there's this unusual sound that emits when i turned my car's aircon..parang pumipito? ano kaya ang cause nito?

another thing, pag start ko ng kotse parang may "tsittt" soundpag click ko ng susi sa starter? ganun din pag off ko minsan may parang pahabol an redundo..ano kaya cause din nun?

tssit?? baka may chicks ka dyan sa loob ng makina at tinatawag ka.. eheheh... kaya siguro pumipito rin.. type ka nya...:P:mrgreen:

hehehe.. pahabol na redondo, myt mean that you have a rich mixture.. may naiiwan na gas elements pa sa makina pag switch off kaya ayun.. parang pahabol na redondo. Itlog Lancer kotse mo di ba? when was the last time you had your car tuned up?? as for the aircon, marami pwedeng tumunog na parang pito dyan... it maybe your blower (bearings are shot)... or baka may slow leak ka somewhere (which i doubt... unless nauubusan ka ng lamig)....where exactly is the sound coming from?? sa vent? sa gitna? sa tabi? sa may engine compartment?

pito could be the expansion valve of the a/c, that's probably the sound of refrigerant hissing through it.

tsitt could be a spark in your starter solenoid contacts. baka malapit na bumigay yan contacts ng starter mo.

pahabol na redondo could be "dieseling". may hot carbon particles sa loob ng cylinder and this serves as a glow plug and it ignites the remaining fuel/air mixture kahit off na ang ignition system. check your spark plugs, if it's coated with a lot of carbon then that could be it. maybe.
