Assalam-o-Alaikum fellows,
My car is giving me some air-con related problem that I am unable to trace it from past 2 months. The problem is that whenever I turn on the air-con in stationary position for like 15~20 minutes, the car tends to heat-up and cooling is almost finished otherwise there is no problem while on long journey, no heat-up and chill Air-con. The fan is automatic and thermostat valve is intact. My car is under-warranty so went to 3S Dealer, he said everything is good, no tension because it was working good there and he also said that there is no warranty for electrical and air-con system. Anyways I went to my trusted air-con technician, he also said that it is fine, nothing to worry about. The freon and all system is working properly according to it's ability. Now the problem still persists. Went many times to different air-con technicians, everyone of them said it's fine. I got another clue of the problem that maybe the relay went bad, checked the relay, was fine but still changed it with original Denso and kept the old one. Voila! The problem disappeared, chill cooling and no heat-up issue (in stationary position) for 3~5 days but again it started the problem as mentioned above. The problem also starts when air-con is on when I re-fuel my car or park it for just 5~10 minutes and start it again and turn on the air-con, it doesn't starts. However, the fan kicks in and the rpm rises accordingly but the air-con clutch doesn't turn on. After revving the engine for like 5~10 minutes, the clutch starts and air-con starts to cool.
What can be the major clue or problem that is hiding from my eyes? I need help from my fellows regarding this please.
