1998 Ram 2500 Heater Problem
I've searched around and found lots of forums talking about "sortof" my issue, so I thought I would post "exactly" my issue and see if any of you "more qualified than me" guys out there could help a brutha out.
I have a 1998 Dodge Ram 2500 Laramie. I bought it two years ago, and I've never had "good" heat.
The temp gauge never really gets to good running tempurature. (I'm not sure what the temperature should be but lets put it this way, at 12 oclock high is 210 degrees, My needle stays pointing at 10 oclock all the time. never goes higher.)
Anyway even after an hour in the truck with the heater on the whole time, I get luke warm air coming out of the vents. If i put it on high, I get cold air. I have to leave it on the third setting or I freeze.
I've changed the thermostat, I have the heat checked, and the hoses are hot, but none of the heat is getting in the cab. I've also checked the control doors and it seems their opening just the way they should be.
AC, I get lots of air, and its freezing cold. Heat, nuthin!
So what would cause poor heat?

Air pocket in the heater core. Par for the course for these trucks. Park your truck at a rather severe angle, with the passenger front being the highest point. Try burping the air out of the cooling system. (DO NOT open the radiator when hot, you get a VERY rude surprise.)
If that doesn't help, flush the heater core. Flush in both directions, ending with backwards. Then, trying to lose as little coolant as possible, hook both heater hoses back up. Makes a WORLD of difference on my truck. (having a friend help you makes this exercise much easier.)

Heater fix
I had the same problem.. I went to my local pet store got a low pressure water pump and did my own flush but that wasn't it.. Turned out there is a little ceramic block under the dash on the passaanger side. I for get the name of it but I changed it and wow what heat I have now!! You can call your local advance and they will more then likely know what it is called.

I would check the blend door again. Last year on my '98 the cable popped off the door and I had no heat at all. If you pull out the glove compartment you can access the door and see. I ran for a while with a vise-grip on the door shaft that sticks out the bottom of the heater box until I could re-attach the cable, but then, I had full heat or no heat , no in between.

Maybe try this approach?
Core Flush
I would suggest using a coupler and connecting an additional couple of feet of hose to run your outlet to a bucket instead of a jug next to your face. sheesh.
Also, when I was finished there was still a slight gurgle in the cab. Romped on it pretty good and the gurgle went a way...has not come back...and have heat.
Had the same issue...luke warm air at low and med low, cold any speeds higher. It really sucks after standing in a cold river chasing steelheads and your unable to warm your frozen toes afterwards...ya know?
