You need to fix the coolant leak, then refill and bleed cooling system, then you will get heat and cure overheating problem too

it would appear that you will have to replace all items damaged during the theft attempt
as all the items are part of the dash assembly including the radio, I would consider a complete dash from the wreckers and that way you only have to hook up the wiring harness connections

Water pump. First make sure you have enough coolant and the reservoir system isn't leaking(or any leaks). Fords are hard to get air out of the system. I always over fill Fords because of air. It will usually purge out in a couple days. only getting warm at idle and hot going down the road is a water pump or something is still clogged up. IE.. heater core.

Double check your cooling system. Make sure it's topped up and that all the pipes leading from the radiator heat up during normal use, if not, you need a new thermostat.

That seems pretty normal, the heater works by blowing excess heat from the engine coolant. So the coolant has to be warmed completely for the heat to work, you can get a heater that plugs into your cigarette lighter that will heat the vehicle instantly.

If your engine temp reads warm then your heater core is clogged. Try flushing the system. If it reads cold then u need a new thermostat

Have your thermostat checked, sound like it is not working when cold.

check to see if your heater core is hooked up sometimes they leak,and owners bypass them.

This sounds like your automatic climate control is starting to malfunction. Check to make sure your coolant is full, and temp is not fluctuating, and when your vehicle is warmed up, try using the low setting and feel for air temp. Is it warmer than if you turn it up? When at idle the vehicle is not producing heat the same as if you are driving, putting load on your engine and more air/fuel combustion means more heat, which is why you can feel heat while driving. Ideally you should feel heat as soon as the engine is warming up, getting hotter as it reaches peak temp of 190-210 degrees. You can try to make sure your water control valve is not blocked, and all electrical connections are secure. This will be located close to your firewall and connected to the coolant tubes that run into your firewall to your heater-core. Also use recirc (setting)to try to summon as much heat as possible, however ultimately, you may need to take you vehicle in for service. If it only warms when driving defrost will be an issue. Good luck.
