    Furnace fan make noise when starting only during heating
    My furnace fan makes a struggling noise when on heating mode only.
    It sounds like the fan has a hard time starting.
    When on air conditioning mode it doesn’t make that noise; the fan sounds fine.

Noise when starting Honda Civic 2003 [ 1 Answers ]

My 2003 Honda Civic makes a spinning noise when it starts. It sounds like it is coming from the front left. Eventually it goes away as I drive. If I put the breaks on, the noise goes away but resumes as soon as the breaks are let off. It is more likely to happen if I start the car and back out...
