There ought to be an in-line filter strapped inside the driver side frame rail, just in back of the transfer case, it looks like a metal can with hose fittings on the ends.. The resistor you mention is what gives the different speeds for the blower motor. Are you using a Chrysler DRB or a generic OBD1 scan tool? If you have a working DRB II scan tool. you are indeed a fortunate Dakota owner. Do you have the instructions for whatever you're using? Typically, there is a KOEO (key on engine off) and KOER (key on engine running) code retrieval mode as well as a real time scan mode. I really can't tell you how to operate the particular instrument you have, you'll need to refer to the instructions. I can say, from my experience, that an Innova Model 3140 OBD1/OBD2 tool works just fine on my '93. I am not a huge fan of Auto X-Ray, I wouldn't buy another one in this lifetime.
A FSM is a Factory Service Manual, they are worth the money. One can be found on ebay.

I have the innova 3140 tool and both of the FSM Vol 1 and 2 . I used it in koeo and koer and in the real time modes, no codes have been set. I'll be pulling the bed back off tomorrow and pulling the entire module out to test and check I ll post upo what I find. Thanks againGary

OK, I don't claim to be knowledgeable about every year of Dakota. It is possible other araingements were made on your model, or someone may have deleted the filter. That doesn't sound like a good idea, could lead to clogged injectors or regulator. Since you have the FSM, volumes 1 & 2, you tell me where it might be located on your year truck.
I am left scratching my head on the scan tool deal, you should see various info such as O2 sensor voltage, RPM, MAP and etc. in real time. If the PCM isn't communicating with the scan tool, it suggests an issue with the PCM to me.
Codes aren't generated by many fuel issues (unless you have a failed injector). I dropped my tank. Here in the rust belt, the bed mounting bolts are problematic (hell, everything is problematic). Be careful with the hose going to the roll over valve, if you break the barb off, you'll be crying.
