Can you feel of the heater hoses under the hood? Are they hot? Is there air flow through the vents?

As long as there is some sort of air blowing, cold, semi warm then try this. I had the same problem on my 2001 s10. As long as there are no antifreeze leaks any where such as chocolate milk oil on the dipstick, antifreeze on the ground and so on, then you should try reverse flushing the heater core. Not to hard to do. Take the the two heater hoses that run into the fire wall on the passenger side of the truck off. One is an inlet and the other an outlet. Take a garden hose with a nozel with a jet setting on it and hold it up to one of the holes of the heater core. Does not matter witch one first as you will do this to both holes. Hold the water pressure for about 2 min. Or so and the water should come out the other hole. You will heare a girggle sound. Take the hose off and put it in the other hole on the opposite side of the one you just shot water into. Hold about 2 min. And the heater core should be cleanded out. This should fix ya right up and you should have burn ya out of the truck heat. Good luck. As long as there is no antifeeze leaking out anywhere then this should do it. If there is antifreeze leaking on the ground prior to this method then the heater core may be shot. Let me know what you find out. Feesh13937@yahoo. Com
