gearhead204 Posted October 5, 2015 Share Posted October 5, 2015 when you replaced the dash switch did you see a one or two wire pressure switch teed into the "work" line side of the switch? it sounds as if you have a faulty pressure sw.

Len Vernie Posted October 6, 2015 Author Share Posted October 6, 2015 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 Quote Link to comment https://www.bigmacktrucks.com/topic/42047-pdlo-light-and-buzzer-stays-on/#findComment-306486 Share on other sites More sharing options...
41chevy Posted October 7, 2015 Share Posted October 7, 2015 Could be as simple as a bad ground to the light or buzzer.
