We have a 2001 Dakota Quad Cab and it has started allowing air to come through the air vents when the truck is moving. Although the fan switch is set to off, air still flows through the vents as the truck is traveling. I believe the recirculation door is a fault but I don't know how to access the door. I can hear the door flap open and close everytime we open and close the trucks doors. Called the local dealer and the qoute for repairing the door was 800. Don't have the money and believe I could fix it myself if I knew how to access the door. Any help in how to access the recirculation door would be great

dodge dakota climate control lights by simonds

just bought a 97 dakota 3.9 L. The issue is strange to me, when i open the door or set the remote lock, the lights on the climate control knobs come on instead of the dome light. I am also in the middle of troubleshooting the blower motor, the moter is fine (jumped from battery) so the issue is in the climate control knobs or the resistor block. didn't know if the lighting issue and the blower moter not getting power were related?

You will have to remove the Heater Housing. Not a simple or easy job.

You didn't state what the problem/symptom was with the blower motor, however, if the issue is one or more of the fan speed positions (usually the high position) is not working, the Blower Motor Resistor is probably the culprit.
 
Don't have any suggestions regarding the lights, however one thing that is common to both is the Central Timer Module.
 
Best regards,
Dusty

I live in Saskatchewan at present it is -40, The heater on my 2003 Dodge Dakata QUIT working which is expected in this cold weather, I took it apart and checked all fuses, there all working, I then pulled the plastic shroud off, and unplugged the wiringplugin to the main blower switch, and test lighted it and found there is no power at the main wire or anywhere in the blower plugin switch. Is there any other places to confirm power source, .................Lorne

Is the AC/Heater blower motor operating?

My apologies, but I'm having some nomenclature problems with your symptom description, so I'm going to be very detailed in my response.
 
With respect to vehicle ground (frame & body), which is negative, power is delivered to the Heater Blower Motor at pin 1. DC power gets to the A/C-Heater Control Switches via the Blower Motor Resistor at pin 2. The circuit is as follows:
 
1. Fuse #13 (40 ampere) in the Power Distribution Center (PDC) located under the hood next to the battery
 
GOES TO
 
2. Ignition Switch pin 1, then comes out pin 2 (run position)
 
GOES TO
 
3. Heater Blower Motor pin 1. DC power goes through the motor at pin 2.
 
GOES TO
 
4. Blower Motor Resistor Block at pin 2 (DC in). The resistor is located next to the Heater Blower Motor. The black blower motor wires will go to it. DC power goes through the three (3) resistors (pins 3, 4, & 5), plus passes through without resistance at pin 1 of the resistor block.
 
GOES TO
 
5. The A/C-Heater Control Switch
 
Pin 1 resistor block - to - pin 10 of the heater control switch (high position)
 
Pin 3 resistor block - to - pin 3 of the heater control switch (not so high position)
 
Pin 4 resistor block - to - pin 7 heater control switch (medium position)
 
Pin 5 resistor block - to - pin 2 heater control switch (low position)
 
Pin 8 of the Heater Control Switch is 12 VDC for the panel illumination lamps.
 
Pin 5 of the Heater Control Switch goes to ground.
 
The most common cause of blower failure on Dakotas of your vintage is the resistor block, a very common problem. I would recommend removing the resistor block, which is mounted to AC/Heater box next to the blower by two screws. I suspect you will observe signs of pins and wires overheating at the connector. This will need to be repaired. The resistor is part number 5174618-AA and a connector repair kit is (was) 5017124-AA. If the resistor displays signs of overheating, you'll probably need both.
 
Stay warm up there in Alaska!
 
Best regards,
Dusty
