Using the air bleeder valve didn't do the job good enough.
Having own a third gen. TA. back in Alaska, this works.
Also go to Radio Shack and buy a infrared temp. reading tool. (under 15 dollars.)

i searched and found this thread and i thought what the hell, so i tried it and my heater works great again. it wasnt heating up for nothing. still have to figure out why i it only blows thru the defrost vents where ever the *** is at.

flow control valve.

My 95 Z28 has one also.
I'll get rid of it some day soon.

I've tried squeezing the lines and it didn't work. I'm going to flush the heater core with 2 bottles of Prestone super flush this weekend. Hope it works, if not then it will have to be replaced. I'm not a big fan of replacing it myself...but we'll have to see..
