Dodge Ram 1500 rear turn signals don't work

unclewally

I have a 2006 Dodge Ram 1500 2wd and recently started having flaky turn signal problems. They don't work in the rear. After doing much reading online the general consensus was 90% of the time problems with blinkers were due to a bad faulty multi-function switch. I bought one at O'Reily's for $68 and put it in yesterday. It made no difference. Everything else works fine (brake lights, flashers, etc.). Can anyone help me?

You may need a more methodical diagnosis process. I'd start by getting yourself an inexpensive test light and seeing if there is any voltage going to the bulb connectors back there. Do you have a tow package with connector for the trailer? If so, this might be interfering. I'd also check for bad grounds and of course, a bad or funky tail light fuse.

Here's what I have: You might check fuses 14, 15 and 16. There is no turn signal relay on this truck.

The Integrated Power Module (IPM) is a combination of the Power Distribution Center (PDC) (1) and the Front Control Module (FCM) (2). The PDC mates directly with the FCM to form the IPM. The PDC is a printed circuit board based module that contains fuses and relays, while the FCM contains the electronics controlling the IPM and other functions. The IPM is located in the engine compartment, next to the battery and connects directly to the battery positive via a stud located on top of the unit. The ground connection is via electrical connectors. The IPM provides the primary means of voltage distribution and protection for the entire vehicle.

The molded plastic IPM housing includes a base and cover. The IPM cover is easily opened or removed for service access by unscrewing the cover retaining nut and has a fuse and relay layout map integral to the inside surface of the cover. This IPM housing base and cover are secured in place via bolts to the left front fender support assembly.

Replaceable components of the IPM assembly are broken down into the following components:
The Power Distribution Center (PDC)
The IPM cover
The Front Control Module (FCM)
Complete IPM assembly that includes all three parts
All of the current from the battery and the generator output enters the integrated power module via a stud on the top of the module. The integrated power module cover is removed to access the fuses or relays. Internal connections of all of the power distribution center circuits is accomplished by a combination of bus bars and a printed circuit board.

Thank you for your help. Your answer was what I was afraid of. And yes, there is a connector for a tow package just under the dash with an empty socket, and a pigtail hanging in the rear. It would be a great help if you could tell me where the fuse is and also the relay for the turn signals. I've checked all of the "recommended places". I can't find a fuse block anywhere. Again, this is a 2006 Dodge Ram 1500, V-6, automatic, all pwr.

WOW, that's what I call an ANSWER! Thank you very much for the detailed information Mr. Shiftright. I had originally accessed the IPM, but the list under the cover did not show any entries for turn signal indicators. I'm going to go back out there and check it all out again. I never noticed any cover held in place with a retaining nut. Mine simply lifted up from the bottom and is hinged on the top. But in any case, you have provide me with a "ton" of information. Your responses indicate you have great depth of knowledge on the subject.
Thank you for your time and effort.

Not really Wally--I just have a good library. I'm no electronics expert by any stretch but I do encourage everyone to be methodical.
