I replaced the heater core on my 2002 dodge grand caravan and the thermostate on a 3.3litre and still have no heat can you explain wat the problem is thank you

Check to be sure both heater hoses are hot and close to the same temp, you may have a air pocket in system.If they are make sure your temp door is working right inside.

1999 Dodge Grand Caravan heat is cold

There are two possibilities, one is the thermostat. Many people remove them which spoils the whole heating / cooling system. Since you changed the thermostat, I would check the heater valve on the heater which allows the hot water to circulate through the heating system.
It may be necessary to remove the heater box and flush the heater core since you talk about a lot of rust, which could have clogged the heater core and / or the pipes leading to the heater.

Is there some type of fuse on my 2003 Dodge Grand caravan that I may need to change if it isnt blowing warm air, when the heat is on?

Hello, if its not blowing hot air its probably either the thermostate is stuck open or your heater core is stopped up.

No heat

You may need a GOOD new thermostat. I had the same problem twice on my first generation Dakota. The problem for me turned out to be the DODGE thermostat I used to replace the old Dodge part. I went and got a Stant brand from local auto parts store using the standard temperature spec and quit shivering the next time I drove it. I don't know if your engine is a Dodge or Chrysler engine, but it sounds like the same thing.

No heat and thermostat light just came on. What's wrong?

first check to see if there is proper amount of coolant in the reservoir and then put on gloves while engine is running squeeze upper radiator hose together if hose trys to open up while holding it the water pump is probably still working and when was last time drive belt was changed because it could cause this problem because it is slipping
