boybi,
I think naka on na recirculating air bago buksan yung auto climate control kaso kusang lumilipat sa fresh air mode.yung exalta din ng future sister in law ko ganun din problema.Common yata sa mga exalta.
by the way bro, since your not mechanically inclined suggest ko to buy a brand new or almost brand new car, mga 1 to 2 yrs old ok na.Based on experience ko kasi before in buying 2nd hand cars I end up spending more sa repairs. Well needless to say Ive learned my lesson na kaya I dont buy cars which are more than 2 yrs old.
