1996 Ram 2500 Van no heat
Hi. We have replaced the tstat, and have cleared heater core, but still no heat. The radiator was replaced before we bought it. Front hose at heater core gets hot to the touch, and rear one does not. Also, when we disconnect these hoses rear hose barely trickles, and front hose flows even when we take that one off last. I've noticed the a/c compressor kicks on and off. This is a '96 Ram van 2500. Any suggestions will be greatly appreciated. I did a search, and can only find info for later models. This model year is compatible with 94-97

If there is air trapped inside the system after core flush and changing the thermostat (hopefully the new one is good) , one thing you can try is purge or burp the air out. There are videos on youtube and lots of threads to read on how to do it.
I'm not expert but have had to do this same thing with mine. Better to begin with is to have gotten a thermostat that has a bleeder hole in the diaphragm already.
Basically you'll want to get the front of the van pointing uphill if possible.
Engine cooled down and take off the radiator cap, turn the heat on high and all the way red, start up and let it idle till reaches operating temp, just a few minutes. When/if the thermostat opens you'll see the coolant begin to flow as you look in the radiator and hopefully have some trapped air noticeably get pushed out seeing some bubbles and drop in the level of coolant inside so have a little extra coolant nearby to top off.
2 people easier as one can watch while one gives it some help by running the throttle up a little bit to increase flow and know that some may spill out the opening in the whole process so be prepared but let it ( but don't go overboard) until no more obvious air is being pushed.
If things go well you've seen trapped air escape in not too long a period and can top off the level of fluid and replace the cap. Make sure the reservoir is to full mark too and hopefully you now are getting some heat.
Take it for a drive. After cooled again recheck coolant levels.
hope that might help
