I've just installed LED block off signal lights in place of the OEM mirrors. All the wires are connected properly. I have stock rear signal lights aswell. When i went to try the new LED lights out they wouldn't flash or come on at all. The rears aren't working either. When i hit the 4 ways all four flashers come on. I've also disconnected the front newly installed LED's to see if they were messing up the system but the rear lights still wouldn't flash or light up either. I'm really stumped here, i've also checked the fuse and used a multimeter to check for continuity and all seemed good. Wondering if anyone has encountered anything like this? Thinking it might be the relay ??
