I am looking at a 2004 PT Cruiser that headlights and running lights, plus dash lights have stopped working. All the fuses check good. There is power to the lighting fuse. Multi function switch was changed but no results. I do not see any lighting relay ? Anyone have any suggestions as what to look for ?

Thank you,
Mark

Welcome to Allpar.There is a 25 amp fuse #1 in the interior dash fuse block (not in the fuse/relay box under the hood) that supplies the multifunction switch through a Lt Bu/Or wire. You should have battery power at this wire at all times.
The headlamp relay is also on the same fuse block in the dash.
