I have Hyundai ix35, 1.6, 2012
Today I pressed rear window defroster button. Everything was fine until I wanted to turn the button off - I can't release defroster button. When I click again on defroster button - nothing happen.
What could be the cause?
How to disassemly defroster button?

 

Those switches are not made to be disassembled.. If you feel it is broken, get a new one and replace the defective switch.

 

Ok, I bought new switch. How to pull out the button? And how can I replace it?

 

Because all vehicles are not the same, one has to rely on one's own mechanical ability or obtain a manual that provides the individual instructions io replace some parts.
