Flasher Help please
 
Hi people, I have a 2008 H2 which I have upgraded the lights to LEDs and everything is looking good, apart from the flashers, I have the dreaded fast flash happening, on looking it seems there are two options, 1 add resistors to each LED (not keen on this solution as I don't like messing with factory wiring) option 2 fit a LED replay, I've ordered one and its due to arrive tomorrow, but i cannot find where the original relay is, to swap it out, can anyone take a photo of its location and either post here or PM me it.
Thanks in Advance

Check above the Fuse Block Under dash by driver kick panel...

Someone will correct me if I’m wrong but isn’t the flashing all done in the BCM? Therefore no flasher relay.

your only option is to add a resistor. You could try and add it internally in the new light. Did you buy new fixtures or just led bulbs?

Thanks for info, I was trying not to mess with wiring, and managed to buy "a LED relay" For a Hummer H2 but was from a Amazon search so it could be going back if Flashers are BCM controlled and will have to go resister route, you could be correct as relay arrived today and I can't find anything that even resembles it..

There are led bulbs with resistors built-in:>>> 3157 anti hyper flash

Yeah I wouldn’t think so. The reason it fast flashes is by design to let you know a light is out. Maybe you can make an extension harness somehow and put the resistor in that so you don’t have to cut the factory wiring.

2008 doesn't have the same relay as the older ones do. The only options are:
  1. Pay dealer reprogram BCM to eliminate fast-flash (probably like $150)
  2. Install some cheap relays. That's what I did on my 2008.

I have these, and they do NOT eliminate hyperflash. I complained to the eBay seller about their false advertising, and they offered me some $$ back, no questions asked. It's almost as if they know they're selling lies!

You bought from the wrong seller! Btw, when I do, I do not accept partial from the seller, I contact eBay and get ALL my $$$ back for items not as advertised! https://cimg7.ibsrv.net/gimg/www.hum...1e4d40498c.gif

No dealers here in UK, so i've decided to just keep Halogen bulbs in flashers for now, changed every thing else to LED apart from the shifter lights, can seem to see how to remove the Shifter bit, managed to remove the handle bit any ideas chaps ? Please Photo of the bit i need to get under to change bulbs TIA Eamonn
