I was am in process of changing my brake switch on my 92 Lincoln Town car and noticed that the plastic that is on the wire terminal melted. Wondering why this happen, what I need to do next, and if I could put the new switch on without blowing the new switch. This is the second time in 2 yrs. I have had to replace the brake switch. First time for the melting of the terminal. Thanks in advance to anyone who can help me!
