Thanks for the response. How do I test the TCM? I can disconnect it again and test with a new fuse. I only tested with a meter and it indicated that the voltage across the fuse slot was 12+ volts. I took that to mean the short was still there. However, when I put the meter in ohms mode and test the side of the fuse slot to ground that goes to the TCM, it shows open, indicating no short.
