    I have a problem with my ventilation of heating.

    Hello,
    I have my ventilation which does not work in 1,2,3 speed.
    She works that on the last speed.
    I already have to change:
    -Engine of ventilation
    - The button of command of ventilation
    - Blower motor relay

    That works always not ?
    The complete block of command which raises problem?

    Excuse me for my English

    Re: I have a problem with my ventilation of heating.

    So im hoping just to jump on this thread and not create a new one. I have an 06, and the blower stopped working this morning. It is an automatic one with dual climate control. I tried turning on the defrost and manually cranking it, nothing seemed to work.

    The blower control module is bad(its next to the blower on the bottom of the dash)

    There is a brain module that works everything for the front hvac unit including the blower control module

    Junkyards are cheap(if you want to)
    Rippy on here is another good source
    Any gm dealer can get it
    Gmpartsdirect is a good site
    Rockauto is another good site
    eBay would be another(if you trusted the sellers)

    That's what I'm thinking. I've replaced a couple the blower resistors over the years and them failing always caused me to lose the lower (sometimes all) fan speeds. They aren't cheap but if you have access to a salvage yard then you might score a deal.

    I had to replace the blower resistor in my 98 Oldsmobile last summer. $250+ from a dealer, almost $200 from a parts store, and $6 from the salvage yard near me. I fixed it in the yard's parking lot so I could have my A/C back and enjoy a cool ride home.
