Question about 2002 Dodge Ram 3500 Truck

1 Answer

1995 Dodge diesel. Heater fan runs but no air flow. Vacuum okay

Checked vacuum at mode switch = 20 inches. Pump supplies to 25 inches vacuum.Tried using a portable vacuum pump that goes to 26 inches vacuum but still no air flow. Recirc damper opens okay. Fan runs okay. No air flow comes from any port; floor, panel, defrost. I even tried vacuum at the mode vacuum hoses; still nothing. How can I get at defrost actuator without removing heater system from cab?

Two actuators can be accessed (enough to move them) without removing it. One is on the bottom of the HVAC unit on top of the trands hump, you will probably have to remove the airbag module and cover to get to it. The other one is on the driver's side of the HVAC unit about half way up. Remove the driver's side knee bolster and you should be able to see it.

1991 dodge dakota heater vacuum air flow shutters son't move


Taking your heating box apart may be a really big job.
It would be good to check the vacuum supply at the heater box, and/or at the controls.
Lack of sufficient vacuum can cause the heater to not work.
The low vacuum could be due to a vacuum leak somewhere before it gets to the controls or the heater box.
Then, the heater box or flaps could be stuck or warped, causing malfunction.
It is all repairable, but can cost you a lot of time and effort fixing this.
God bless your efforts.

2003 f250superduty,4wd will engage if hubs are locked in will not engage when hubs are set to auto


Most common problem is a vacuum leak to the hubs. Check the lines from the vacuum pulsating solenoid all the way down to each hub connection. If the lines are good,use a vacuum pump to apply vacuum to the hub with the line removed. You should hear a slight click at about 5 inches of vacuum if the hub seals are good(test both hubs individually). Just one bad seal in either hub can cause the entire system to malfunction.

New fuel pump, ccrm and fuel filter and still blowing 20 amp fuel pump fuse


If the components are all good, then check wiring connectors and wiring circuits, it appears the problem is after the ccrm. wiring from ccrm to fuel pump. For testing you should be able to use jumper wire with inline 20 amp fuse, from voltage to fuel pump connector, to see if it will run w/o blowing the fuse. As you can see from ccrm to inertia switch there are two connectors. From inertia switch to fuel pump, one connector. There are many ways to test. With connectors unplugged, you could use a test lite connected to battery voltage, touch correct wire terminal, if lite comes on, that circuit is going to ground, somewhere.
See that one wire that goes down, wire circuit from ccrm to inertia switch, that wire goes to pcm, I believe it to a monitor circuit, the pcm monitors the voltage on that circuit.

1990 Dodge Caravan A/C / Heater blower fan mode control won't work


The mode doors are operated by vacuum. Check the vacuum supply line to verify it is connected to the intake manifold. If that looks good, remove the control panel to see if vacuum is coming to the mode switch. Then check to see if the switch is transferring vacuum to the actuator lines. Here is the panel removal procedure:
  1. Disconnect the negative battery cable.
  2. Remove the necessary bezel(s) in order to gain access to the control head.
  3. Remove the screws that fasten the control head to the instrument panel.
  4. Pull the unit out to troubleshoot.
