"I have a 99 454 mpi and both
"I have a 99 454 mpi and both the trim tabs and the motor trim won't go up. The motor trim went down but won't come up. I replaced one 20 amp fuse that's for the motor trim pump. The pumps do not make any noise when i turn them on. Are there any other fuses I'm missing? Thanks, Gustav"
