One problem related to defogger has been reported for the 2003 Chrysler Town & Country. The most recently reported issues are listed below.
On 2003 Chrysler town and country lxi I had to replace the blower motor relay last year. Now the mode door actuator seems to have failed! I can not change the air blowing through the dash vents to defrost. This is the second time this Chrysler model has had defroster problems! two separate parts failed, one this year and one (blower motor) last year. This seems to be a common problem with Chrysler vans and no recall? for not having defrosters?.
