Floor heat blowing!

[Broncono]

I don't have the heater on, but I'm feeling it blow on my feet. Since I'm in San Antonio and it's 105 degrees, it's a bit of an issue. It isn't bad at idle but really starts blowing while on the gas. Thanks for any help!

May need to check to see if door is closing in heater box or if valve that control flow to heated coil is closing properly. There are seals in heater box that can be replaced on door.

Under dash or under hood?

Its probably the heater valve. The one that closes when you push the knob that says "pull for heat" If thats open you'll get heat on your feet, enough to nearly burn your toes!

You can always bypass the heater core and loop the heater hose back to the front of the engine to completely close the circuit.

I seem to recall reading somewhere that the Bronco heater shut-off valve doesn't close all the way.

But then again, since you live in San Antonio, it's probably cheapest (and will give you more room under the dash) to just bypass it and take out the heater assly.

Bypassing the heater doesn't change the workings of your cooling system, just takes the heater out of the loop.

When I first installed my Vintage Air, I noticed a lot of under dash heat. I thought it was pretty strange since the kit eliminates outside air to their heater. What I found was a lot of holes in the firewall for a variety of reasons and mods. Hot air was coming in from the engine compartment. I sealed all the holes with plugs or RTV. Insulation padding inside the firewall is a must. You'll never get the thing cooled down without it.

The door is inside the heater box--there is a tech article here
http://classicbroncos.com/tech/heater-box-rebuild
that describes rebuild. New seals are available (JBG, Tom's) for new seals. Easy to do and you can even have core cleaned up.

ALso I think the old tech valves were faulty. My '55 T-bird is a hot ride anyway, but helped when I closed of supply to heater.

Did you ever get this figured out? If not, BC Broncos sells a neat little valve to take care of the heat coming through the heater.

My valve doesn't close all the way, so in the summer time I pull the cable off of it and close it manually. On the rare ocassion that I do need it in the summer I just pop the hood and turn it on by hand. In the winter I hook it back up. By the way, I have done this on numerous old Fords over the years.

It sounds to me like the valve from Chuck is what you need. We have put them in all our broncos. Turn it off in the spring, back on in the late fall. BC is right there by Kerrville, it would be worth the drive, great people.
