I just switched all the tail lights to LED (brake, flasher, reverse)

All is well except the flashers...fast-flashing.

I bought a new LED flasher module, but can't find the original to replace it. Every other GM or Jeep I've had was just under the steering wheel/dash...but I have yet to locate it.

Help? Help!

You cant change the flasher in the 07+, you have to have the BCM flashed.

Out of curiosity..... Does your cruise control still work and function properly with the LED brake lights???.... LOL

Depends on what LED bulbs you are running. I bought Can Bus LED bulbs specifically for the brake lights because with alot of LED bulbs it will cause the CC not to function correctly.

You can always run a resistor to trick the computer into thinking it has regular bulbs in it.... but the resistors get extremely hot and can melt things, so if you go this route make sure you mount them to metal and preferably under the truck away from everything.

I bought the bulbs at AutoZone (Sylvania/Zevo) but I didn't see anything on them regarding Can-Bus, so I imagine they are not. I've asked around and have gotten different solutions. The most common was the need for resistors...but I'm going to try to track down Can-Bus bulbs first before resorting to the hot resistor mess...

I think the turn signals will need resistors either way.

Well crap. What a shame... I guess that'll be another job for another day. Or I'll just end up doing the Escalade tail swap.
