Dodge Repair Questions? Ask a Mechanic for Answers ASAP
Hello and welcome! My name is ***** ***** I can assist you with your question. When did this brake light issue start to happen? Was it after the heater core replacement?
Would it be possible to get your VIN?
Thank you for that information. One minute while I pull up your vehicle.
Ok, this problem is caused by a bad integrated power distribution module, CHMSL (even though it is working) or a bad left/right tail lamp assembly. Basically, you will need to run some tests in order to see which component has gone bad. Let me explain...
The CHMSL needs to be working with the proper bulb for the instrument cluster to see the correct input from the brake switch.
You could disconnect the tail lamp assemblies and check to see if the brake light circuits are not working/getting power (using a test light or a voltmeter). If so, then one of the tail lamp assemblies is bad causing this condition.
By checking/replacing the CHMSL and then verifying that the brake light circuits going to the tail light bulbs are not working correctly, then I would suspect a bad integrated power distribution module under the hood.
That would be a last resort. I have a feeling you will find something sooner (and much more simpler) once you run these tests I have provided.
That is the Center High Mounted Stop Lamp

It has been a pleasure! Please let me know if you have any further questions!
Right, I understand.
I am just telling you how the system works. It is possible that even if the CHMSL is working ok, this can still affect the other brake lights.
It is not hard to remove and replace. However, it may need to be configured using a factory scan tool once it is installed. So you can replace it (if needed) and then have someone configure it.. or just have the dealership install it and configure it once it is installed. Either way, as long as it is installed and configured correctly..
You are most welcome!

Hello and sorry for the delay! I could be either. However, I was talking about the intagrated power module. You might want to replace both of them at the same time just to be on the safe side.
It's Amedee from just answer. I am just checking in to see how things turned out and if you need further assistance. Please let me know.
Sounds good! Thanks for the heads up!
Hello! Can you send me your VIN so I can do some digging for you?
Hello and sorry for the delay! Thank you for sending the VIN (again). Lets run this test.
Remove the fuse for the brake lights from the Integrated Power Module. Use a jumper wire to ground the White/Tan wire at the brake switch. If the rear brake lights go out, repair the Center High Mounted Stop Light (CHMSL).
Here is a wiring diagram.
Hello and sorry for the delay! Can you tell me how you did the test and what were the results?
Hello and sorry for the delay! Did you do this with the connector connected or disconnected from the brake switch? Because this will make a difference.
