93 Explorer, No heat???

Ok so my 1993 Explorer EB 4x4 with A/C isn't spitting out any heat. Once the thermostat opens and its up to normal operating temp the blower motor just spits out cold air. I have installed a new heater core, radiator, and thermostat. When I checked the hoses going into the heater core, they are hot but still no hot air. I have read though some posts and from what I can tell there is a blend valve that may be at fault here, also I found this part on the net that I am thinking may be an issue

Can someone please point me in the right dirrection? I have never come accross this type of problem before.

Thanks

Your link takes you to the parts site but it doesn't show the part. Have you checked and made sure you don't have any vacuum leaks? Any difference in the air flow when trying to adjust the temp?

Well the problem ended up being a bad water pump. Went to pull the pump off and the impeller wasn't even attached to the pump shaft.

Thanks
