All windows in my car have to be manually roll up and down. So, after research on internet, found similar diagram for auto roll up and down windows using FET.

Would be very pleased if someone could expand the details of circuit inside the FET box so as to enable auto functions.

Awaiting to complete the project during this lockdown.
Thanks in advance.

Sorry for the delay. Looks like we have a couple issues. First with this being a 2021, the manufacturer has not released any information to the aftermarket about it yet. They have 12 months after the vehicle is launched to release that so we can't provide specifics about it yet. The other issue is we don't have the i20 in the USA so they won't provide the manual to our system of Alldata.

With that being said, a FET is just a type of transistor that is used in many types of electronics.

Here is a website that gets into the general idea of what a FET is and does:

https://www.electronics-notes.com/articles/electronic_components/fet-field-effect-transistor/what-is-a-fet-types-overview.php

Lastly, in most all automotive settings the FET is internal to the junction block or body controller and is not serviceable. So if there is an issue you replace that entire component and get a new FET contained with in it.

Hopefully this helps. Thanks
