I had a little trouble understanding what you wrote, so I'm going to try and repeat what you said a little more clearly..

You are saying your heater core doesn't seem to be clogged because you were able to spray water through it. Also, the heater controls are functional because when you move the heat/cold **** inside the car, it opens up the valve to allow coolant into your heater core.

Does the car itself heat up to operating temperatures?

so you got no heat and don't know where to start.... well the simplest thing is.... IS THERE ENOUGH COOLANT IN THE ENGINE, AND WAS THE heater set to full hot when you BLED the coolant system and let the car run to reach two fan cycles????

I bet it's just air locked

sorry i was tired the first time i wrote that..

i think the coolant is low.. i was under the hood and noticed the cable was off the valve there behind the engine to the heater core unit.. i moved it in the hot postion and it worked..it just seems not hot enough.... i think maybe the coolant is low and causing low heat issue's

low heat also could mean the heater core has started to lose fins and can't transfer heat as well.

ppl that get into my car always complain how ****ing hot it is... they say it's like having a heat gun blasting in their face.

visually inspect the heater core, and make sure it's properly bled and there is no air trapped in the system.

was your car up to temperature, and is your thermostat operating properly, ie, you actually come to temp and stay at bout half all the time.

put the heater on full hot (make sure the valve is open to the heater core) and let the car run for two fan cycles (about 1/2 hour) while topping up the coolant and bleeding it at the bleeder nipple.
