Could you provide a part number for the part you replaced? Was this the original issue or was this an issue that began after replacing the part? Seat switch is plugged in? Fuse for the circuit is good? Seat switch normally runs steer motor for a few seconds then shuts off, does that run? Does the lift beep at you when you attempt to use the hydraulic levers? Does it travel? Apologies for so many questions trying to get an idea where to start.
