    When I turn my air conditioner on, the dashboard starts to make a violent vibrating noise. It stops when I turn the air conditioner off.

    The AC is blowing cold air, so what could the problem be? :dunno:

    Loose evaporator coil, vibrating from the force of the compressor pump in the engine bay. That's my guess.

    Would that being loose make the vibrating noise loud?

    It is pretty loud; you can turn the radio all the way up and still barely be able to hear it over the rattling.

    I'm fairy ignorant when it comes to the Civic's AC system, so I have no idea. :o

    what happens when you turn just the fan on, or the heater?

    If I just turn the fan on with no AC, it still makes the noise.

    I haven't tried the heater, though.

    Aw goddamnit, I thought he'd already tried that, hence why he specified "when the AC is on".

    If it makes that noise whenever the fan is on, then the fan is fucking broken and it's rattling like crazy because it's off-balance. Replace the fan.

    By "the fan being on," you mean you can slide the fan switch over (from 1-4), but make sure the AC button isn't pressed in?

    If so, yes, when I do that I still hear the noise.

    Mine seems to be just as loud regardless where I set the AC.

    My dad thinks it's the blower, but I guess we'll just have to get under the hood and see.

    Did you fix it yourself? If so, was it a pain in the ass?

    Always be sure to check EVERYTHING. I kind of figure people asking questions about rattling in their car don't check everything first ;)

    I put my hand on it when the car/fan is running, and it is definitely vibrating. That's where the noise seems to be coming from, also.

    I think you speak truth. :bigthumb:

    I looked under there last night ans it seems to be where the noise/vibration is coming from.

    I took a few pics:

    It looks like you just undo those bolts/screws and the blower motor should be on the other side of that plastic piece?

    Replaced it last night, and it was pretty simple.

    I had to cut the connecting wires because of the way the replacement part was made, but everything fit perfect.

    Running nice and quiet today. :)


    Thanks for the help. :wavey: :bigthumb:
