The cooling fan starts within 10 seconds of turning on the ignition (even after sitting all night - engine obviously not hot) and runs continously and loudly. People have said that it sounds like a jet engine. New a/c was recently installed by volvo mech. took to private mech. and they thought it was fan motor & control module. They ordered new and replaced. Just spoke with them - that wasn't the problem -still turning on immediately and loud. They put the old fan motor back in and are now troubleshooting for a cause. Any suggestions, information, solution would be appreciated.
Thanks much.
