Help! We have had several electrical type issues (I am NOT a car genius) with our '05 Grand Cherokee: ABS light, airbag light, etc, etc coming on and off at random times. Now, when I turn the ignition I get a crazy noise, every alert light comes on and the vent is blowing at FULL speed (but not set on 'high'). It takes 2 to 3 times before I can get it to turn over. THOUGHTS???
