95 sable, no dash, head or parking lights

This is basically an info post. Had the situation where the headlights, dash lights and parking lights were all out with no blown fuses. Using the EVTM to troubleshoot led me to the headlight switch. I found the headlight switch connector on the wiring harness to be melted. I had to visit a wrecking yard to get the pigtail off another harness, but in the process went through several Taurus and Sables before I found one that was not melted. The headlight problem is fixed but I was wondering if this is a wide spread problem, seems to be with what I saw in the wrecknig yard. Just a heads up for anyone having this problem.
