Thanks everyone! I looked at the wiring diagram this morning, the switch portion is fine, I do have input signal going into the module but nothing came out from the module. While I am checking the left wire with a 12V test light, I discover something. It works when I tag a test light to the circuit. You are not gonna believe how I fix this, I wire a 12v light bulb parallel to the left turn signal input circuit, it works now! It could be a bad module but I don't really care as long as it is working. I check the security system as well, everything is cool.

 

Heres whats happening to me. When I turn on the left signal. The four ways go on , and the red key flashes. The right signal works fine. I also noticed when I hit the brakes the rear signal lights flash 3 times with the brake light, then the brake light works. help please. i also have a b1126 code if that helps
