Ok here is the low down of what has happened. I bought new spark plug wires and in the process of replacing them I had to move to heater hoses around a little bit to get the wires situated. After i got all the wires replaced and i took it for a test drive i noticed the heater wasnt working now. so i go under the hood and checked both hoses (inlet and outlet) and the outlet hose was not near as hot as the inlet. so i pulled both hoses off and what i found inside is kind of disturbing the inside of the hoses were lined with some sort of hard crusty stuff about 1/16" thick, dark brown outer layer and yellow inner layer. My guess is that my dad (previous owner) tried to stop a leak with that leak stop stuff. Anyways I guess what happened is when I was moving the hoses around the crusty stuff crumbled and possibly clogged up the heater core. So the first thing i did was hooked up a water hose to the "Outlet" side with the heater on to see if i could backwash that crust out of there, and water came out the inlet side without a problem. Then I flushed the entire system to get any remaining junk out and replaced both hoses. So does this mean that the heater core is not clogged even though the outlet hose is still cooler than the inlet hose? When I turn the heater on all the way to 90 degrees it still blowing cold air and I can hear the compressor kicking on and off.
