No, that will not work. A restricted catalytic converter will need replaced.
No, the catalytic converter has nothing whatsoever to do with your defrost system.

It's not up to you, when to "make the catalytic converter to work"!... The catalytic converter will provide the chemical reaction alone only @ 400 > degree, no options! See/Google "how it works" and that will help you understand how and why!
I would not touch it except to install a converter.
I believe bank 1 sensor 1 is Passenger side before catalytic converter. sensor 2 is after catalytic converter. bank 2 sensor 1 is Driver side before catalytic converter. sensor 2 is after catalytic converter.
A catalytic converter changes unburned hydrocarbons into carbon dioxide and water vapor. It's a simple chemical process, and like most chemical processes, it will either generate or absorb heat so in this case, since the catalytic converter requires heat to change the state of the hydrocarbons, it either has to be heated or it will operate quite effectively using the exhaust heat. Note, if the engine is operating efficiently there should be very little for the catalytic converter to do.
Many of the compounds that make your engine oil work better on the INSIDE of the engine are also "poisonous" to your catalytic converter as your engine starts to use oil. The nice thing about catalytic converters, they burn unused hydrocarbons that come out the exhaust. You may not KNOW that your engine is burning oil until the catalytic converter gives out or even gets plugged up. Watch the oil level in the crankcase. If it drops with no evidence of leaking, it's burning and your catalytic converter will die.
A quality aftermarket catalytic converter will work fine as long as everything else is in good working order.
It must get hot to perform at it's best.
I meant to replace it. Sorry. At work so had to type fast lol. I was told to remove the drive shaft but the Chilton manual says to just remove cross member then unbolt converter.
It's Hot! It needs to be to work properly.
