On my 02 dakota i replaced the ac/ module in steering colum an a month later the air wont work but on high.
Is the blower motor whats poping this ?
I see this is a very common problem in dakotas.
Last one i had ,it kept poping resistor over an over.
This one i havent had to till now,after module replaced .
What should i look at or test when replacing resistor ?
Is blower motor usually the culprit?

I see online they are drawing too high amps .
What amps should it draw? ,
Is there a blower motor off a different dodge that i can wire in where other is an maybe not overload the circuit,with lower draw?

 

If there are leaves stuck in the fan, your motor has almost no resistance (until it's spinning). I have a 2000 dakota and my resistor is hard to access but if you get in there, you can get a lot of stuff out with a vacuum. Look for access ports to the heat/ac manifold and see if the motor might be dry.

 

The connectors from the resistor to the wiring harness tend to be too loose. I solved my continued burned out connectors by hard wiring straight to the harness.

 

Would using the fat gteen wires with the replacement resistor solve that issue?
On my other dodge i no longer have the last owner had that new wiring harness an it still burnt on 1 circuit. Now that pne wouldnt work on even high....On the resistor plug inside there was a burn mark .
This one works on high.

 

Got it working again

The air doesnt flow evenly out vents in middle though..
Is there a piece i need to reattach for front middle vents?

 

I blower Fan Motor typically draws around 1.5 amps on high with no load. When the motor gets stuck it acts as a short circuit and can draw enough amps to melt the wiring. .By putting a in-line fuse when you do change the motor out it'll save the resistor and the wiring from burning up next time the motor goes out.
