Hi, the rear window defogger switch of my car is defective. The parts office asks for $45 for a new part, and I cannot find any other office in my country. Therefore I decided to use a common switch. To this end, I had to find which 2 connectors to connect, because the original switch was connected to 4. I disasembled the original switch and I noticed that it looked like a common on-off switch connecting just 2 of the connectors. I came to the conclusion that the other 2 where not used. Maybe they where there for a different version of the switch? Because the connectors where hidden in a plastic enclosure, I extended them using one 5 inch cable for each. Then I connected a usual on-off switch (13Ampere, 240 Volt) to these extensions. Now when the switch is on for about 1-2 minutes, the defogger works, but the plastic enclosure melts because a lot of heat is eminated from the original connectors and from their extensions. I do not think the resistance of the extension cables is high because they are thick copper wires I took out of a laundry machine computer! Any one knows what am I doing wrong? Any suggestion how to make the switch work?
