My check engine light is on- Go
here for OBD1 Pre. 1996 to check your codes. If you need help with a code, please
post the code, don't just say, "the code said something about ______"
The 1996 Dakotas are fully OBDII compatible, Go here

Fuel gauge doesn't work- A common problem in these trucks are gas gauges that don't work quite right. (This problem is common to not just the Dakota, but also the Rams, and many other Dodge vehicles) Some people have had luck with running fuel system cleaner (such as "Chevron Techron" or "STP Fuel Injector/Carburetor Cleaner"), that might at least help the issue. While doing other fuel tank maintenance,
erock92kota discovered that the tabs the unit rode up and down on were messed up, he simply snapped them back in place, and his gauge works again.
Unfortunatly, at some point, they integrated the fuel sending unit with the fuel pump, so not all years have a seperatly serviceable sending unit.
Truck will not start- A common problem in the trucks, primarly ones made between 1993 thru 1995, was failure (corrosion) of the splice that feeds battery power to the automatic shutdown (ASD) and fuel pump relays. If these relays do not get battery power, your truck will not be able to start. This could also cause intermittent problems, orcould possibly"kill" the truck when driving down theroad.The splice is located underneath the Power Distribution Center (PDC), which is the black box located behind the battery. (See pictures below for
approximate locations)
Daytime Running Lights (DRLs), how do I disable?- Simple, disconnect the electrical connector from the DRL module. The module is located on the passenger-side inner fender (engine compartment) near the firewall. You should probably cover both ends (on the unit and on the connector) with tape.
My dash lights do not work, but they illuminate my radio and heater controls- The connector on the back of the instrument panel is not making good contact. You need to remove the instrument panel and make sure the connectors are clean. Also, you should probably add some di-electric grease to the contact. Visit
this post to read more.
My truck idles odd, or does not idle at all- It could be an Idle Air Control (IAC) motor problem. This is mounted on the back of the throttle body. It has a pintle that moves in and out (to control air flow to the engine when the engine is idling). You can take it off and clean it up and see if that helps.
My heater blower doesn't work on all the settings- Chances are that the blower resistor block is faulty. The resistor block is located on the passenger side firewall. (See picture below for location). It's very easy to change out.
How do I check my automatic transmission fluid level?- Start engine and bring it to operating temperature (usually done by driving a few miles). With engine at operating temperature, park on a level surface. Shift the transmission through all the gears, and shift into neutral. Set the parking brake and pop the hood. Check transmission fluid (remember, engine must be running, transmission must be warmed up, transmission must be in neutral, and parked on level ground). Adjust as needed using
only ATF+3 or ATF+4, DO NOT OVERFILL!
What automatic transmission fluid should I use?- Use ONLY ATF+3 or ATF+4 fluids! Under no circumstances should you ever use Dexron or Mercon transmission fluids! One special note: many synthetic transmission fluids (such as Amsoil and Mobil 1) are approved for Dexron/Mercon and are also either ATF+3 or ATF+4 approved OR "recommended for Chrysler transmissions," and it is perfectly fine to use these fluids.
What can I do to increase performance and/or MPGs?- V-8 swap? See FAQ2 for list of possible mods!
Tune-Up, What to do?- Spark plugs (avoid "multiple-electrode" plugs [such as Bosch+2,+4]), spark plug wires, distributor cap, distributor rotor (located under the cap), air filter, PCV valve, and crankcase breather filter fuel filter are all things to change or at least inspect. Autolite 3923's are best for performance.

Where can I find more information?- As
gb6491 pointed out, many libraries have access to repair manuals, either in print, or online. AutoZone.com has a web page with some information (at AutoZone.com, click on "Repair Info" on the left side of the screen, and just follow the prompts)
Service manuals:
You can get hayens. It is simalar to chiltons in price and materail, it will run you $15 at most parts stores. For $19.00 you can get a full servace manul online at https://www.alldatadiy.com/index.html http://www.autozone.com/shopping/repairGuide.htm
OR get the paper Full book at any dealership parts stores for $80. I got 1, I love it. Or http://www.helminc.com/helm/homepage.asp?r
OR here are a few sites that have some good manual stuff.

Not what your looking for? Keep in mind that if your truck is close to that year, it's wiring is probably similar. You can also try
