[alexsr20]

excuse me,y everytime if my a.cond is on while my car is running it wont be running smoothly?it's like the car was pulled n pushed..can someone tell me the reason pls....im a newbie here..thx!!

it is normal... coz the aircond compressor gets its power via pulley from ur engine... thus, extracting power from ur engine to run it....

but if u say the problem deteriorates over time, i not too sure about this... i'm facing similar problem... there is a huge difference when aircond is on and off... its like 30% power gone...

Check the compressor. Either the bearings are worn or the belt tension is too tight...
If you start feeling the same even when the A/C is off, the the clutch assembly for the A/C might have gone kaput!
