I've changed my heater core and thermostat, but I still have no heat and the temperature gauge goes up. What else should I check?

What Louise said, but if you know something about what you are doing, make notes to tell the person who finally is scheduled to fix it. For several decades my husband has fixed and done autobody to the family cars. And 2 of 3 sons went to college tech for these same programs.
Neither of my 2 sons are employed in the programs above, use the info to keep their own things working correctly. Anyway, not sure if this is winter where you are, and the urgency of fixing the car is more than in summer time. If you are starting to fix things now instead of in the fall doing a full check list, I have to shake a finger at you. Catching something that should have been maintence back then was preventable. That being said, other things happen. Did you flush your radiator when doing the things you listed? Did you get things put back in the order they came off? Often a huge mistake. My guys use their phones and take photos as they are undoing, whether rebuilding and engine/tranny or just maintenence on different family cars.
This is a page about car heater blowing cold air. When your car does not warm up with the heater on, the thermostat may be stuck or the coolant may be low.
