This is a mixed bag of problems
Installed Kenwood Marine unit following info here
Have lost the rear window defroster, third brake light and trunk lights
Can't figure how replacing radio would effect this.
Any ideas appreciated
Thanks

 

You made no mention of checking for blown fuses, repair manual available here on the forum has complete wiring diagram, use the search bar, good luck

 

Sorry
Did that

 

You may have accidentally unplug something bumped it with your hand any number of things I would send a p.m. To Ala-xfire he's pretty good at that stuff.

 

Thanks
Strange that those three separate items would go at the same time.

 

Where do those 3 things ground? A common point?
