i driving BT 20v. not sure about urs.facing same problem last time. turned on can heard aircond fan running. after a while, led started blinking, fan stopped. found out fuse burned. the fuse is located just right under the glove box at the passenger side.(better check this one before you start changing other things)
after changed, no more blinking. thought yeah, finally can go out toasting
. but found out how come fan totally not spinning now. no choice lo, need to look for aircond sifu. lastly checked and found out sensor kong(if you open up, it has 4 kaki). i'm not really sure this thing call sensor or what. could be some members here called it "aircond ecu". i will snap pic tomorrow so you know which one i mentioned. make sure you replace it with DENSO and NO NO NO other imitations. before that, i kena already because i replaced it with imitations since the taukeh told me denso out of stocks. FYI, once this sensor has been taken out, you need to pump in new gas. yes! yes! yes! aircond is working now.. but u know what has happened next? the fan keep on spinning non stop. ask the taukeh why like that, he also not sure and told me wiring issue. i told him cannot be what. checked many times here and there but still couldnt rectify the problem
no choice lo. need to go back already because got other things to do. next day, dont want go back there already. i just brought my car to denso dealer and told the expert what i did and replaced. straight away he told me, if those sensor has 4 kaki means it has extra functions. usually other car sensor has 3 kaki. this sensor has extra function to control the aircond fan 2-way speed, slow and fast. no choice but need to replace again and pump in new gas which cost me more(hard earn money ma, of cos boh syok lo). but luckily ori denso sensor cost me 60 bucks. after that, all fixed.....at nite sleeping also can smile :proud:.
yes, if you found out the fuse keep on burn after it has been replaced, it might be your compressor causing it because running overload. hope it helps.
