I have an issue with the dashboard digital and analog indicators dropping completely out for a few seconds and then come back. Sometimes it's gone for abt 30 seconds, then I tap dash just above the radio and it all returns. I'm assuming a loose connector but not sure how to check it out.

 

I"m having a problem with the power sliding back window. It worked intermitently a few months ago. Now it doesn't work at all with the pwer switchn overhead driver's overhead console .

 

Need more info ... I've done a couple srw switches on 09-12's
