    you need to check your system pressures with a full load of refrigerant in it, if its low - you will come to know if your system is choked or compressor is not pumping at full, next comes your heat exchanging abilities, if you have a duff condenser or duff condenser fan - you will never get chilling at the evaporator coil, then the expansion valve needs to be working in top order to actually reduce the evaporator temperature to 0 degrees celcius.

    You may need to strip your dashboard and clean all the air ducts to ensure proper flow and while at it, check the electrical connections and the condition of the blower itself.

    a 12 blade curved fan in my Hondas stock radiator position works wonders to cool down the rad and condenser and freeze the interior in any sort of heat - running original 10 cylinder denso compressor on R12.

    Well i am using khyber from last 3 years... i also have had the same problem last year with ac colling...... well if the blower speed is not too much then obviosly u have to clean up ur cooling coil and also dashboard if its too old or dusty..... then for proper cooling ur compressor should be accurate as well as soundless.... the ac gas should be of good quality R14 one in khyber, the filter should be cleaned.... and the one important thing is the radiator working. i have had single channel radiator 4 years back but then i installed 2 channel radiator which now costs about 35,00 to 4,000..... the ac cooling becomes double, also try to chek if any gas leakage.....the gas pressure should be high.
    Ac wali jali ko b saaf krwana parta hai arar wo choak ho jay ya us k fan ki speed kam ho to b cooling effect hoti hai at low speed or jb gari khari ho

    IMO if your whole system is actually setup for R134 - then its worth it and make it absolutely sure that the thermopole barrier is intact in the evaporator housing..

    by cooling regards R134 is a POS gas - that refuses to easily heat up and cool down, unless your system is actually 20% over effecient for the car

    First of all get it serviced by an experienced AC wala.
    Check the gas pressure/leakage and the AC oil.
    For an increament in the blower speed you can connect a relay with your AC blower which will result in a better air flow.
    One of the most difficult things in the world is to know how to do something, and to watch without comment, somebody else do it incorrectly.

    Also keep you condensor clean so that air can freely pass through it.
    A clean condensor ensures good cooling in any car.

    Ok.

    1 - Change the stock Condensor to Multi Flow or Multi Aisle condensor of sanden that comes in new cars now a days, That will improve cooling by atleast 20 to 25% for sure, And over all load on cooling system and car will decrease this is tested
    The gas leakage problems will be solved as well because with Multi flow the pressure inside the system will not increase too much to develop leaks.


    2 - Get whole system serviced,

    3 - Install good quality Fan infront of condensor get corolla 88 FAN.

    4 - Use R12 Gas cools better than 134.

    If u want i can refer you to my mechanic he will do all this and car cooling will be geat but kharcha hoga :p
    Speed costs money, how fast can you afford to go.

    dear
    which system is installed in ur car.. genuine factory fitted or u installed later?
    If blow is weak, then check the blower speed, ducts.. if dust or speed problem. get it checked
    if all ok, but cooling low,,, then check gas pressure... or piping connections...
    if all works well,, get fron radiator checked if it is choked then cooling is usually affected..

    hello pakwheelers
    i hav khyber 96 senden compressor. the ac was serviced, gas checked b4 start of summer season. everything was working fine. just yesterday i suspected its not cooling. went to ac mechanic. he says gas needs to be refilled.
    he filled the gas but no good. he then said the filter n valve is choked ... will cost around 2500-3000/- he says this happens when compressor is weak n it backfires "kachra" which block filter n valve!!
    didn't quite get his reasoning?? want suggestion from you guys!!!
