Answer
If you are fairly mechanically inclined and can perform simple tests with a volt/Ohm meter you can diagnose and fix all these problems yourself. However, You will need numerous pictures and directives to do the diagnostics and this website here only allows ONE picture. E-mail: onlineautohelp@msn.com
