2002 astro van rear heat problems ?

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
