Hello, I have a Volvo S70 T5 1998 and when I turn on the AC it makes a loud sound and the sound gets louder if I increase the AC slider to MAX. It also smells something like burnt rubber when I open the hood. Any Ideas? Thanks, Jim

 

Hey Jim, with those exact symptoms, I would pull off accessory drive belt and check. Could be belt slipping on the A/C clutch pulley causing noise and burnt rubber smell. Maybe assy. belt tensioner not giving enough pressure for the belt not to slip too. I take it you are getting squeeling type noises? Does it stop when a/c is off?

 

Hi jsj_297, Thanks for replying. Yes, if I turn the AC off the sound goes away. The weird thing is when it first happened I was driving home and it made the car kind of sutter so I turned off the Radio then the air and as soon as the air was turned off I was fine. I am hoping it will not cost an arm and a leg to repair. Once I got it home I popped the hood and turned the air to low and could hear an awful grinding noise but I don't know where it is coming from. So thenoise itself is more like a grinding. Too bad this site doesn't take videos as I have taken a video of it.

 

Sounds like maybe your AC Compressor is going bad. Not sure how expensive a fix it is but as with any Volvo it wont be cheap.

 

But another notch in your belt!! AC Compressor was the problem and it was expensive. Thanks for the GREAT info!!

 

'ow expensive?
