Chrysler Repair: 2004 Town & country touring 3.8L, automatic temperature control, c works

Question
Can't figure this one out but may van's a/c works, but the fans that push the air out the front vents intermittently works. It's wired, but sometime it work then other time there is bearly a trickle comeing out the vents. They seem to come on when turning left??? The rear fans work very well and freeze our kids out while we bake. Any Ideas?

Answer
Hi Jeremiah,
Have you checked to be sure the blower is not slowing done but instead the air is being diverted to the windshield or the outlets under the dash? Does the blower speed audibly decrease when this happens? Is this a conventional or and automatic temperature control type of system?

PS Sorry for the delay but I just found your question in the 'pool' to which it had been referred by the other expert.
