Another cooling fan problem

97 3.1 GT cooling problems driving me CRAZY

My wife bought her late brother's 97 Grand Am GT 3.1. The radiator was leaking b/c of overheating. Replaced radiator. Cooling fan wouldn't come on when I got the engine plenty hot. Checked fan motor. Replaced relay. Checked fuse. Now here's the weird part. While engine was running and hot, (close to but not in the red) I was playing with the cooling fan fuse, lightly touching the contacts, and the fan came on, ran awhile, then quit. Cleaned up the contacts on the fuse box but that didn't help. Got the fan to run a few more times the same way. My buddy thinks it's the fusebox but I'm not so sure. Any chance I could have been kicking something further down the line with repeated hits of current (like the temp sensor, relay, pcm, I dunno...) ? I've been an audio engineer for 35 years so I've had my share of intermittent connections, and this isn't acting like a loose wire. Any ideas?

More info

After reading tons of existing posts, went out in the rain tonight, started the car and cranked the A/C. Still no fan action. If I'm understanding what I've been reading, the A/C should have kicked on the fan, whether the ECT sensor is okay or not. Or am I wrong about that? And btw, where IS the ECT sensor located on a 97 grand am 3.1?

If your fan kicks in when you move the fuse, the connectors may have been distressed due to heat from resistance. A temporary fix would be to try to bend them back into place much like you would a female spade connector. If this is the case, you will need to do a permanent fix by replacing either the connectors or the fuse block.
