It was pretty strange what came out. It wasn't mucky coolant or large chunks of debris, rather it was a lot of tiny pieces of what I would call dried up coolant. There was probably just enough of them to fill a milk cap with. That's all it took to get the heat nice and hot again. I will be...

Great news! The heat is working terrific! It's almost TOO hot! haha. Just kidding of course. A buddy of mine has an air compressor, so we used that (120 PSI or so) and did a back flush on the heater core. It was most effective of getting the junk out of the core when it had some coolant...

Thanks again for the help. I had a glimmer of hope tonight after I flushed the heater core with a garden hose... it was actually warmer than it has been since the whole fiasco started. Eventually, the hope faded into cold air. This time it took a LOT longer to do. I also noticed that the...

That's a huge help. I will be taking a look after work tonight and see if I can make sense of it. It's interesting to try to read this diagram however. The hose marked 87246E leads to... nowhere? haha. Is it possible that the part labeled 90467-23009 attached to the hose labeled 87246E comes...

Thanks! I hadn't realized I was looking in the wrong place. By any chance, is there an annotated image to point me in the right direction? I'm afraid my eyes aren't very keen to what's what... I would like to flush the heater core with the water hose but want to know for sure what hoses are...

I really appreciate your time. I have already checked that particular cable, and it's connected properly. It doesn't sound like it takes that much time to flush the heater core, but my concern is that both hoses on either side of the heater control valve are hot and the same temperature. If...

Another observation... One more observation... maybe it will help put a nail in this thing. When I have the fan control turned to the "OFF" position and the vehicle is moving, I can feel some good heat coming from the vents. When I turn on the fan, it becomes simply gets cold after 10 seconds...

Updates The vehicle just got out of the mechanic's shop after an attempt to purge the air bubbles. Unfortunately, this didn't resolve the issue. 30 degrees, snowing, a 3 year old in a child seat in the back, and still no heat... :) My next thought is, is it possible that the internals of...

I don't think I did the burping correctly the first time (I cannot confidently say where I had the heater controls). Besides, all I did was prop it up on a curb and open the radiator cap to see one bubble before it started to overflow. Since then, I've seen several different methods for doing...

If I'm thinking right, isn't that the valve that's attached to the firewall on the engine side, near the top? When you slide the heater control left to right, I can visually see the cable move the arm on the valve left to right. From the looks of the image (thanks, by the way), it appears...

More information... Additional details (after a quick, midnight drive around the block and on the highway shortly): The rear heater behaves the exact same as the front. After checking this thread, the second cable under the glovebox seems to be operating correctly. I tried to use my hand to...

I sure appreciate the quick response, but the link you provided doesn't tackle the same issue. They describe having ONLY hot or ONLY cold air and nothing in between. I'd be fortunate enough to have that problem at this stage of the game. :) It's a '97, so no digital controls, just the good...

This is a problem on a 1997 4Runner Limited with 200,000 miles. The mechanics that I've visited in town with are clueless -- let's see if you guys have some other ideas. I had one mechanic take a look, and he replaced the thermostat which seemed to work very well until half hour later when I...
