My 2004 SR5 beside having the occassional sqeaking mouse sounds coming from the passenger side of the dash has a new noise. After i start it up a noise that sounds like an air pump running runs for 15 seconds. That was yesterday. Today the noise cycles on and off erratically. My friend suggested its maybe the heater control valve or core. When i elevate the temp, the noise stopped. Even after i lowered it again. Any ideas would be appreciated.
Strange noise?
