I'm think'n mine's clogged up too; I hope that's what it is and not my heater core anyway...
she'll blow warm, barely... not quite like a heater should though...
I'd like to see what you find on this and how it works out!
unless I get to mine before you do, then I'll let you know, lol

I will let you know tomorrow or possibly tonight. I am going to go in some order to see if I can pinpoint it. I forgot to close a panel in the heater duct, so I am going to try that first, then I am going to pop the heater valve off and clean it and if it is broke I am just going to modify it to where it stays open the whole time, if that doesnt work I will do a new t-stat just to cover all that crap. So, one of those three should work, if not I am going start using this truck for target practice.

well supposely it's quite common for these heater valves to gunk up and clog, so that's just where I'm going to start, and while the hoses are off I'm also going to back-flush the heater core, just to be certain

granted one of them blew a HG in the past (my Isuzu) and left a LOT of deposites in the core; the other was just old (my 82 Monte Carlo)

I will need to include this in my quest to get a hot heater! Mine blows pretty warm and slow. Motor is workin overtime though!
Hope I can tear it all apart and clean out all the gunk..

Jjust as a note, be easy with it; I wouldn't turn the hose on full blast in there. You obviously want enough force to get the crap out, but if it's an old core I've seen it make them spring leaks before. I think that's been mentioned here on YT before too...

Why don`t you guys upgrade to the later style plastic heater valve, its very easy to do and you will never have to worry about it rusting through and leaking or siezing up, ive done this to a couple of trucks ive owned and never had any more problems with the heater valve.

so even finding one at the salvage yard is worth it to some.
for me, a trip to the pick-and-pull yard is about a 60 mile trip (each way), so hardly worth it in gas, even if I could put the valve in my pocket.

Lucky guy. We have quite a few yards. But there is one yard in particular, Alpi's. They have hundreds of these trucks and only sell parts for a premium. It seems they buy up all the trashed trucks and stock pile them!
I wish the local pick a part would get another yota in. Last time they had a 3rd gen it was stripped to the frame in days..

Problem Solved
I really need to quit drinking keystones while doing this crap. Ok, first thing first, the heater valve was stuck letting only about 1/4 of heat in, so modified the lever and this made the air A TAD bit warmer, basically for winter I took the cable off of it and just opened it wide open. Sot would be Full heat all the time!
Burpe it again since the core takes up alot of air, but the problem was i forgot to hook the black cable on the cold to hot lever, so I wasnt opening the flap by the heatercore. This was obviously a keystone light crisis.
thats about it, and ebay has a heater valve and pipes going for 5.99 as of yesterday.
now my heat blows hard and hotter than hell.
