Driver seat adjustment not working

The driver seat adjustment on my Tuscany 45AT stopped working several weeks ago. Lucky for me it was in the right spot for me to drive.

Today I disconnected the switch terminal plug and checked for voltage on the two heavy gauge wires. No voltage present. I made the same check to the passenger seat wiring and measured 12 VDC on the same terminals.

I went to the relay/fuse compartment (driver side front compartment) and found the fuses for the cockpit seats. I swapped fuses and checked both seats. The passenger seat still worked, the driver seat was still non-functional.

The problem must be on the back of the fuse board (loose wire) or in the cable harness going through the floor to the driver seat base.

Has anyone else had this problem?

How did you solve it?

Seat comes with pigtails - short wires. During installation the connection is made to house wires between hole in floor and seat. In our case wires to short and rotating seat 180 degrees for use when parked eventually pulled the connection apart. Look for that connection

Driver seat adjustment not working - Loose wire connection in cable loop

Thanks for the guidance ...

I found a section of the cable underneath the seat that was wrapped in a velcro cover. I opened it up and discovered one of the two crimp connections had failed. I will buy new (better) connectors and repair it later tonight. I will try to attach a photograph for the benefit of any other RV'ers that might encounter this problem.
