I have a 2002 Chevey astro van When I put the rear heat on the blowers blow but only cool air comes out what can i do or check to repair the problem

you want to check under the rear of the van and you will see a group of hoses and ac lines going up into the van, check to see that nothing has become lodged to kink the hoses. if thats all good i would have the coolant lines blown out with compressed air and that should clear any blockage, if all that fails you need to have your water pump checked
