Could be that your heater core has died. I would look into getting that replaced to fix the issue.

first put the cap back on, next before you put it back start it cold with cap off, when it reach's Running Temp, you should see the water flush like the Tollet then start moving, if it does not do this, or if it is moving when it is cold you need a new Thermostat this is a common Problem with them

Run the self-test on the EATC. The blend door is notorious for going out. Code 24 & 25 are faulty blender door.

you should never use a fuse that is larger, or smaller then it has in it, unless you like wiring fires ?
