[Sawitfirst]

Hopefully this is right place to ask this. My daily driver 99 xlt indtrument cluster hvac lights and taillights went out on me other day and for the life of me I cannot seem to find the problem. I’ve checked every fuse in the cab and under hood. Not sure what my next step is. I haven’t checked any relays bc not sure which to check my dome light is working when open doors and when roll the switch but I have no other light my radio has its lights but that’s it. Please help me ranger pro’s I’ve taken you alls knowledge many times and works everytime. Thanks

Could be the main switch+dimmer on the left end of dash has gone bad; controls all of those failed lamps.
Need a wiring diagram for your year+model; somebody in these forums can likely point you to that.
