After driving car for a while and turn heater on I get heat for a very short time then it turns cold. You can turn car off and restart and again you will get heat for a very short time and then it will turn cold. You can repeat with the same results.

Check fluid level in radiator, refill as needed and bleed air out of system.

Step 1 - A heater cannot operate unless the engine is full of coolant/antifreeze. If coolant level is low check the system for leaks.
