heater help

Post by GEODAVKY »

I've got all the controls set as per the heater diagram on my 1967 330 GT 2+2 for floor heat, but only get cold air coming . Warm blows out for defrost when controls are moved to defrost. What could be causing the floor vents to not get warm air?

Perhaps the hose from the heater box isn't attached to the vent hole in the kick panel. Does this happen on both sides?

Sounds like rotted vent hoses to me. If you have the same brain-dead design that I have on my 330 GTS, then all you need to do is to remove the fender guard, and replace the 4" hose.

A word of advice, based on my experience with my heater boxes - when you are in there, resist the temptation to take the system out to overhaul it.
