Whenever I use my heater of a/c my car makes this groaning noise. Sounds pretty bad and u can feel an almost vibration in the gas pedal. Not sure as to what it is but would like some help stopping it. Someone told me maybe a new water pump because my old one might be working to hard and making the noise. Any truth to this statement?.... Thanx for any help.
