hey i just noticed it makes that fast ticking noise when youre outside the car and the ac is turned on. i can mostly here it when the fan is running also. is this normal?? anyone hearing this too??? ...but its quiet when its off. i assume it is normal.

 

its just the compressor turning on and running.. no big deal unless it is a loud out noise that is probibly out of the ordianary

 

Mine does the samething wen the A/C is on but it seems to be comming from the MAF. The only answer I've gotten was if theres no CEL don't worry about it.
...tho in my 15 years of automobile ownership sounds like this are never supposed to be this loud.
