My wife just pulled into the drive about 10 minutes ago and shut down,but the car has some sort of running pump noise coming from the engine compartment. I pulled the engine cover off to try and find the origin of the noise. I thought it had to be the secondary air pump but when I put my hand on it there was no vibration felt. The noise sounds like it is coming from under the A/C pump,but of course that was not running. I'm at a loss, are there other electric run pumps under there?
