I have a 199 Jeep TJ with 2.5 engine. My issue is with my heat and it’s two-fold. My heat works well at fan speeds one and two. My blower doesn’t work at speed three, but I’m not too worried about that. The main issue comes with fan speed four especially while driving. The heat is very poor and it’s lukewarm at best. I believe my water pump works fine since it gets to operating temp and stays there, and since I get heat at 1 and 2 I don’t think its the heater core.
The second issue is that when driving at mid-higher speeds (about 50-60) then vents will shut and switch to the defrost until my rpms come back down and speed drops.
Any help is greatly appreciated.
