ducting

    Any comments on this sirs? If I may ask, ano po ba ang compressor ng Isuzu LS na pick-up ang yung type ng evaporator para lang ma-compare ko yung sa akin knowing that the TFR arrived in the Phils with no A/C. Thanks sa mga replies po ulit.
