Hey guys, I'm new to this site but was a member of an Explorer Forum for about 3 years so I am familiar with how these work. The Explorer was sent to the junker for the cash for clunkers program and I was awarded with my mom's 2004 Envoy.
I have already converted the front low beams and fog lights to HID (6000k lows and 5000k fogs). I have done a full interior LED conversion and changed out the bulbs in the reverse lights and license plate lights to LED. I am looking to take the next step with blinker bulbs and brake bulbs.
I am familiar with doing LED taillight bulbs because I changed them out on my old Explorer and used load resistors to get them to flash normally. I wanted to find an easier fix for this though rather than tapping into a bunch of wires.
I have taken some pics of the blinker relay. It is a GM 12450284 relay that is used on most GM trucks. It operates the blinkers on the truck and for the trailer lights (when using). I've included pics of where the relay is located and how to remove it. Use a flathead screwdriver to push the small tab down and slide the clips to the larger holes. It should slide out the whole thing. Then push back the grey clip to loosen the hold on the relay. You may need to use a flathead to pry out the relay too. Be careful not to damage it. Here are the pics and now for the good news.
I have found a solution to the relay. I have found a product online called named GM LM455. It is the same 10 pin relay except with the right load for LED bulbs or a mixture of LED and incandescent bulbs. I am ordering one and will see what the outcome is. Here is a pic.
