I have an odd issue that started happening when my car was accidentally towed.

I hear a faint rattling on the drivers side whenever the AC or the Heater is on. The noise will be there when the engine is idling and I am pressing the brake pedal or when it goes from 1000-2000RPM's... It seems like there is something loose in the engine bay but I have no way of finding out what it is.

If I park the car, it will not make the noise, I have to have the car in drive and the break pedal pressed down. The noise gets louder when the engine is running hot.

Any help would be greatly appeciated.

Thanks,
David
