Wires Melted to Speed Module
I have a 2004 Motorhome on a 2003 Ford F-53 Chasiss (5000 miles on it). When leaving for a trip the overdirve light started flashing. Contacted Ford who had it towed in. Ford told me that the wires to the speed module were melted. They could not find any reason for it happening.
Does someone know what could have caused this?
Should I report it to to NHTSA?
I an concerned as Ford told me since they couldn't find a cause it might happen again and to keep an eye on it. If something caused the wires to melt don't you think a fire would be next. This is a Motorhome we sleep in it.

melted wires
Dave
I believe its mounted on the transmission. They told me that it regulates the engine and trans speeds. The wires that were melted were part of the harness that pluged into the main engine compartment harness going to the transmission.
Sorry that I can't describe it better but when I crawled underneath it looks like they fixed some wires between the main harness plug and a box (module) on the drivers side of the transmission.

Does it look like they could have been near the exhaust? I can't imagine wires melting on a modern vehicle without it blowing a fuse or fusible link somewhere. And that is just a sensor, so the power requirements for it are very small.

No all the wires are on the drivers side and there is no heat sourse to have melted them. Ford seemed baffled. No fuse or fusible link blew.
I have been reading about the Ford recall due to fires caused by the curise controll. This recall only went up to 2002. Even so can this possibly be my problem

If that's the same recall I am familiar with, that was a pressure switch mounted on the master cylinder up on the firewall. Brake fluid would leak into the pressure switch contacts and cause a bad connection. And this switch was powered all time by the battery, so it would sit there and start frying till it caught on fire. I think it was designed to disengaged the cruise control when you tapped the brake pedal.
