I have a 2005 Chrysler T&C with 29,000 miles. The Malfunction light came on today. Any idea what the problem could be. It did not blick just a steady light. The vehicle seemed to run fine.

The "Malfunction" light came on indicating the Power Control Module PCM has detected a fault in an engine or transmission sensor or signal. Since you're still under warranty take it to the dealer. They will connect a scanner, read the fault code, and fix it for you.
