Need help (intermittent ON ang compressor)!!

**karlos** · February 4th, 2012 03:21 PM

Mga sirs patulong naman po sa problema ng a/c ng car ko. Dinala ko po sa a/c shop ang car ko kasi walang lamig at sinabi ko patay ang compressor pero minsan gagana kung ginagalaw ko yung relay ng a/c. ang sabi ng technician, kulang sa freon at may leaks sa tubo at sabi nya hindi dahil sa relay kundi dahil walang freon kaya yung presuure switch, hindi gumagana. so ang ginawa, nilagyan ng freon at pinalitan ang o-ring. after that po, gumana naman po at malamig naman. after few days, ayaw na namang umandar yung compressor, so binalik ko sa shop. This time, sinabi sira ang relay, so pinalitan nga then gumana naman. After a day uli, ayaw na naman so ibinalik ko uli, then this time sinabi na sira yung pressure switch. Posible po kaya talaga na yun ang problema? hindi po ba ma check if sira talaga pressure switch kasi parang trial and error lang nangyayari. If palitan po, normally magkano po kaya yung part na yun?
Quote po kasi sa akin 1400 parts lang. Nissan exalta po 2002 ang car po.

marami pong salamat.

this has a multifaceted scenario:
1- the technician does not really know how to properly diagnose the symptom
2- the technician is not properly trained and equipped
3- the technician tries to please you by not replacing all the parts needed to repair the problem and hopes to make you save money
4- he thinks that if you replace more than one part (mulitple part failure), you might go to some other shop
5- he tries the "wait and see" approach if you come back with the same symptoms
6- he probably wants you to come back some other time
7- he wants to see you again, hek hek

diagnoses are supposed to be thorough regardless the real estimate for parts and labor hurts. if you go to a competent shop with competent technicians that is decently equipped, you always most of the time, thinks the charges will be high. most of the time if not all, you get what you pay for. this situation is more inconvenient and probably a more expensive proposition since the guesswork or "diagnosis" is wrong and is nickel and diming you

sir i will try to explain(with my understanding off course

) the purpose of a pressure switch in your a/c system
it is there to cut out the compressor when the system pressure is below its specified limit,this is to protect the compressor from being starve of its lubrication, this switch is usually located sa receiver drier/accumulator,ok, meaning kung kulang ang freon mo mag off ang pressure switch mo leading to no power to your compressor magnetic clutch its sort of like a switch na ka on pag may tamang pressure off pag kulang ang pressure, there is a way of testing this pressure switch at your own risk nga lang, and make sure na tama ang amount ng freon mo sa system ,ginagawa ko ito sa car ko ,engine idling a/c on un plug the pressure switch connector ,the compressor magnetic clutch should disengage this usually means ok ang switch but not always, now if you could simulate the fault, engine idling a/c on compressor clutch not engaging pull out the pressure switch connector and short the two terminals with copper wire the compressor clutch should engage then you find your pressure switch to be defective ,again make sure you have a proper amount of freon level in the system., sana natulungan kita
