heater

Hey guys, New guy here. I am restoring a 1975 Lemans with a 350. It was a hack job from the previous owner. Trying to restore back to its glory days. Problem: Heater control on the dash blows air but will not change location (vent, floor, etc). I traced the vacuum lines through the firewall and...

Hi everyone, thanks for all the support so far. The previous owner has bypassed one of the tubes on the heating matrix and left a pipe detached and can’t for the life of me figure out where is goes. It’s the pipes just behind the trans dipstick.

So I've been working on this car for quite some time. I'm going to give some background on the heat and a/c so you have a better understanding of the issue. So before I go the car running I had an old battery in the car and all it could power were the courtesy lights, headlights and, even the...

So I have changed thermostat both lower and upper radiator hoses are hot as well as both heater core hoses. Changed blower resistor and blend door motor. But I still have no heat in the car. Any suggestions?:mad:

I had my heater replaced a few months ago, and as soon as it was returned to me, I noticed a hissing noise when using the heat/air conditioning/vent. Usually the noise is only audible when on the higher air settings (3-4), and it doesn't hiss when going through the defrost vents. I don't know...

I was driving the Fiero and I gave it a good amount of gas while heading down the road, probably pushing it pretty hard but not more than I've done before. I slow down and quite a few seconds go by. Suddenly, smoke is coming out of my vents, although the temp gauge reads normal. I find a safe...
