Check the coolant level in the radiator. If the coolant gets low enough the heater is the first thing to stop working. If there is plenty of coolant and the temp gauge is get in up to the half way mark than it's possible the heater core is just about plugged up. Your local repair shop should be familiar with flushing the heater core. I have had many successful heater core flushes over the years and it can save you thousands. If the heater core is successfully flushed it may not be a bad idea to have the coolant flushed at the same time.

Sounds like air in the cooling system. Try taking radiator cap off and letting the vehicle run with heater on high. As bubbles come out add coolant. This may take 20 minutes to a half hour.

I woild be checking the vent controls as if the ac is working and the core was blocked then the air would be cool when the heat was selected but not changing Fixing the heater has resulted in a /c not being good enough to cool the air if the vent is not properly selecting. The point is that if the vent selection is not working properly (vacuum hoses) then the 2 faults will be related.

please help with this problem

To warm your car, your car's heating system makes use of excess heat from the engine's internal combustion process. Diagnostic tools for car @http://www.obd2express.co.uk

your thermostat is stuck open ive changed a few of them and it is very labor intensive the part is like 20 bucks but the front of the car has to be removed to change it the fastest i can do it is 4 hours the first one i changed took 7 hours. thats why the dealership wants so much they do already know whats wrong its a common problem.

sounds like you need to either...add anti-freeze solution to your radiator...or worse case...coolant pump is starting to fail or heater coil is clogged..if coil is suspected to be clogged....do a radiator flush...reverse and foward flush the coil only...hope this helps

What temp thermostat did U put in????? Check and see what thw manufacture call for you car. Also check to see if any leaves are in your heater box, which is stopping the air flow. Some cars have and air filter on the inlet duct. It could be plugged. Check this out also.
Take the 2-heater hose off where the water goes into the heater coil. Back flush it with your home water hose, the oopposive direction that it normal goes. It can get stop-up. You can also flush your whole system by empting the radiator and put a can of old time comet into the radiator, and fill it also with water, let it run for 1-hour, the empty a,d fill with water 2 more times. Fill it back with antifreeze and go with it. This should clean everthing.

could be a pluged heater core back flush heater core. or heater controls aren't functioning properly
