Replaced ac fan motor 4 months ago worked fine. Started to get fishy smell through ac vents then ac blower motor worked intermittently then stopped working all in 1 day. Cannot find blown fuse. But maybe relay module because engine fan motor kept running after engine off and drained battery. Seems related?
