94 LT1 Blowing FUSE!
Its the car listed in the Sig.
The Fuse for the Coolant Fans keeps blowing and im gettting Codes 77, 25, 26. I have checked all the Grounds and they are fine, I cannot figure it out what it could be. I replaced the EGR, and the Evap Can Seleniod. still it does the same thing? Anybody got any ideas to help me out?
the fuse blows when the car gets to operation temp i think its Closed loop?
Please Help!

I guess i can disconnect the fans and see if it will blow the fuse does this sound like a good idea to test out your idea?

******UPDATE*******
Ok so Got the wiring diagram from a good friend and found out that Fuse #6 in the Fuse box runs the Coolant fans, EVAP, EGR and O2's. So i chased all the wiring and found a couple spots where the wires were exposed so i fixed all that and i couldnt find any bad grounds. I also checked out the fuse box to make sure the wires were ok and they were. so i was pretty confident i fixed it. I put everything back together and installed a new 10 amp fuse and started the car. car ran fine until it hit full operating temp closed loop i believe and the fuse blew. I was so pissed off i didnt understand what was wrong.
So i figured hey the only thing i havent checked is the PCM. I had an extra PCM so i put it in and started her up and she ran fine with no issues so far i have driven it about 15 miles today.
The PCM was Bad!
