Default C68 Blower Control Module

Don't know if it's common knowledge, C68 blower module in expensive new, like crazy priced. Turns out anything GM with auto AC from 80 something to early 90's uses the same module. Buick, Ods, Pontiac, Cadillac. I was out at LKQ for something else and found a Olds 98 with the hood up and noticed how it looked. Found a caddy and it looked minor different but same plug and mounting. Now I have a spare for $2

I also picked up a couple of spares from cadillacs. There were two different modules used, early and late. They look the same except the late ones have one missing pin for the electrical connector. It is the compressor relay. If you try to use a late one on an early car, it fits in place but the compressor will not turn on.

I got one off fleabay a year or so ago listed for a Jeep Cherokee for about $13 shipped to me. Same exact item as for GM cars. 3 pins, works great.

For what it's worth, I just looked at the original one I took out (don't know why I saved it) and it is stamped Delco with a part number, then underneath that it says Japan, where probably all of these were made.
