What owners report

The ventilation system failed as is common with these vehicles. Due to weal parts, the, "doors" that control air flow through the ventilation ducts broke. I have slowly replace each of the four doors as they failed. As they went out it affected every aspect of ventilation, including the defrost. After doing some research it is evident Dodge was fully aware of this issue but made no improvements to the system, continuing to sell these vehicles to an unsuspecting public for several years.

1998 Ram · Appliance › Air conditioner · Aug 1998

Air conditioning vent always switches to the defroster and back to the ac vent. While driving in the snow and ice the heater was on, the defroster vent automatically switches to the vent on the floor and the ac vent causing the windshield to ice up causing no visibility through the window. Did run off the road. It's been doing this ever since that day. Nothing has been done because of the expense that the garage attendant said. Have dealt with this for along time. Truck is in very good condition. Sharp!! The reason I am reporting this time is that I nearly escaped from hitting a tree this last ice storm. Don't want to be a statistic.
