The heat/ac was a long time in failing, 6 months at least before it stopped completely. It was an intermittent thing even when you could get it to come on whether you were on heat mode or cool mode. At the end it would cycle on and off even while you were driving. The button controls on the dash for fan speed, temp adjustment, and air high/low position all seem to work just fine., at least that is what the digital read out is indicating. How might I test the blower with out hurting some other circuitry. Also, what and where is the control module? for this car??

Sorry I don't know where these items are located. However, I do know that your heater control can be checked for proper operation with a computer just like the engine can be checked.
