Hot cabin air???

[valiant]

Not to sure what it is as only got car last week etc. But there is like 2 small tubes "copper??" that run up the inside of the drivers side floor hump running behind the radio that is pumpin out a hell of alot a heat. Is this the tubing for the heater? If so why would it constantly be so hot "to the point if touched would burn" Thanks for any advice.

If your car has climate control and the air conditioning is on then you should expect this pipe to be hot, even if the temperature is set quite low.

If you haven't got climate control, then I expect that you problem is related to a vacuum leak or a faulty heater tap.

If you look down near where the 2 brass tubes are you will see a cable and clip arrangement part of which moves when you turn the heater dial to cold....anyway, it's not uncommon for this to get kicked off and out of adjustment - this results in the heater tap being on at all times. Good Luck.

Get someone to turn the dial from hot to cold while you watch the heater tap - the vacuum servo arm/lever should move....if not it means there is no vacuum to the tap. Another way is to pull the vacuum hose off the heater tap - it should be sucking strongly if on cold (or vice-versa). Both test with motor idling.
Good Luck.
