tjc transport Posted December 16, 2022 Share Posted December 16, 2022 have you checked for power into and out of the switch? Quote when you are up to your armpits in alligators, it is hard to remember you only came in to drain the swamp.. Link to comment Share on other sites More sharing options...
Mackpro Posted December 18, 2022 Share Posted December 18, 2022 The new interior GR, AN and PI’s use a door control panel that is actually a ECM . You can actually flash out a fault code on the control panel . Quality was horrible on the first couple of years and I believe Mack changed supplier and quality improved. On one of our Anthem’s we changed the drivers side DCP 3 times . Lucky we have the extended chassis warranty on all our trucks. 1 Quote Link to comment Share on other sites More sharing options...

Mackpro Posted December 19, 2022 Share Posted December 19, 2022 I sent you an email . After looking at the wiring diagram it doesn’t show the power and relay . The Mack/Volvo diagrams are horrible as they don’t show the complete circuit on one page. I’ll do some more looking Quote Link to comment Share on other sites More sharing options...
