Okay, for once, I'm asking an easy question!

I did my footwork, and figured out that I probably have a bad foam tube for my ACC sensor, since I did a search and found that I have the proper symptoms. Whenever I turn the car on (it's getting colder!), the heat engages just fine.

Here's the problem:
* Car starts, heat works just fine.
* Get moving, car heats up on the inside. Whew, that 300D can sure generate a lot of heat!
* Car is now sweltering inside! I turn the fan from AUTO to Low to compensate.
* Vents suddenly blow ice cold air, and the heat won't engage again until I turn down the dial significantly. Turning off the car, waiting for a bit, and turning it back on, seems to "reset" the dial.

From what I read on these forums, this is probably a disintegrated foam tube, behind the glove box, right? A forum member recommended "5/8 OD, 1/2 ID H/C PEX tube" to join the two tubes together.

Is this my problem? If so, how difficult is the glovebox removal? I imagine it's just a handfull of screws, right? Is this something I can do without taking off the kick-panel, and simply fix it in the Home Depot / Lowes parking lot?

After this, I need to fix that windshield leak, get new glow plugs, and my car will be 100% "winterized"!
