Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

1998 Dodge Ram Van 1500 Owner Comments

problem #1

Ram Van 1500 B1500 5.2L

  • Automatic transmission
  • 79,100 miles


I need help with current issue with my 1998 Dodge B1500 VAN.

1. When AC is selected, air ONLY blows out of the top vents when the temperature knob is in the hot position BEFORE the AC is selected.

A. If I move the temperature knob from hot to cold or leave in the hot position WHILE the AC is operating, then GOOD air flow from the top vents

B. If I move the temperature knob from hot to the cold position BEFORE the AC is selected, then NO air flow from the top vents but can hear the blower.

NOTE: I removed the glove box and when the HVAC control knob is moved to floor, defrost or any position, the bottom right door baffle opens and closes accordingly and air flow is cold or hot depending on the temperature selected except as mentioned in 1B above. When observing, the top arm of the Actuator opens and closes the baffle door depending on what option is selected. Therefore, in my opinion, the Actuator is operating correctly unless one of the electric pins in the Actuator controls temperature?

Your comments and input are welcome and appreciated to resolve. Thank you.
