Lost left turn signal at 7-way on 04...

[steved]

OK, friend of mine has an 04 gasser 2500... its got the towing package, etc.



He has lost the left turn signal and brake light (same pin) on the 7-way receptacle. Now, I know the newer 06 use a computer to control/protect this that must be dealer reset, but the 03-05 use fuses correct? He says the fuses are fine under hood...



The thing is pretty much corrosion free (even compared to mine), so I doubt its a connector issue. Although I have heard the connector between the receptacle to the truck's wiring is a known problem...



Any other places to look??

I would check the connector to the plug and just start there and if there is no power there then I do believe there are relays and other fuses to check.

I have an 03 V10. The one signal doesn't

flash on the trailer harness. The 03 has two flashers soldered into the fuse block

under the hood which I believe are for the trailer lites. The flashers in this truck are not under the dash. I had to actually disconnect the wire harness from the block and break apart the block to find the relay flashers. I am getting a computer tech to solder two new ones in as I do not know which one is defective. Dodges fix is to replace the complete block for the fuses ($175. 00)

If your configuration is the same here is the relay # needed Tyco - VFMA-21F42-S01. I just received the relays have not done the fix yet. Hopefully this works.

Would this kill his brake light too?

I'm not sure about the brake light. I got the relay flashers replaced and tested the lights today. Everything works now like new. I replaced both flashers . Wasn't sure which one was defective. Only wanted to do the job once.

How hard was it to pull the PDS? I may attempt replacing the relay in his truck...



I also have another idea which involves splicing into the truck's wiring and powering relays installed in a box under the bumper)...
