1997 Dakota, not much heat
#2
Welcome to the forums.
Are you sure the engine is reaching normal temp? The thermostat could be failing.
A common problem is a partially clogged heater core. You can try to flush it. Disconnect the hoses and run water through it, then add some radiator flush and let it sit for a bit, then flush it some more.
Or, if it's been a while, flush the entire system.

I am having the same sort of issue with mine. I have a 99 with the 3.9 and I barley get the temp guage into the normail operating range. It has been gettinbg colder here and I dont have a long commute so I have even tried pluging in the block heater but no success. Any one know what the stock thermistat is set to crack at.

That is a common problem. Seems as if the heater core gets blocked or clogged up with slimy gunk. When this happens you will get very little hot air, or NONE. I usually back-flush the heater core about once a year on my 99 (V8) Dakota, which tends to keep the hot air moving fine.
A water hose will do the job, but I have found it works better to put some water in the lines and use a air compressor to blast the gunk out. Usually takes 5 minutes to get everything ready and about another 5-10 minutes to flush it.
I should take the time to do a total flush, but I have been living life in the fast lane.

Yup.. had same problem with mine.. did a back flush on the core spit out brown crap and then ran the hose till the water was clear.. then flushed opposite way.. put back together; burp the system and boom had heat..
Only other thing is to make sure you have the right T-Stat and that it's working. You'll get less hot heat off a 180 than a 195 of course.

Seems the t-stat needs replaced. Some other replies probably have good engine heat but it is not transferring through their heater core, thus back-flushing helps them.
Not sure if you want the 180 or 195 t-stat... depends what was working well for you before.
My $.02, good luck!
