Been having some electrical gremlins. I didn't drive the car for about three months because I was traveling, and the battery failed and took out the alternator with it, really the voltage regulator probably (my bad, I should've disconnected the battery). I replaced the battery and alternator (that was a fun experience, nice to know they used two different alternators, and that they are not interchangeable as the diameter of the pulley shaft is different on both models....GRRRR).

After that I got a CEL for the coolant level sensor, but when I checked it, it was fine, so I drove it as it didn't over heat until I got stuck in traffic and it did then.

I found that the electric fan wasn't coming on. I read through the threads here and saw that if you turned on max AC that the cooling fan was supposed to come on, and that was a good test to determine if the fan was working, but there was a chance it could be the fan relay module as well. I tried that, and no fan. I put in a new fan, and got the same results, so I'm thinking it's got to be the fan module. There's one on fleabay now, so I was thinking of grabbing it and seeing if that resolves the issue. I did use a volt meter on the fan module and could see voltage from the tiny wires that go into it, but nothing every came out of it.

I'm totally open to ideas

Also I tried to hook my Harbor Freight ODB2 reader to my Crossfire to see if it would give me a code for the CEL, but I get an error that it cannot connect, yet in my other car it connects fine....could just be that it's an inexpensive ODB2 reader....but I dunno.
