No more cold feet while driving!

No more cold feet while driving!

Postby Hangard [OP] » November 26th 2009, 5:53pm

Seems I always have cold feet. Maybe being in Wisconsin has something to do with it, but its not even cold yet!

When the heater air is directed to the floor the passenger and the center ports work fine, but it seems GM did not want too much heat to the drivers feet. Well, its not enough of a balance as I have to turn the heat off when a passenger rides with me.

My fix? Seems to me that in a cargo van with two bucket seats that there is not much need for heat to be blowing out of the bottom center of the dog house. So on my recent cap, rotor, wires, & plugs change I did not put the duct back on after the dog house went on. Instead I did this:

What it is, is a 21" piece of flooring tube. Carpet has a cardboard tube, but this is from Flexitec - a vinyl that has no paper backing and nearly un-rip-able. Anyway, it is a 'plastic' tube ~4" diameter. I used a heat gun to soften it, kinda rolled it onto the diamond shaped port where the OEM duct fit on and now all the air blows to the driver's feet area.

I put about 600 miles on so far and it is great. I was concerned that it was not directed down, but the whole legs and feet area are nice and warm. I can now have the control on defrost/floor blend and the windows are clear and my feet are warm. Bring winter on!

I was having lunch in my van as usual at work, my boots were wet, old and wore out and my feet were damp and I was sitting sideways to get my feet infront or the heat.
So in other words, I like your solution.

Oh and sense then I got new gortex work boots. But that won't help when the temps drop into the 30's and below.

I HATE the unbalanced heat. My passenger always complains about getting cooked, while my feet are cold.
Also, what's with the knee level vents that barely blow?

It's nice to see someone work on a solution, but unfortunately this one doesn't blow into the back for passenger models, down onto my toes. I tried to get into the ductwork to come up with something, but could never figure out how to remove the dash. The joints between the duct pieces also now leak because they just loosely slide into each other and the insulating foam deteriorates quickly.

One day, when the astro/safari lineage rises again Chevy/gm is gonna love all this free information!!!!
and......yes I believe the concepts employed in the astro/safari are well suited for green power, a real MUV Multi Use Vehicle.

Now that was great thinkin and a true testament to us owners being determined to find a harmonious balance between our astroerotica obsession and functionality!!!!

There ya go thinkin with yer HEAT stick jimmy!

Thanks a mill great solution and Happy Holidays

I did not cut a hole in that bracket, it simply blows through and 'dumps' the air near the bottom of the steering wheel.

Was outside for a while yesterday before the hour drive north to the SIL's. Feet got a bit cold and it took for ever to warm them up on the drive. The ol' lady was doing her make up on the drive so I had some quiet time to think about this ducting thing. I had the idea of using PVC pipe, which you can heat and mold to shape, add in a Y to direct it to both foot wells and put a gate valve in the drivers side feed close to the Y so you could have even more control of the heat flow from one side or the other. Figuring the heat flow to the drivers side will be more of a direct line where as the pass side will have to turn back on itself.
