Vibrating sound when driving and A/C is on..

[finchy18]

When your driving your car and when the aircon automatic A/c switch to on you can hear vibrating sound whenver you press the gas pedal more the vibrating sound you are feeling.

something wrong or a maintenance would be replace with my aircon parts? my aircon still works good and very cool..
its just the vibration that bothers me..
pls help.. Car is corolla Xe 96 carb

bai -- i dont know if this is relevant to your query but here goes. i used to drive a box type corona (yep the 90s macho machine model but it was 4 door model lang) and it had a bad bad vibration problem that always happens whenever the aircon was turned on. there was no problem with the aircon though as it was still cold

it turned out that kulang sa support or dampeners ang area around the compressor. i never got to fix it though and just sold the car

basig mao ni ang problema nimo?

[finchy18]

thanx ha sa fast reply..

could be your a/c belt is just loose.

[finchy18]

yong nasa labas ng timing belt? diba dalawa yung makikita mo sa belts aside from the timing belt.. baka loose na nga kasi matagal na to eh di pa na replace....

[afrasay]

No, no the ac belt. yun nakakabit sa aircon compressor.

[finchy18]

which belt bro? where exactly? magkano ba ang belt? madali lng ba to mag pa replace?

[afrasay]

yun belt sa compressor which extends to a idler pulley then into the the engine pulley. Basta check mo kung maluwag. Bumababa ba ang RPM mo pag on ang ac?

[finchy18]

hindi nman bumaba.. normal nman.. ma ingay lng pero hinda masayado.. sometimes lng maingay kpag full a/c ako.. pag automatic a/c sya tumotunog..

[afrasay]

could be the idler pulley or the the compressor's bearing.
