QUESTION: Yes for about a year, then I could not turn off the lights.

Answer
It IS highly possible that the headlamp relay is sintermittently sticking ON causing the module to over heat. You will need, If necessary, Electrical schematics and picture locations of the components within the system that is causing you problems of which can't be done on this website which only allows one picture.  I do not have a website so you will have to e-mail: onlineautohelp@msn.com in order to obtain the information.
