Radiator fan inop

Well after more troubleshooting this is what I've found. The fan trigger wire from the ecm has continuity to the fuse box but not through the box. So I need a fuse box for sure. The a/c compressor clutch is burnt up so I need a compressor. The fan does not come on at 200 degrees which I assume is due to the fuse box. Now I just have to decide if a car with 215 thousand miles is worth the expense and work or if it's junk time.

Then try tightening the bolts in the fuse box. I would loosen them then crank them down really tight, past the point you think something will break.

Well I replaced the fuse box with no luck so I ordered a refurbished and reflashed ecm and low and behold the cooling fan comes on at 217 degrees. It still does not come on with the a/c but I suspect that is because the clutch on the compressor was destroyed by high head pressure due to no cooling fan. I also discovered tonight that the temperature gauge only reads about a quarter of the way up at 217 degrees. I am going to change the temperature sensor in the morning. Now I have a code P0315 and a check engine light due to the new ecm needs a relearn for the cps. I will have to check around and see if I can get it reset. I tried the manual method but it didn't work.
