Yeah I will. The only reason I took it to this certain garage is because its pretty much right next to me; can drop it off and walk home. But they have a not so good reputation, and now I understand why. I will be getting a second opinion. The owners manual states that the blend mode is the correct method for normal operation, not recirculate.
Recirculate will not work unless the AC, or defroster is on, or vehicle is under heavy load.
I could be wrong here, but if you have the heater on , and hit the recirc button it will flash 3 times then go back to outside air. So unless you have the AC is on, and temp turned to full heat I don't see how recirc could work in regular heat mode.

Recirc on my truck works in all modes except defrost, does not matter if it's hot or cold on the temp wheel. The reason it won't turn on on defroster settings is because if there is moisture inside the vehicle it could steam the windows up rather than defrost. If I have selected a defrost option and press recirc, it blinks three times and goes to outside air like you said, but it will work on floor and vent modes.
I am pretty sure the garage was warming it up inside their heated garage, and recirculating the air to make it seem like it is blowing real heat, just to avoid doing the heater core. Either way I have no issues taking it to a garage that wants to do the work.

My 2000 does it, but only with the rear heat/ac... perhaps I don't have the 1.21 gigawatts of electricity I need to make it all the way back there

Don't forget you may also need to get up to 88 mph too....

I tried yesterday, but I'm in Jersey so it's hard to get going that good without smashing into 6 million other guys clogging up the highway in front of you.
But really though, no matter how I have the heat/ac set with the rear control, the air comes out a steady temperature of blah. I haven't really looked into it at all- this thread just made me remember that it does it.
Just went and picked the truck up. Heat appears to be working alot better. It gets hot enough now to just about burn your hand. I would say the heater core was indeed the culprit. The only downside is the top of the dash with the defroster vents is loose. Is this easy to take off and try to tighten back up, or is it normal? Also got a P0300 on the way home, so I gotta look into that but at least the heat is working!
