Solution: change A/C shop.

Your problem might be a slow leak somewhere in your A/C system. The shop will have to take apart your A/C system and do a leak test on every part.

try mo muna palitan ng manua thermostat mura lang naman ito cost 350petot lang,, baka nag mamalfunction na ang thermostat mo kaya minsan me lamig minsan blower lang,, try mo obserbahan pag namatay ang thermostat i mean compresor ilang minutes bago sya bumuhay ulit? or baka kailangan mo pa tapakan ang gas pedal para bumukas ulit ang compresor

[sboogie]

check mo rin yung magnetic coil ba yun ng compressor

yan kasi naging problem ko dati nung nagloko rin a/c ng corolla namin dati

maaring di masyado na vacuum ang system nung linisin ito,kaya may natirang hangin na sumasabay sa freon, na pag nagcondense ang freon magco-condense din ang air sa loob ng system at pag dating sa expansion valve pag nag evaporate ang freon para lumamig di na nagagawang mag evaporate ng air na naging moisture magyeyelo na sya dun nagiging dahilang ng pag bara sa expansion valve.ito ang dahilan kung bakit nawawala ang lamig at kapag natunaw na naman yung moisture na naging ice sa loob ng exp.valve magsisimula na uli sya lumamig so on and so port

papalitan mo filter drier mo at expansion valve at pa vacuum mo ang system ng matagal para masiguro na moisture free ang system mo

ghosthunter,
as far as i know, leak tests are done with all components are installed in the system, this way you know if it was the joint fitting o-rings are causing the leak or the joint is not properly torqued to specs.

i totally agree with you jick .

i never done a leak test to the customers with this procedure .

technicians back home although highly skilled , were ill-equipped ,resorting to the conventional way yet not proper.

pag diretso lumalamig ulit? hindi kaya nasira fan nung a/c? ganyan po kasi nangyari sa sentra ko pag tumatakbo nahahanginan kaya lumalamig tapos pag tumigil wala na ulit hangin iinit na ulit.

pero kung ako lang padala nalang talaga sa a/c shop
