The switch is easy to get to and take off, but have your son look and inspect the contacts and plugs going into this switch. I have seen the mail end of the plug, there is like 3-4 of them going into this switch, literally melt and turn brown, I have seen the pins corrode and just need cleaning, and I have seen the pins pulled out of the pigtails. So make sure your son inspects the switch and the 3- or 4 plugs going into the switch. Oh and welcome to the site.
