On certain pickup trucks, the electrical connector at the bottom of the steering column contains an under-sized terminal for the HVAC blower motor circuit. Localized heating from current flow with the blower speed set on high may cause the terminal contacts to relax and lose electrical contact. This can cause the HVAC blower motor to become inoperative.
Dealers will install a wiring harness overlay to correct this condition. Owner notification began April 15, 2003. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact DaimlerChrysler at 1-800-853-1403.
