Gordy, thanks for all the useful help. Much appreciated. The switch replacement was prompted by a missing rear and non operating dome light. I found replacement bulbs and a rear dome light in a salvage yard. Did the install and both were on full time no matter the position on the switch. I'm thinking, new switch. Did the swap, same result. For some reason both dome lights were still hot. After much head scratching I went back to the salvage yard and found two dome lights with on/off switches on them. A little fudging here and there and voila! dome lights when I need them. Dash lights work just fine. I'll make a go with the eBay tool and see what happens. Thanks again.
