Help!!!, no heat in the winter
 

So I have a 98 XJ 4.0
The heat has stopped working. I initially thought it was the blow motor, but I jumped it from the battery and it worked fine. I next changed the blower motor resister and changed it out. Still not blowing. It appears that when the heat is turned on it will blow hot, but I can't turn the air flow up. I checked the switch and it seemed fine. Does anyone have any ideas? Also the heater core is leaking and I am afraid to tackle that job. Does anyone know of any good resources for a DIY to show me how to change out the heater core?

Thanks

Bypass the core if you have to drive it. Plenty of heater core videos on youtube. Gonna be fun either way.
