So when I start my car up and start driving around, within the first minute of driving my ACD pump makes this whirring noise like it's dead heading. But then it stops doing it after that. I dont have the 3 lights popping up and it seems like the pump works fine after that initial spasm. When I press the gas pedal and turn the key twice, it makes the dead head noise then it goes back to normal operation. Anyone else have this happen? I'm 99% sure I just need a new pump but it's still strange that it stops doing this after the initial time...

 

Did u check the fluid level?

 

Yup, that was the first thing I did and the levels are fine.
