55 State Sedan, wrap around windshield.
This is tied in with my previous post about anti-fog stuff.
I did a search and didn't find much on improving the stock defroster.
Has anyone tried [and succeeded] in making the existing defrosters work better.
The core is not leaking, and the motor is turning free [both speeds], it's just that the defroster is "weak".
I replaced the corrugated tubing under the dash.
In original form the airflow pattern was spread out wide and low on the windshield, and it cleared more of the right side than the left [drivers side].
I taped off 1/2 to 2/3 of the right side "Y" tube under the dash to direct more air to the left side.
That helped move more air to the left side.
Then I put foam backing rod [1/2" soft foam rod] at the outer ends of the vents at the windshield to direct the air more toward the center on both sides.
That helped direct the airflow.
There never did seem to be enough airflow ever. Is there another fan motor or fan blade that would move more air ?
If I am in the car alone and not too wet the defrosters will almost keep up and clear the window.
The other night with two wet people, the whole car fogged up and it became impossible to keep the winshield clear.
I drive this car rain or shine, luckily it doesn't rain often here.
Ahh ! The joy of owning and driving an old car.
