I have just returned from 3 weeks away and 2007 (57) plate Audi Q7 fan blower is not working. Can hear slight tapping noise behind dash although when i lift bonnet you cannot hear anything. Is it that battery may not be fully charged and Power Management Unit is not providing enough electric to power heater / air con blower ?

Heater working fine, left standing for two weeks and found no blowers working when I started engine up Any ideas?

Appreciate any help....

Hey WESTERN803,

It sounds like it can be one of two things, either the blower fan has gone out or the blower fan control module is bad here is a wring diagram and a test guide to help you get the problem fixed.
