Hi guys,

I've been a proud owner of a celica gt 2000 for 2 years now.
When I bought the car it had some damage, the sunroof was sealed etc.
I fixed all these problems as of yesterday!
I wanted to start working on my seat heating when I realized I couldn't find anything about it.
I just assumed this was stock but it's clear to me now that it isn't.

At the moment I have 2 buttons for heating on the driverside and 1 on the passenger side.
When I push the buttons nothing happens.
I don't have any experience with this and I don't know what I could do to make it work again or check where it is connected etc.
I really don't want to try and take out the buttons to trace the wire, they look professionally installed and I don't want to damage my car.

Anybody got an idea on how to fix this problem?

Ps. I got the 6 speed celica with climate control and leather seats.
