I just came from a smooth drive from Sta Cruz Laguna yesterday until my aicon suddenly lost its usual temperature. My suking repair shop's diagnosis said that "nag yelo" daw ang aircon. After putting the thermostat to full heating position, water flowed from under the vehicle. Since the vehicle did not have any cleaning records since it was passed on to me, I decided to have it cleaned na rin. The unit is working fine now and smells nice too!

How can I prevent this from hapenning again? Should I put the thermostat into heating position once in a while during long drives para maiwasan ang pag yeyelo?

By the way I drive a '98 Isuzu Trooper (local UBS69) and just to share my experience with this vehicle, driving was very comfortable. I tried cruising at 160kph with no sweat at all!
