My Air-con Problems: Sometimes not cold, especially after long drive when engine gets really hot, and the air smells really bad.. Tried in 6 months with various merchants for inspection, servicing, gas top-ups, etc. but without any improvements.. Last week went to Loh Kum Seng Motor, recommended by one of my brothers as his friend is working there. The Mechanic (Ah-Meng) spent 1.5 hours to diagnose my air-con problem. Finally my misery is solved now after replacing the faulty fan! :-)) I would never have guessed the fan was faulty as it was still working. Even established merchants whom I went previously was not able to point out this problem. With Ah-Meng's experience, he is able to identify that the fan speed was too low. Great experienced professional!
