I have searched a cooler switch (A/C switch) for my model in www.toyodiy.com and its part No. is 84660-95J01.
After I got the part,it confused me a lot.
Look from the new cooler switch ===> there are 4 pins on the upper row and 1 pin on the under row.
Look into the cooler switch socket ===> the 4 connector holes are on the under row and the one connector hole are on the above row. I mean the pins on the switch are opposite the holes on the connector. What's wrong?
