I changed the radio on Saturday and last night i lost all dash gauges horn wipers and more it says no bus on dash I ran the soft code it say p1687. I put factory radio back in disconnected the battery for several hours and still the same I don' know what else to do

 

Probably burnt a fuse somewhere.

 

I checked all fuses not once but twice I found one blown it was to the radio amp I changed it and the gauges started working for about 2 min then the same thing again. So I checked the fuses again and they where all good

 

Test that same fuse with a meter, or test light..... I have had them 'look' good, but, in reality, they were not.
