sir. we have the same problem. malamig ang ac namin, but kung nasa traffic at idle ang kotse (sometimes kung tumatakbo ang kotse), nawawala ang lamig, i just turn off the aircon. after 5 to 10 minutes. on ko ang AC, ok naman, what is the problem of this? pls help
pinalitan ko ng bagong aux fan last october 2011. last ac cleaning last april 2010 (change drier) and cleaning condenser etc.

December 12th, 2011 11:19 PM #12Sir, try mo pa-check ung pressure switch ng ac system mo. Kaya nga ung ibang mga mekaniko inaalis nila ung switch kasi paglampas mo lang ng konti sa pressure limit ng switch, ika-cut off na nya ung buong system. Which is good sana kasi it will protect your system like compressor, seal, etc. from over pressure. Pero ang problema lang, kokonti mekaniko lang ang may-alam kung paano mag-diagnose ng ganoong mga problem. Kaya sometimes short-cut na lang ang nangyayari which is the easy way by removing the pressure switch.
Sana makatulong ito Sir, marami salamat..

if i let the mekaniko remove the pressure switch baka masira ung system ko like compressor etc

December 13th, 2011 09:26 AM #15Usually kasi Sir over pressure occurs pagka kulang ang ventilation ng system like during traffic, idle, etc. Unlike pagka normal ang takbo, marami hangin ang pumapasok. Or in the other hand, baka may barado sa system. Anyway, Sir try mo dalhin ung car mo sa AC shop then ask them to conduct pressure test sa system mo. Alteast malalaman nila dun kung nago-over pressure pa ung system mo. Pagka ganoon nga ung result, medyo matrabaho nga lang ung gagawin kasi baklas lahat then pressure test each part like condenser, evaporator, etc.. Pero kung ok naman ung pressure, try to disconnect the pressure switch, then observe for a meanwhile kung ano magiging result. Don't worry Sir, din naman sya makakasira kasi sandali lang naman. For testing purposes only. Ung iba nga mga Car wala na mga pressure switch pero it runs the system very well.. Pero truly not advisable..
Sana makatulong ito sayo..

Sir baby_scar, one year na pala mahigit nalinis ang aircon ng iyong tsikot kaya ipa check po muna nyo ang inyong evaporator baka barado ng mga dumi kaya nag ice at yan ang dahilan na e trip ang compressor ng thermostat.

January 15th, 2012 07:48 PM #20hi sir, try nyo po p check ang mechanical thermostat at yung a/c relay. pero advice ko lng po kapag ang expansion valve at drier e
tumagal n ng 3 years dapat ay pinapalitan n po natin, wag napo nating antayin n mag bara ang expansion valve.. or kung every year
ay nag papalinis naman ng evaporator e dapat pag dating ng 2 years or 24 months ay palitan ang drier para m protektahan ang exp.
valve at hndi mag bara, advice lng din po wag po nating aalisin or i cut ang pressure switch sa dahilan ito po ang nag sisilbing breaker ng compresor kapag nag hi pressure ang a/c system. salamat po sana makatulong sa inyo po...
Puwede i try, 1. Palit air filter 2. Linis throttle body 3. Linis MAF sensor 4. Check spark...
high idle RPM at engine start
