Hey guys need a lifeline just replaced my turn signal switch on a 04 suburban, was the factory switch, so still having the same problem, turn signal on for the passenger side and tries to blink but doesn’t the driver side works perfect. Any suggestions?

I had this exact same issue. My passenger side turn signal would stay dimly light, and then blink fast when engaged like a bulb was out. Driver side perfectly fine. Check the wiring on the front passenger turn signal harnesses. If there’s a wire somewhere that’s losing its coating, it’ll short out and cause this exact issue.

I read somewhere were it could be the turn signal flasher. Its a combination flasher, I have not ever seen anything like it. I sold flashers back in the day when I worked in parts, but it is definitely different. I order part number LM487 off of amazon for 54.00 autozone wanted 75.00. Hoping it will fix it. I will repost if it does.

So, still not working correctly?
