I have a 91 4x2 Dakota. Currently I have an issue with the heater. I can let the truck warm up for 20+ minutes and the fan is blowing out luke warm air, if I drive it, it will get warmer. But I can leave the fan on full blast with heat and it never gets overly hot in there. Would this be the thermostat? Also anyone with Dakota 3.9's or 91 or later Dakota 3.9's have you put a glasspack on and how does it sound? Should I just keep the truck quiet or does it sound good with the glasspack.

A t-stat that opens too soon would be one possibility; and the first thing I'd check. Could also be a gunked up heater core. Sound is subjective - some think a 6 with a glass pack is trying to sound like a v8; it will sound like a noisy 6.
Lead, follow, or get out of the way

Buy a Prestone flush kit so you can backflush your cooling system. Use some cleaning chemicals too.
That should clean out the heater core.
If that doesn't fix it, then install a new 195 degree t-stat.

I just removed my glaspack because my girlfriend wouldnt ride in my Dak because of the noise. I personally think it sounded good. I replaced it with a Flowmaster 50. Its quite a bit quieter and still sounds good.

Note: Backflush really means in the opposite direction of normal flow. There is a procedure on this site, maybe a member can link, that discusses flushing from the outlet to the inlet side of the core. It is an instant fix for the luke-warm blues.
The Prestone kit may recommend normal flow installation which won't get 'er done. You can get hose adaptors at your basic hardware for a couple bucks and nix the kit.

Fix to original question

Here is an answer to the original question about the posters heater core. It is plugged. I had the same exact problem. I had flushed out my coolant system several times, but still no real heat coming from the heater. I then finally thought about it and realized the the convential way of flushing out a coolant system does not really flush out the heater core. The problem is that when you flush the coolant system out you normally connect the flushing water to the inlet side of the heater core hose and then backflush the system out through the radiator cap. This works fine for the engine and the radiator, but does not backflush the heater core. But for less than 99 cents and about 15 minutes you can easily backflush your heater core yourself. There was a suggestion on an earlier post to just reverse your inlet and outlet hose on the heater core and that would backflush it. This is true, but the gunk that is clogging up the heater core will just get flushed into you engine and will probably end up right back in your heater core. What you have to do is get a 5/8 inch female garden hose adapter. This can be purchased at just about any hardware store. Make sure it is the kind that slips inside the garden hose. Then with the engine cool you need to disconnect the outlet hose of the heater core from the engine. You need to do this at the water pump connection, which should be on the driver's side of the engine. Then insert the garden hose adapter into the end of the hose. Then disconnect the heater core inlet hose from the engine connection. On my Dakota this is easily done at the splice that is on the passengers side of the engine. This splice is where you normally connect to flush out the coolant system. Then hook a garden hose up to the outlet hose and turn on the water. Have someone help you turn on and off the water as you flush out the heater core. Try and collect atleast the first 2 gallons of stuff you flush out and dispose of this according to your local laws. After the first 2 gallons all you should get out of your heater core is dirty water. This should be ok to just dump on the ground but make sure first. You will probably have to flush the core for a good 5 minutes to fully clean it out. Then reconnect your heater hoses as they were and enjoy the heat.
