I am getting wierd things happening on a 2001 dodge caravan - all
I suspect grounding issues. Can anyone advise of the main ground
points on this vehicle?
- I guess cable from engine to body.
- I am aware of one in the rear tail lamp assembly (left rear I
Any others to check before I itemize the issues?
Also - does anyone know how difficult it is to remove the main fuse/
relay block near the battery in order to 'flip' it over and clean and
tia for your patience and assistance.
I found this that I am going to start with. It may be of use to
This is a tuffy. My Chrysler service manual from Detroit only shows
how to remove the dash, headlight switch etc. in ref. to a ground
location. It doesn't show exactly where the ground is or how to get to
it. The Body Control Module (over your left leg under dash) has a
junction block in front of it that is separate and may contain ground
points. The connectors for both should be cleaned and checked. The
connectors on the PCM that is located up against the driver side
fender behind the power distribution box should also be cleaned along
with both ends of the battery cables. Also the Instrument Panel "leg"
supports are grounds that apparently initiate in the printed circuit.
I doubt that this is a problem but who knows. They show four ground
points at the Instrument Panel "legs". As for the cowl you may have to
remove the glove box or pillar trim to get to it. Here is the ground
points inside the car as listed.
G200---Inst. Panel Center Support (4)
G300---Left Side Cowl
G301---Right Cowl Panel
G302---Left Rear Quarter Panel
G400---In Liftgate (rear door) This looks like a
grounding strip with several wires run to it)
Here is the ground locations elsewhere. You might also look under the
right rear tail light for a ground associated for a trailer wiring
G100---Under Battery Tray
G101---Left side of engine
G102---Under Battery Tray (listed twice?)
G103---Left Rear of Engine
I think Chrysler made a retro wiring harness repair kit for the engine
to alleviate a wiring problem. I was also told that there are grounds
close to the radiator but I have yet to locate them. Hope this helps!
The first thing to do is have the battery checked. If it is the original
just replace it, it is well past it's life cycle. When they get old they do
not filter all the electrical noise and that plays havoc with the
electronics in the vehicle. Cars today are mobile computers and cannot
withstand any electrical noise in the system.
It is a brand new battery. I hope to get my mitts on the vehicle this
weekend to take a peek. Problem is it is always in use.
Rear tail lights out, rear wiper out, sometimes the dash lights up and
will not start - funny thing is the latter only occurred after the
battery was changed...
Well - I had a chance to check things out for a bit this weekend. I
was preparing myself for the worst, but so far so good.....
- It turned out the rear tail lights was a relay issue. I swapped
relays and they function ok , but now the horn does not - so obviously
the relay. I'll get a new one tomorrow.
- The heater I think turned out to be low coolant level and associated
vapour locks. I filled it up, ran it with the cap off for a bit, and
it seemed ok to me. Time will tell. (shhesh women - now I know why she
is soo exasperated with me and the way I do laundry....) lol.
- The issue was that the dash lights would come on and it would not
start or even crank. She said if she wiggled the gear shift a bit it
would start. I redid the battery connections and found an 'iffy' power
+ take off connection, so cleaned and tightened and it seems to be ok,
but she'll have to drive it for a bit and see if it re-occurs.
- The rear wiper motor I am sure is a relay and a gummed motor. I ran
out of time to try to find the relay. I did not see it marked, so it
must be in conjunction with another one. I'll have to check that
further another day...
I have had a bit of an issue with the caravan since new - it seems ot
eat relays at the rate of several every few years it seems. Usually
swapping them fixes the problem and causes something else to go
haywire, so I have just been replacing them. When I was checking it
out, I examined the large fuse/relay panel under the hood. It appears
(but not sure on that one) to be secured by plastic snaps on on the
bottom somehow. I am afraid to mess to much lest I break them.
Has anyone ever had one of those fuse/relay panels out? I'd like to
examine the underneath for any so-so or corroded contacts.
thanks and regards.
I have seen this issue when some of the wires in the bundle that crossed from drivers door to body break. Take off the door panel and bull back the wires from both the door side and the body side to inspect for breakage
