My 92 OCC blower control module (it has climate control) appears to be bad. A direct replacement from the local parts store costs over $200, but RockAuto offers a slightly different one for 90. By slightly different, I mean instead of having a 4 + 2 pin setup, they have a 3 + 1 plug-in and the heat sink looks a little different. I saw that somebody had used a RockAuto version before, but no mention was made of the different pins, so I don't know if RockAuto changed their part number over the years. Anybody know if this new one works with less connections?

I may have just answered my own question. I noticed there's only three wires on the one plug and one on the smaller one anyway, which would suggest the 3 + 1 pin module RockAuto offers will work fine.

I can sell you a used one for $50 shipped.

Looks like it was misdiagnosed. I guess I need to find some wiring diagrams so I can figure out what's really wrong. The fan works with voltage applied to it, but it's not getting voltage on demand. The control module has one wire that's constantly hot but nothing changes that through the controls. I swapped controls with a junkyard part but no change. Any enlightenment would be greatly appreciated.

Did you check the fuse?

On the driver side of the dash? Yes, all of them are good. For some reason I don't get any power to the one that says courtesy or ECM in the bottom row, but the inside lights work and the car runs.

The fan fuse has been known to heat up to the point that the fuse block partially melted, and the fuse no longer contacts the clips in the fuse block. I believe it is fuse 6.

I will have to check that when I get back home. I know the fuse is getting power to both sides of it, but maybe it's not transferring it to the other side of the block. I never really got to use the fan after I bought the car. It worked when I was test driving it, and when I got it home it never came on again for me.
