No heat

Check the hoses going into the heater at firewall, if one hot and the other cold then there is a clog in the heater core or partial clog, If the vehicle has been sitting for any time sentiment may have settled in the heater core. you can try by reversing the hoses. See if that clears it up.
.

both the hoses are cold, switched the hoses, and looked inside them, looks good, also ran the car for few seconds while hoses off and water came out. bled the system again, and still the same thing. warm on driver and flat/ambient on passenger.

Removed the heater core, doesn't seem to have much dirt, but i tried to clean it up by running water in one side while it's off the car. is the water supposed to come out the other side quickly and freely? i cleaned it and cleaned it but there is only little water coming out of the other side, even with an air compressor. if i put in air from one side hardly any comes out of the other side..

The water should run through there equally. try changing the water back and forth.

I did it all kinds if ways, each side wont take more than few ounces and then water would run off, same for the other side, looks clean on the outside with no rust or dirt, that is what i thought is that it should run out from both holes, also both pipes coming out of the heater core are hot, my guess it is cogged up and mot circulating?

After putting it back same thing but a bit more heat from passenger.

I am pretty sure the thermostat is fine, temperature reaches optimal in the middle within normal time, no leaks or overheating.

It sounds like the blend door actuators are closing? Can you remove them to check the operation?

I can try the passenger. can you give some instructions on removing it?

Here are the instructions for removing the actuator. Check out the diagrams (below). Please let us know what happens.

replaced th heater core and all good on the heat, thanks for your help!
