    My AC only blows low speed or high speed. All intermediate speeds seem to default to the low fan speed. Has anyone else had this problem?

    This problem is on a 1999 360 modena euro spec.

    When fan speed is put in auto mode, and temp is anything except the low temp setting, the AC blows low speed only.
    When fan speed is put in auto mode, and temp is on 'low', the AC blows high speed only.

    When manually adjusting the fan speed, all settings except 'high' blow the AC at the low fan speed only.
    When manually adjusting fan speed to the high position, AC blows 'high'.

    I would like the regain these intermediate settings again. The high setting is too loud and unnecessary. And the Low setting isn't sufficient for Texas heat!

    Any help would be appreciated.

    It should have a blower motor resistor, when they go bad low speeds wont work correctly. Call the dealer and ask for one. Also ask for the parts diagram so you can locate it and change it.

    Good luck,
