the temp slider very hard to move over? check the cable it might be stuck inside the slider.

My 97 TJ didn't heat well. Even after a coolant swap, it didn't get much better. Did a full flush, including the heater core. In the process, I found my water pump barely turned at all and started leaking after the flush. I couldn't turn the impeller at all.

Got a new one from the auto store for about $32.00. In the 2.5L, it is an easy job. Remove fan shroud bolts, then the fan. Pull both out. Remove serpentine. Remove water pump and replace. If it has an "R" on it, you have a reverse flow water pump (mine did).

Put it in, put in new coolant/distilled water, and the heater works great now!

Possibly a bad heater core or it still needs to be purged of gunk.

One way to check if it’s the cable is to unhook the cable at the blend door and see if by pulling on the door towards you it moves father then with the cable..
