Thanks partner, I am not sure but I believe the cig lighter still works and if so what next. Thank you in advance. Kev

No need for apology my friend, I'm old school and still appreciate human help without pressing 1, thank you again I'll check that out. Kev
I apoligize, try checking with a test light the IPC/Hvac fuse in the Inst/panel fuse block left side of dash.
