I have a 95 Z that has a huge electrical problem. Code reader indicated a coolant fan circuit issue along with EGR circuit, EVAP circuit, and reverse lockout circuit. The 10amp fan fuse blows when i turn the car on. The relays are good. I looked up in the shop manual and all these ciruits are tied into this one fuse. Any suggestions would be much appreciated

 

I suspect you have a short to ground in the wiring harness(es) leading to these sensors/fans causing the fuse to blow. Check all the wiring to look for something worn through shorting to the chassis. You can unplug all the the sensors/fans then turn the key on and see if the fuse blows. If it blows it confirms it's in the harness and not a shorted sensor.
