Replace thermostat and check for coolant in your oil. If coolant is found in oil, then chances are a bad head gasket.

I have a 96 jetta after replacing the water pump and upper radiator hose it over heats what could be the cause of my car over heating

Assuming the water pump is working correctly, my first guess would be air in the cooling system.
It has to be bled after repairs are made to get the air out and make sure it is full of liquid coolant.

Heater stops blowing heat and temp gauge goes up! Heat blows hot again and temp gauge goes down

This is usually caused by air in the cooling system. While the engine is cool, check your fluid level in the coolant tank. Then check the radiator to make sure it is full. If both of them are full, the system has to be bled. To bleed the system, take the radiator cap off, start the engine. If there is air in the system it will bubble out and the fluid level will drop, add coolant until this stops.

Can a new thermostat fail? I put in a new thermostat, water pump is about 7 months old, radiator about 6, coolant is new and full, fans turn on, yet car would start to overheat regardless of idle or...

Easiest solution is air trapped in the cooling system. Make sure you have bled all the air out of it. If it has been properly bled then it might be your head gasket or a crack in the head itself.

make sure system is well bled of air. Open radiator cap and start engine. Run until hot and thermostat is open (coolant flowing in radiator. Keep radiator full and also open any bleeder ports on thermostat housing or in hoses until no air comes out.

Bmw 318i. Car was overheating although coolant full. Bled radiator and now its ok but now heaters inside car blows cold. any ideas i can try please

Sounds like the thermostat has stayed closed you will need to change it as it will blow the head gasket, very common on this model.

Also when you bled it though you may have left some air in the system this would also stop the heating working, they can be a pain to bleed through keep sqeezing the water hoses as you are bleeding it through and do not bleed it from the lower part of the radiator as it will be hard to get the air out as air will stay at the top, you should bleed from the top.

My car is not blowing this possibly due to it having only water in the radiator and no coolant/anti-freeze?

No, that is not going to cause you to have no heat. You have some other problem, be sure the rad. is full. Look at your coolant temp gage if it shows normal temp you should have heat. Try and check any fuses for a blow fuse. Give us more info.
