Yeah that's what I'll be checking next.

No there is no other switches that I could find, the new dash switch that I installed had a 4 pin conception , and a 4 wire conector into the wiring harness. There is no sending unit on the difference either .the difference lock works but I can't get rid of the light or buzzer

I just bought a 01 cx613 I drove it from calgary too winnipeg with no issues but now I have the difference lock light and buzzer constantly on when the key is on .it doesn't matter if the truck is running or not. I took apart the actuator and cleaned it and also replaced the dash switch with a new one . Yue problem till exists . Does anybody have any ideas what too try next . Thanks
