turn signal and tail light problems
 

2006 EC300

Left blinkers work fine.
When I switch on the right side blinkers the rear one turns on and doesn't flash...If I unplug the rear one the front one comes on and doesn't flash

and my taillight doesn't work at all.


I've been over the wiring twice and all the connections look ok.....

anyone have any ideas on waht to check?
