Hi.. recently my mechanic said my aircond wind not powerful enough but to me I dont find it any problem as during hot afternoon I full blast and even medium speed the aircond is cold and able to keep the temperature cool day n night. He advise me to service the aircond to clean the coil but he needs to remove the dashboard to service. 6years persona without servicing aircond before. I am just worried is there a need to remove dashboard to service aircond or should I touch the aircond system at the first place since all working fine and cold. Btw he is charging me 300+ for cleaning to make the blower faster..hmmm
