I have a 93 Buick Regal with a 3800 motor, I was driving down the hwy at 80mph when the engine cut off & it had rained. I found the ECM fuse blown I replaced & tried to start again & it blow the fuse. Not long ago I replaced the harmonic balancer, did not see any problems with crank sensor. I got new fuse & pulled engine code & got code 69 for the A/C clutch circuit. I don't know how that would blow the ECM fuse. I feel like it should be something else. Has anyone every run into this & if so what did you find?
