2005 Chrysler Town & Country Ground Wire Locations Sign In

Make: Chrysler

Model: Town and Country

Year: 2005

Mileage: 190000

Engine: 3.8L V6 FWD


Ok so I have been experiencing flickering in all the electrical equipment in my beloved minivan for the past 8 months or so. This includes cabin lights, headlights, dashboard, internal button lighting, etc. Recently my radiator fans just decided to die and so far I have replaced both the relay and the coolant temperature sensor and neither have gotten the fans back up. I also made sure that the fans aren't seized and they spin freely. The only thing left to do is to fix the grounding issue in the van and replace the fans entirely. But I don't want to replace the fans until I have the grounding issue causing my electrical flickering to be fixed just in case that was the cause of the death of the fans. The problem is I can't find a picture or article ANYWHERE explaining where the grounding wires are on my van. I took a good long look under the hood and I don't see anything immediately visible that looks like a ground wire either. Any help on this subject is much appreciated, thanks. Extra points if you can upload a picture with the wire locations.

Sounds like you are making an awful lot of assumptions with no basis for fact.
Sure you could have a bad ground, among a bunch of other possibilities also.

You diagnostic system amounts to using a parts cannon and hoping for results.



It's time to start using a wiring diagram and systematically troubleshooting the circuits.

Ok so, being as I am new to mechanics and electrical (but I am learning =D)... I am assuming that the only actual ground point in this diagram is at G102 (at the bottom of the image)... and that's what I should check?

Ok so I checked the ground wire its definitely in there nice and snug, unless someone else here thinks otherwise. I tried to attach a photo as well but it didn't work, so I will paste a google photos link here instead:

Any suggestions are welcome at this point for my flickering. Im at a loss and tired of being out in the heat staring under the hood Frown

Pics are tricky to impossible here but did see that one. Yes it looks good but that doesn't count yet. Test that backwards with even a cheap incandescent test light power the pigtail with battery positive power and poke the lag bolt, wire eyelets and wires seen there shouldn't flicker when items are in use or it's no good. Body metal is usually ground if contiguous with all body metal minus any resistance. Grounding begins battery to engine blocks then block to body metal first. Then again item by item add grounding throughout a vehicle or funky things will happen. If nothing else you need to watch that it works.


You said you weren't a mechanic but this is as primal as it gets. No ground or weak the power to whatever anything can't return back to the battery will screw up. If there's more wrong or a problem happened check AFTER you know the failing item has at least the power sent and ground is available just has to be ruled out as nothing is behaving yet. Don't just go tossing parts find out if correct power even gets there both positive and negative or item will not work or worse cause another problem,

That diagram is for the cooling fan circuit so it has nothing to do with the light flickering. The circuit needs to be troubleshooted using that diagram to find out what the issue is with the fans. Once you resolve that you will know if it was related to the other issue or not.

I'd check the voltages at the fan relay. Make sure there is power from the fuse, ground, output and control at the connector without unplugging it. You might need a scan tool to command the fans or maybe turn the ac on briefly while the engine is running.
The one thing the lights flicking and fans not working that might have something common is the IPDM. That could be an area to focus on if you see you are missing power and or control to your relay. Voltage checks should lead you to the culprit. Better to test than guess.





Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.
