:help: I have an 03 dak with the heavy duty service package,which includes an electric fan. Every time the electric fan kicks on(usually when the A/C comes on) I get a bad vibration from it .You can feel it strongly in the steeringwheel and on the fan shroud. Dodge won't fix it because I had a minor front end accident in which the fan was replaced because it cracked. I checked for loose parts but found nothing. What could be causing this.It feels as if the truck has a nasty rough idle. Any info would be helpful.
