So, it seems impossible to get the correct info on the 2005 model. Some say this model has no fuse or relays, and some say in different location.I been researching for a week every were.I even pull 3 more hazard switches from the junk yard. None worked so odds are it's not the switch. There is nothing else in my jeep that doesn't work, so it can't be a 2 for 1 issue.I did find some say that a relay can go out 50% meaning blinkers can still work when hazard don't.I dunno. So today I discovered that if u reach up directly behind the fuse box under the kick panel that I could feel some relays back there. They are literally plugged into the back of the fuse box for the opposite side. But u can't see how many or identify them.I almost pulled one out, but I was afraid I wouldn't get it back in the right spot. Nothing I found online to help me. Well anyway if u have a 05 and can't find a few relays, that's a place where you will find a few more.I know some models have some way up top of the fuses under the kick panel area. Like I said there are some on the back side, just enough room to get your hand behind there.I hope someone can help me get my hazard working.I need them for inspection sticker.I can't afford to send this to a dealership, and get charged thousands for this. Thank u all. Hope at least the rest of y'all know we're u can find some more missing relays. Wish I could tell which ones they are. Hoping one is the one I'm looking for maybe. Lol

The blinker flasher function for this vehicle is provided by the Front Control Module (FCM). Which is part of the IPM, (integrated power module) so chances are the IPM needs to be replaced which is common, but I would check the electrical connectors of corrosion which is common as well. Here are the blinker wiring diagrams so you can see how the system works and how to change out the IPM. It is easy to replace because it does not need to be programmed. Check out the images (below). Please let us know what happens.
