SOUNDS LIKE YOU ARE LOW ON FREEON YOUR SYSTEM NEEDS A CERTAIN AMOUNT OF PRESSURE TO TURN ON AND OFF SO THE FAN TURNS ON WHICH IS NORMAL BUT THE CLUTCH ON THE A/C COMPRESSOR IS NOT TURNING ON 1/2 -1 POUND NEEDS TO BE ADDED TO YOUR SYSTEM

    IF IT STARTED TO SMOKE YOU WILL NEED TO ADD OIL TO THE PUMP ALSO ALONG WITH FREEON OIL FIRST THEN FREEON

My 01 cougar makes a noise like a pump is going out or is clogged could someone told me it sounds like the ac, but it does it even when the ac is off your thoughts


there are several items running that can produce a noise
the water pump bearing will be a grumble or a tinny rattle , the idler pulleys will be a rattle, the ac pulley is on a bearing separate to the ac operation and is running all the time and the problem noise could be from that bearing
the alternator bearing will make a medium pitch rumble and if you have a viscous ( clutch hub) fan hub the bearings in it will produce a noise
an accredited mechanical shop will have a stethoscope and a good mechanic will be able to determine exactly where the noise is coming from

When the ac is on making a rattling noise...doesn't do it when it's off


Could be a bad bearing in the blower motor or the fan itself loose on the shaft of the motor.

Ac not working and makes a rattling noise


Clutch fans make noise when low on R-135A...If you have not tried yet, follow can instructions and add a can of R-135A...the can instructions are very helpful...If you have already tried adding a can, a leak is apparent, and needs a quality mechanic look...Hope this helps.

HVAC is making rattling noise


Your fan that is attached to your blowermotor is loose, causing the rattle, or the bearings in your blower motor are bad, causing the shaft and fan both to rattle.

Best possible solution for clicking noise while fan is on MC 2005? Even if you turn off AC and leave fan running you get the noise. It stops only if you turn off fan completely... Thanks!


This is usually caused by ethier the fan is touching the side of the housing, or There is something stuck in the fan housing. Items can fall down the vents easily Becoming trapped. Paper is great for making clicking noises, my customers complain About clicking or a rattle like sound I usually find a small piece of cardboard or paper In the fan or duct work. Ethier way you will probably have to remove the fan, or access The duct work in some fashion to find the cause of your noise.:-)

When ac compressor engauges you can notice strain on engine . Shortly after that a line came off condenser with a loud bang.The line that broke goes from compressor to condensor. Now compressor is noisy....


The head pressure got too high on the ac system,when you have the ac compressor replaced,and it`s components,make sure the condenser is flushed out good,and that the cooling fans are working with the ac,they need to come on with the ac,if this was at all helpful,please rate,thank you.

The fan makes a lot of noise


this could be normal operation of viscus fan hub, it is engauged when you 1st start up when cold then a minute or two out of drive way when taking off they cut out
when idling it should cut in and out also
