ano kya problema ng aircon ko bkit twing i-on ko aircon ko bumababa yung rpm ko

**boybi** · September 21st, 2006 09:42 PM

hindi ba dating ganyan? usually bababa talaga ng konti ang rpm because of the added load kapag nag-ON ang aircon. pero konti lang dapat.

kung malaki ang binaba ng rpm mo, baka malapit ng mag stuck up yung compressor mo and the engine is having a hard time turning the compressor kaya malaki ang binaba sa rpm.

Kung efi ang unit mo e sensor or ecu ang may problema dyan. Kung lancer singkit yan e servo or trottle body may problema dyan.

one of the solutions can be, if that is carburated one, attach a "step-up" inaangat niya ung idling ng engine once na i-turn on mo yung aircon...

toyota xe unit ko, carburated. d kya yung equator ko yung problm. tsaka what meant pla dun s bumama yung rpm is yung tachometer reading ko. d b dpat pumalo pataas yung tach ko kya lng yung akin bmbgsak kpg ngaircon ako. can i mechanic solve this or i should bring it to a aircon specialist?

go to a trusted mechanic first to let him rule out compressor problem. kung compressor daw talaga ang may problema, tsaka ka pumunta sa aircon specialist.

check mo muna yun idle up/vacuum switch mo. it should work when you turn on your a/c. this would compensate for the added load of your compressor. if you can't find it take it to a reputable aircon shop ike mang marios or the bankers in marikina.

bro, ang problem po ng aircon mo is the fan . hindi po sya humihinto sa kakaikot, kaya malamig ang radiator mo. based po kasi sa experience ko, ganyan ang problem before ng car ko. kumusta naman po ang aircon? malamig naman ba ang labas o mainit na?

pakiramdaman mo kung sinasalo ng idle up mo once umikot

ang compressor mo. if not pa-check muna sa mech ang idle up

as sir boybi said. 2nd option lang ang a/c shop.

not sure lang kung pareho a/c system ng carb and efi. pro meron ako corolla GLi dati, ganyang-ganyan ang problema. napansin ko may leak (hangin) sa tubing papunta idle-up. pag tinakpan leak (or better yet palitan yung tubing), normal na sya.
