Hey everyone! new to this board. Would be great of anyone can help me out with a small issue. I have a 96' Mercedes c220 that I purchased from a previous owner. Everything was great until I turned on the air conditioner. The car started to jerk a bit and I smelt rubber burning. Might have been due to a belt loosing traction from a/c area of motor. not really sure what part could be malfunctioning. This only happens when I turn a/c on. Any tips or hints would be appreciated!

 

The clutch could be bad on the AC compressor

 

Thanks for the reply. could it also be the round pulleys that might be defetive?

 

When you turn on the air conditioner that is sending a message to the ac to engage the clutch, I would have someone turn on the ac and you can watch it under the hood..
