SUCCESS!!! :party36::party36::party36:I have heat, good heat, not that crappy kinda sorta heat as if I had a window cracked going down the highway at 60mph type of heat...but real heat! And man what a difference, even in just the 30 miles traveled so far last night and on the way to work today, I can really notice a difference. Its the first time in many years that I can remember the motor has heated up past 170°. Me likey.

pleas use a 195° thermostat please.

I concur! I was sure to ask the parts guy if the new part matched the OEM or if there were multiple listings, but he only had one listing so I made an assumption it was the 195°. I appreciate the clarity and as always, your knowledge is very much appreciated Sunlit!

Well turns out the problem is I have a hole in the plastic box and the ac condenser is busted up also :(

I filled it with foam as a temp fix, so the hot air doesn't escape.
Fixing the condenser is a big job am I right?

Hole in the condenser or evaporator?? The pic is your evaporator

do hoses 16 and 18 get as hot as the the rest of hoses at least? look at the part below and notice the crank on it. when you turn the temp setting from max cold to any other setting that crank should move. do you see that happening?

I have been fighting the heat coming on and off in my 96 Tahoe for months. It started with a cracked heater water valve which I replaced followed by a thermostat and finally the blend door actuator. From this post I gather that the vacuum to the heater valve exists to shut off the flow of hot water to the heater core so I finally pulled off the vacuum hose and plugged it. Voila, I have heat.

I'm not sure what the core problem is but I'll figure that out later. The point of this post is to thank all who contributed especially SunlitComet.
