I just "lost" all my turn signals and emergency flashers on my 03 SLT. They worked last night, parked it, came out this afternoon, and nothing. I checked the fuse, and it looked good, but put in a new one, and still no signals. I pulled the square "relay" under the hood, but cant tell if it's bad. I called Autozone, and the guy there says it might be the LCM. He says on some Dodges, the LCM controls the signals, emergency flashers, and sometimes the brake lights. I have brake lights, and the rest of the lights, just no signals. Any ideas, and where is the LCM located? I have the 4.7.
Thanks

 

what is an LCM? iv never heard that acronym used on these trucks.

since you have no flashers or turn signals i would lean toward it being the flasher relay (i thought it was in the fuse box in the dashboard, but i could be mistaken) its the only piece i can think of that is used for both functions.

 

LCM:Lighting Control Module. I have one coming in today, but don't know where it's located. I'll stop by the dealer today to find out. I'm taking the word of AutoZone this is what the problem is. If not, I'll return the Module.

 

In a Durango, the turn signals and hazard flashers are controlled by the 'Combination Flasher' and is located low on the far left of the dash. Use a small torx to pull the three screws at the rear of the lower dash panel (center one is right next to hood release). Then disconnect the clip for the parking brake (flip white clip downward, disco rod), then tilt the steering wheel up and pull the panel toward you while sitting in the driver seat. It might be easier to get that panel in/out by pulling the side kickpanel cover. It's only held in with one screw under the driver side sill step plate (3"x24" plastic sill plate, just pops out/up). [Fresh in my mind, had all that out yesterday to do radio work.]

 

Thanks, JeeperDon. I pulled the panel, replaced the LCM, and still no signals. I tried my wipers, and they are acting screwy too. I turned them on, then off, and they stopped in the middle of the windshield instead of going to the "Park" position. Could the switch be bad? I'm ready to order one if needed.

 

Don't throw money at it unless you know it will be fixed. Check you PMs.

 

OK, I need some help here. I just went to buy a new flasher for my Durango, and they are saying it's the same part I had for $69.99, that controls both the turn signals and hazard flashers. I saw somewhere the flasher is just a small cube. Can someone help me please? I need to get the signals fixed before Monday.
Thanks

 

Is this the flasher? I tried a new one and nothing happened.

This, according to AutoZone is the LCM; Lighting Control Module, and is also the turn signal and hazard flasher

 

If you haven't already, pull the neg battery cable and turn the key to start. See if that reset does anything. Also, watch this vid....

 

I pulled both terminals as they needed cleaning anyways, put them back on, and no signals. I watched the video a couple times but I can't find the flasher he says is behind the fuse panel. I'm hoping I don't have to take the dash panel out as well as the switch, but if need be, I will.
