93 325I AC Problem

[wz2wj1]

My ac pump is cycling off and on but very quickly . The car is getting cool but not cold. Then the pump is making a vibration noise when it comes on especially at lower speeds. ANy ideas or things to check? Or is it the pump going bad?

thanks

If your AC cycling on and off check your AC pressure. check The high and low pressure temp at 80 degrees, high should be 210-240/ low 50-70. I also had vibration noise at low speeds I replace The AC tensioner and tensioner pulley, $62.00 big ones, I also notice that my AC belt was worn. AC belt $29.00 all parts from the dealer and it took me one hour to install all parts.

I purchased an ac pressure gage and my low side was too high relieved some of the pressure and it seems to be working fine. And is getting cold. Thanks for the help
