Kid was playing around in car, using the turn signals. All of a sudden the left side (drivers side) flashers stopped working and the clicker started going fast after 4 slow clicks. Front turn signal, drivers side mirror, rear brake lights upper and lower not flashing now. Right turn signal works fine but the passenger mirror doesn't flash.
Recently put in a aftermarket radio and backup cam (spliced into the rear back up light) but everything was functioning fine for the last few days.

Opening the hood, I can hear the left clicker working but no lights flashing. Bulbs are new and just replaced thinking that was the problem.

lights all work when opening car with fob

Scratching my head as to what it could be.

Ok well after a few days of painstaking trouble shooting... I cleaned and reseated all the grounds. The power windows stopped working except for the right rear. The power locks stopped working save for the drivers door. Dome lights not working. Turn signals not working on left side and brake lights. Added a ground from the drivers side (on top of the braided wire) to the alternator... no dice.
Rechecked the fuses... and BAM! MBEC 60 amp box fuse. Changed and all problems fixed! Was about to go into the dealership.
 
glad to hear....

one thing for others to learn is check all the fuses properly (use ohm meter)when you have some weird electrical problems
