Firstly, a thermostat that opens quicker will not give you better heat. Your heater core may be partially plugged causing a low flow issue. Another area to check would be the water pump impeller for corrosion or slipping on the shaft. Does the vehicle's cooling system operate well otherwise?

Most likely you have air trapped in your engine, particularly in the heater loop. You need to properly bleed the air out of your radiator cooling system. The hot and cold blasts of air coming from first hot water followed by air.
Read up on how to bleed air out of your radiator system. Some systems are very difficult to bleed.
If after doing a good bleed of the radiator system the problem returns, you may have a bad head gasket or other leak in your cooling system which is injecting air into the cooling system (radiator/water cooling system).

You have a problem wit the air temperature control blend or the blend door actuator motor, most times both are defective. The parts are located deep in the dash and as such the dash assembly must be removed to service the parts.

your auxillary fan is not working. this fan is responsible for cooling the freon that is being circulated in your cooling system... check if there are any loose wires in front of the engine bay.

the auxillary fan is located right beside your radiator fan.

Re: blowing cold - I'd flush cooling system and replace thermostat. Re: hard start - when was last healthy tune up? Plugs, wires, all filters including FUEL FILTER and run a good fuel cleaner through it.
