Dash vent routing

[BullRider Junior Member Find all posts View Profile Close BullRider]

Just so I only have to do this once...

Can you guys let me know which outlets from the Fiero heater is for what. I'm sure that #1 is the fresh air intake and I'm pretty sure that #4 is the defrost, but I'm unsure about the other two. My car does have A/C.

Thanks, guys!

Re: Dash vent routing

Since you have it this far apart you should do the air as well. it is pretty easy at this point.

Re: Dash vent routing

I need this information also! I might suggest that while you are at this point,,,,,replace the heater core. It is located behind the right side and is very simple in this condition. It would be near impossible after we get the dash in. Very cheap (under $50) and well worth it. My core started leaking after just sitting in the garage for over a year. Antifreeze on your new carpet will create some god awfull heartburn!

What do you mean by "do the air"? I'm all ready for A/C. I just need to plumb the compressor, but that won't be until after I get it on the road and driving.

Can anyone let me know which outlet is for what?

Re: Dash vent routing

I believe the intake and outlets are as follows.

1 = Outside Air Intake (this would be on the other side of a Fiero windshield by the wiper motor)

2 = Flapper Door (when down, Fresh Air, the AC or heated air is directed to the floor or dash vents)

3 = Minimal Defroster (a little air is always going to the windshield but most will go to floor)

4 = Heater/Air Conditioning (Defrost door, this is always open and air flowing through it )

I'm going to have to play with it tonight. I could have sworn that #4 was the defrost. If I figure it out through trial and error, I'll post it here.

Re: Dash vent routing

Okay... here's the story:

#1: fresh air intake (route to outside of car's interior)
#2: vents and A/C
#3: heater (when I set to heater, I got air from here and from the floor discharge vents. I will just block this off completely in my build)
#4: defrost
