Have noticed a few noises and wonder if these are anything to seriously be concerned about.

1. Have noticed when I touch the accelerator especially when only going 30 MPH or so I can hear one click as my foot applies pressure, this only happens when just touching it with my foot, after applying more presure no noise at all. Its pretty random and dont happen everytime.

2. My air con is first class and cabin is cold within a minute or so after switching on air con even in hot weather. But when air con is on can hear a distant humming, its not all the time just seems random, also when swtiching car off can hear sort of a hissing release sound for about 30 seconds. These noises are not there if air con is off so its certainly air con related.

Have been told its nothing to worry about as ford air con is know to make a few noises like this but just wanted to check here.
