Anyone had the dealer reflash their ECU and had 4WD issues?

After the reflash my 4Lo dash switch does nothing! No dash light,no beeping, nada!
Has anyone experienced anything similar?
When I took it back they said the reflash couldn't have caused it.
It worked perfectly before.
What next?
Any advice would be appreciated.

remove the climate controls and check all connections at the 4wd switch and any loose plugs.


did you recently install a new radio?
 
Dash has not been touched. But I'll check that to rule it out. Hopefully it's something simple.
