There are several reasons for this.
1. There is very little insulation on the floor boards of the car. The
solution is to insulate it, like Kim's article describes.
2. There is a problem with the air flow within the cabin of the Bricklin.
There is NO way for any air to flow through. This causes a positive
pressure in the cockpit and the air stagnates.
3. The AC and heater boxes DON'T align. Consiquently, the air flow for
the AC is reduced by over 50%, so the AC can't really cool the car.
Terry has made new brackets for the AC box to let it align with the heater
box and increase the air flow to the cooling coils and into the cabin.
4. There is a problem getting the hot air out from under the car. This is
why Bob Hoffman has his mod of putting vents at the rear of the front
fenders. Terry is working on a different solution to get a better air
flow through the eng. compartment and get the hot air to exit from under
the car.
5. Do you have headers? There is a heat shield tape that you can wrap the
headers and the exhaust pipes with to keep the heat in the pipes and
let it exit out the rear instead of heating the fiberglass firewall and
floor boards. As these heat up, the heat is transfered into the cockpit.
(Again, here the insulation on the inside of the firewall and floor pan
WILL be a big improvement).
6. Have you had your AC system checked and or serviced lately? There are
several reasons that the AC may NOT be putting out what it can.
