Ok. The fuse you need to pull is actually 19, its a 10 amp. Pull this fuse for 10 minutes, and then start it up and let the control head go through its calibration without shutting the car off. If you still don't have heat you may need a bcm, a blend door actuator, orr the blend door itself may be broken inside the heater box. Any of these things are not unheard of. I have replaced a couple bcms for this problem in the past, but the actuator or broken door would be more likely.
