i have had the displeasure of having to replace the radiator on my v70 1998 auto,unfortuntely in the actual process i have removed all the parts including of the large condenser panel, disconnected pretty much everything there was in my way when i pulled the whole thing out. that also included the pipe work for my air conditioning system. now after a few days of struggle getting the right part in as i am in australia i put everything back together but unfortunately there is a buzzing noise when the ignition key is turned on to contact position 2.
can anyone tell me what and where this noise would be coming from and what would i need to do to fix it up( get rid off the noise).?
any help is greatly appreciated as mechanic in australia are unscrupulous and they all charge exorbitant fees just because we drive euro cars.
thanks in advance
