[QUOTE="BimmerDan, post: 477448, member: 3935"] The problems with my A/C is solved. 1. A whizzing noise from the blower which correlates with the acceleration. [COLOR="red"]Its seems the compressor was completely out of oil and therefore making the whizzing sound. Had the oil put in followed by refilling the freon...problem solved.[/COLOR] 2. During long distant travel the (100kM-300KM non stop), the air seem to be just cool and not cold; even though bringing the temp. down to 16. The weirdest part is, within city driving its cold even at temp 23. Bizarre... [COLOR="red"]Although there were several possibility that could have caused the AC to behaved in such a manner. I started with the simplest diagnostic which is to check Thermostat. Turns out the Thermostat was dirty (noticeably corroded) and had it polished with (any) metal polisher and after reinstalling it back into the car the difference was instant. I am just glad it wasn't the more expensive repairs such as climate control, sensors, condenser etc [/COLOR] I hope this will help those who are currently experiencing the similar pattern with their AC.
