Instrument cluster blows fuse every time.
I am having a problem with my 99 Dodge Caravan, 3.3l. A few days ago the cluster/gauges stopped working, they
had lights just no tack, spedo, fuel..etc... When driving the van home it was stuck in second gear. I replaced the fuse
for the cluster and it worked for a short while, long enough to go out to dinner...then it went out again. This time only
it started to blow the fuse everytime you turned the ignition on. I was also having a couple of problems with the IOD fuse
under the hood. Not sure if they are related? Anyways. Everytime I install a new fuse and try to turn the engine over it
will blow the guages fuse and I mean every single time...I have gone through 15 bucks worth of fuses.
I have tried many things, I heard of a bad ground pin on the cluster board...so I checked that and it was fine. I even
tried the replacing the fuse with the cluster unpluged and it still blew. Sounds to me like a short somewhere. Or is there
a different device controlling the voltage to this?
From looking at the electrical scematics it looks as if this circuit runs into the "Body Control Module" Would be the Red/White
wire. Looks as if there is a grounding point for this circuit as well somewhere with the ignition gound. Any suggestions, is
there a voltage regulator on this model? Is it possibly the PCM or BCM? Help...!!??

It says he did that already (in red). There's got to be something else on the IOD fuse causing a dead short. I'd suggest that he gets a wiring diagram to find all components that come off that fuse. $15 for fuses seems a bid much, that would be well over 30. I'd think that after $5 worth of fuses, maybe a resetable circuit breaker would have been a good investment as an aid to diagnosing the circuit.
