your not giving year ,but should be OBD11 unless 1996 or earlier.There is offered software that plugs into laptop with special harness, but it is pricy, recommend you get OBD11 tester from say Autozone,on sale $ 59.00 to $329.00.
Nonworking LightsSince the fuse has been replaced [and I hope the new fuse is "good," and has not "blown], that suggests the cause is an "open circuit" condition. Usually, open circuit conditions are caused most commonly by:A wiring harness connector has become "unplugged," orCorrosion has built up on the metallic connector pins INSIDE a connector or any type of connection,A conductor [wire] has been broken or cut.There are probably a few more possible causes which I can't recall, but these are the most common.

i have the same problem on my cobalt ss 05 and i cant find the anwser
Try unpluging the Ignition control module while the key is in the on position. Wait until you here the relays click, then plug it back in, next do not shut the hood or door, try starting it. If it starts, then you either have a bad Ignition module, bad harness connector or a sticking relay. This is the problem I have on my 94, but it happens more when it is hot. I discvered this while searching the internet for my prolem. I saw this for both hot and cold conditions. It is call the famous Ford connector wiggle test. Good luck. If you find it to be something else, please respond back to this post as I have still to this day not figured out what the exact problem is. Still wiggling connector Run1

The diagnostic connector is along the wiring harness, under the hood, on the passenger side firewall.The diagnostic connector is along the wiring harness, under the hood, on the passenger side firewall.
Open the hood and look at the firewall area at the left rear of the engine compartment. There should be a large multi pin connector and a single pin connector hanging from the wiring harness near the a/c drier.
A 1991 Dakota is not OBD2 compliant. It is OBD1, and the diagnostic connector is under the hood on the wiring harness on the passenger side firewall.A 1991 Dakota is not OBD2 compliant. It is OBD1, and the diagnostic connector is under the hood on the wiring harness on the passenger side firewall.
diagnostic connecter 1995 dodge truckThe diagnostic trouble codes on all models can be extracted from the Powertrain Control Module (PCM) using the (OBD-1) scan tool. The connector is along the wiring harness under the hood, on the firewall on the passenger side.
The blower motor resistor is above the passenger side close-out panel, below the glove compartment and towards the firewall. There will be a wiring harness leading from it to the blower motor and another harness leading into it. The harness leading into it will have a 4-wire connector and the harness leading to the blower motor will have a 2-wire connector.
front left side of engine compartment, near the exaust.
The diagnostic connector is under the hood. It is located along the engine wiring harness.
It's located on the firewall inside the engine compartment, just below the the wipers. A bolt in the center of the conector holds the connector/harness into the computer.

Disconnect the fan motor electrical connector. Unbolt the fan bracket and shroud assembly. Take the harness connector from the shroud. Lift the shroud out of the engine compartment. To separate the fan from the motor take loose the motor shaft clip. Remove the bracket from the fan motor by detatching the harness from the retainers then remove the mounting screws.
follow the wiring harness towards the pass. side of the engine compartment from the distributor,it only leads to one thing!!! If you have an A/C equipped model like I do, the SPOUT connector is right up against the evaporator housing on the engine side, hanging out of a wire harness. It's a black connector shell with 2 short yellow/green wires on one end, and a removable plug on the other. It's taped to the side of the harness, but not wrapped in it.
The knock sensor sub-harness connector is located on the passenger side of the engine compartment next to the intake manifold. Must be checked by observing voltage fluctuations with a voltmeter.
