I have a 1996 Dakota with the V-6. I've had no heat for 2 years. The heater core was plugged so I had a back flush done and nothing would go through. I recently installed a new radiator( it was plugged) new t-stat & new heater core still no heat. The heater hoses are basically cold. I'm stumped, could the hoses be clogged? The water pump is 1 1/2 years old. I'm ready to trade it in!

Dan's original post in case that may help any of you:
-----
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.

If I have a faulty t-stat will that prevent coolant from flowing through the heater hoses?

I should also say that I had a major overheating event and never changed the t-stat afterwords, could the overheating ruin my t-stat?

My question is... I have heat, but a few days after I got this truck last week, the blower quit working. I noticed the blower would seem to cut off and on a lot during operation the day we were driving it home. Now nothing! It puts out a lot of heat without the blower on, so I don't think it's the core. Fuses are good, checked and changed. Blower motor or switch? That's the question.
Thanks!

I also tried Dan's suggestion today. I got 2 5/8 hose adapters. One to hook into the line off the water pump. The other I put at the splice so I could hook up a garden hose to catch the first couple gallons of crud. I flushed for 5 mins after I got clear water coming out of hose. Hooked it all back up and TA--DAAAA heat glorious heat! Thanks Dan.

I have the annoying no heat prob on my 97 V6 4X4, with 0ver 140K heat was great till recently. Now it is lukewarm, blower works fine. I thought the radiator needed flushing and took it to a shop (big mistake) since I was too busy with the holidays to do it myself. After reading these posts I had specifically told them to flush the core. They said "no prob" well $90 later still no heat. they didn't have time to replace the t-stat that day, so today (2wks later)I did that. When I drained out some coolant to do this it looked cruddy and had a lot of sediment......Im thinking NO way did that shop do any significant flush on my system, much less do the core. Plus, after looking at the hoses to the core, its pretty obvious no one touched it. SO....I am going tomorrow to get the adaptor to do it myself.
It will be interesting to see what comes out of there. I plan on taking the initial gunk form that, and the cruddy coolant I got out today, to discuss with that shop.....
Im sure you've all heard the saying...."hell hath no fury as a woman against those that mess with her and her truck."
Im hoping that will be the end of it....the MEN around here thought they should dismantle my dash today to check everything out.....after 2hrs of grumbling and mess....still no heat. "They" don't believe it could be the heater core, as suggested in these pages.
we shall see.

Hey Dan,
Thanks again for the quick fix, went from no heat to supertoasty in 15 minutes. The problem with my 93 Dakota 6 cyl developed immediately after replacing the waterpump and thermostat. I had heat before the change, none after. I thought the thermostat was defective so I changed that again but still no heat. Gave the heatercore a "dan" backflush and now I drive to town in my underware!!! :-)
