noisy climate control
Hi there,I have a 4.4 patrol D3,and I have a problem when the climate control is on, , it makes a noice when you drive. at low range you hear it more. When you turn off the climate control, you no longer hear it.
Can you help me please? Thank you!

What type of noise, inside the cabin or under the bonnet
Under the bonnet it could be just a Aux Drive belt worn, or a AirCon pump bearing. Try spraying WD40 on the pully bearing.
Inside it could be a noisy fan, but not heard of this before........................but a known issue can only be described as a FART, the aircon has been known to do this.
Do a search on this, been discussed before, many times

When I'm accelerating the sound mimic the sound of the acceleration, and I think is from the bonnet. And where I can find the pully bearing. Thank you

Where theres belts there's pullys to provide friction and traction. Could be any of these. I would suggest a squirt of WD40 on ALL of them in turn, one at a time to see if the noise goes.
But to be honest this is just chasing a possible fault, maybe a trip to dealers for piece of mind

Mine was exactly the same .. took it to a dealer and they diagnosed the belt tensioner pulley bearing but when they took that off and replaced it the noise remained - turned out to be the pulley on the end of the A/C pump at fault so they had to replace the whole pump apparently.

Sounds the same as my Air Con pump bearing failure. whines with the engine revs & progressively got louder & louder over a period of time.
WD40 is good for freeing potentially stuck or sticking bearings, but not that good for rubber belts..... Bodsys Brake Bible
