All dash gauges, speedo and PRNDL are inop.
Electrical connectors, fuses and relays under dash and under hood have been checked. Dash Cluster has
been replaced. Body computer under dash electrical
connectors have been checked.
On occasion the cluster will come on at start up and
operate for a short time or possibly all day, with 3-4
restarts. Most of the time cluster is in-op 90 % of
the time. Could this be a corroded ground connection?

Any help you provide would be greatly appreciated.
I was a certified auto technician years ago and I am currently on disability.

Hello;

Thanks for your response,

As to your Questions.
Yes this is a Grand Caravan
Turn signal indicators do work when dash is in-op
Trip info and odometer and PRNDL are digital and are
blank, in-op when dash is not operating. 604 OD Trans

This AM morning, Dash is operating on first attempt.

I did remove left and right kick panels and dash
components to gain access to cluster.
I have not found any ground connection wires on
either side from sill plate to lower dash.( Grd. Location? )
Do I need to check terminal #7 and #13 with cluster attached or just at plug with cluster removed?

Thank You
Lee Babcock

Hello;

Cluster removed,
Checked cluster plug at pin #7 and #13
Both are complete circuit to ground showing 12-50 ohm
that is with key on and key off.

As long as dash is working no test will tell what is wrong. When it is not working check for voltage on term. #2 Pink wire, term. # 6 Orange and term. #10 blue/white wire. Grounds are good.

I rechecked #6 terminal at cluster with key on, 0 volts.
I installed the original cluster. Cluster still in-op
Is the body computer located behind the fuse panel, lower left dash?
If so, Where do I find #2 term ( there are 2 wiring plugs ) and standing on
My head under the dash with a bad back is, well its painful.
While I was poking around, checking fuses. I checked under the hood
Fuses and breakers. I removed the IOD, 10 amp fuse and EBL, 40 amp
Max fuse, now cluster is working again. What does the EBL Fuse supply?
Where does the BCM get its + voltage?

Thanks

BCM gets power from ignition and fuse #28 in Power Dist. Center underhood. BCM at junction box left side. Connector is E2 Orange wire 14 gague CHRY shows connector going into box #8 but at BCM it is #2. Don't think a fuse is going to help BCM must supply voltage if it was a fuse dash would be out all the time. Two fuses mentioned have nothing to do with BCM

Hello Docfixit;

Had errands to run Monday. But as of Tuesday AM,
Dash is still operating. Maybe I should leave it alone
until it goes out again.
Only question at this point is, what does EBL stand for?
That's the 40 Amp fuse in Power Dist Center.
Where can I access service manuals online?

Thanks Again
