Reilywalker97 Posted September 20, 2022 Report Share Posted September 20, 2022 (edited) Hello guys, I have a 2011 Dodge Journey Mainstreet AWD. Several months ago I loaded my car out to a roommate who had to work nights and on his way home the car went into limp mode and died. We flat towed it home and my boyfriend got to work trying to figure out what was going on. Initially we thought it was the battery or the battery temperature sensor again so we replaced both then realized it was the alternator. I didn't have the money right off the bat and after the laundry list of problems the car has given me we let it sit for a while. Approximately four months. Finally we replaced the alternator only to find that the touch screen for the radio as well as the climate controls did not work anymore, lights don't even come on. The dash cluster and buttons on the steering wheel do though. Then we realized one headlight, one high beam, one break light and two of my four blinkers also don't work. We checked fuses and all are fine. One mechanic said we need to flash the computer stating that due to it being DOA for a while it confused the computer and it was stuck essentially in limp mode. Another mechanic said he could flash it but that it could potentially be an issue of a power surge having fried the system. I don't want to waste more money. I've already paid 11k for the car alone not including everything that has been fixed on it. We've gone to YouTube and other forums and tried all the magic tricks with buttons and checked the fuse behind the radio itself. Nothing is working. Please help.

5rebel9 Posted September 20, 2022 Report Share Posted September 20, 2022 (edited) To get the vehicle "on the road to recovery" with the least time and aggravation and wasted money on parts that don't fix the issues.......Time to go to a proper shop or DEALER for a thorough computer scan of ALL computer systems and go from there.

2late4u Posted September 20, 2022 Report Share Posted September 20, 2022 (edited) you could try to do the hard reset to see if that would change anything if you havent already tried that,sounds like you guys are just been unloading the parts cannon on this without having it checked out properly..What was the problem and codes from going into limp mode? I dont believe a bad alt wouldn't put it into limp mode, after sitting so long was the battery properly checked to see if it was still good? after rereading your post is it just the electronics acting crazy? will it start up and run? also which engine does it have?

Reilywalker97 Posted September 20, 2022 Author Report Share Posted September 20, 2022 It's been to a mechanic after the alternator was replaced and it had the problems with the radio and heater controls, he said the computer needs flashed by a dodge dealership and that it was confused after sitting so long. When I set up an appointment with dodge and told them what the mechanic said the dodge mechanic's response was well it could be that or it could be that a power surge "fried some things". Said we could start with flashing the computer and if it's not that then it's "fried some things" but didn't specify as to what so I couldn't tell you guys. It runs and drives just fine, battery is fine. Alternator is now fine, we tested it before we replaced it and it was bad which is why we replaced it. But now it runs and drives just has these issues with the stereo and climate controls where they just won't turn on. We've looked at every tip and trick to reset the radio. It has no check engine light on and from what my roommate said it went into limp mode before it completely died and it's never come back out. So it didn't go into limp mode after. Mechanic said that because it went into limp mode and then sat till we could afford to replace the alternator that it confused the system or something and that's why it's stuck like this.

Reilywalker97 Posted September 20, 2022 Author Report Share Posted September 20, 2022 I do want to add that the car is still blowing hot air so the system works I just can't control it. The radio also works but only way we can control that is with the toggles on the back of the steering wheel since that entire control panel is not working. We also checked all the fuses and none of them were blown. Quote Link to comment Share on other sites More sharing options...
5rebel9 Posted September 20, 2022 Report Share Posted September 20, 2022 You even checked the fuses that are located in the INTERIOR FUSE PANEL located between the glove box and kick panel on the passengers side? YES there is a possibility that the heat/ventilation module and the radio module(that one also has the CD player in it) could have been electrically "fried" being we don't know exactly what happened to the car initially. These are also BODY CONTROL MODULE (interior functions) computer, and hooked up by small gage wiring to these parts. They can easily be "fried".

Reilywalker97 Posted September 20, 2022 Author Report Share Posted September 20, 2022 Yep, checked the fuses under the dash too along with the ones in the engine compartment. All I know is when he was driving it the radio cut out and the screen went off, headlights dimmed and then the car shut off and wouldn't start back up. After we changed the alternator the car came back on, runs fine, heater is stuck on since I can't control it and the radio plays music but same as the heater I cannot control it. We don't know at this point what is wrong. The mechanic that looked at it pulled the stereo off and checked all the wires and plugs there and said everything looked fine as well.

What did you do to fix it, if you ever got it fixed lol. I am dealing with the same issues and i have no idea what to do. I just got my car out of the shop for the transmission. Before it went it everything was working fine. When i got it back the radio and heat controls wont work. Like when i turn my car on the heat comes on but i cant turn it off or nothing. I cant use any of the controls for the heat. And same with the radio it will work with the buttons on the steering will but the touchscreen wont work for me!! If you have any tips please lmk girl!

LadyQ Posted September 17 Report Share Posted September 17 I have a 2014 journey AWD limited and had the same issue after returning home from a 9 hour trip. The day after returning home the battery light came on saying there was an issue with the power system and while driving everything went crazy. Dash board lit up like a christmas tree even wipers came on without me turning them on and then it died and wouldnt start again. Intitally thought it was the battery or battery sensor but turned out to be the alternator. I didnt let mine sit for too long. It was less than a week before i replaced the alternator. It started up just fine but its stuck in low battery mode. My menu on the dash doesnt list the options just shows arrows until you select one and then it will display what is should be under that heading. Screen is blank and nothing on the radio works. My climate control is stuck on A/C but only comes out the defrost so it fogs up the windshield constantly. I did have the radio set on bluetooth when it died so im not sure if that is why it doesnt work but im struggling to find a solution to this problem. Has anyone figured this out yet? Any tips would be appreciated cause winter is fast approaching and i have no way to defrost my windshield or turn on the heat in this car.

John/Horace Posted September 17 Report Share Posted September 17 (edited) I’m a little lost. So a shop changed the alternator and gave it back with all the dash lights on? Was it a new or remanufactured alternator, how old is the current battery, they often only last 3 ish years. These cars need a strong battery, weak one will make car elec do weird things. How many miles on car and which engine? Edited September 17 by John/Horace 2late4u 1 Quote Link to comment Share on other sites More sharing options...
Dean H Posted September 17 Report Share Posted September 17 (edited) 1) Battery saver mode = weak battery. Get battery auto technician tested. 2) Automotive shop to scan the system for codes. Parts store scan is probably a basic scan. Not enough for you. Edited September 17 by Dean H Quote Link to comment Share on other sites More sharing options...
