Electrical problem

joshua1221 · June 5

installed a set of OEM mirrors that had puddles and power folding with the goal of adding the options to a switch panel to control since the truck did not come with the features.
after hooking everything up my head lights don not come on and interior lights are flashing along with hyper flash signal lights.
I took the mirrors off and installed the factory ones and no fix.
Disconnected battery and tried to rest the BCM with no luck.
Along with the interlock solenoid clicking when I press the brake to put in gear.
Truck runs and drives fine.

update your account to include the make/model/year/engine/trim level of your vehicle.

Then check all your fuses and that everything is plugged in around your doors.
