My van was running fine, I had the instrument cluster problem but just off and on would quit working and come back. I took it to the shop and had the air conditioner serviced and when they were through they could not get the van to start to get it out of the shop. We replaced the cluster board thinking maybe that was the link, but still won't crank. The dash lights and all the cluster board items come on and the fan will blow, checked battery etc and all ok, the shop wasn't sure they thought the power control module. I can't find this item on a parts list or where it is located on the car. Do you have any ideas?
I was having the same promblem for my 98 dodge grand caravan es...with the no stat promblem...i had the (bcm) replaced in it body control module...but that did not do no good either because it only got it started for a few days...now it's back at the shop and the last resort would be the wireing..because everything else is fine...starter,relays,battery,etc...hope this helps...any more questions email me at [email protected]

At the moment, your instrument cluster maybe faulty? Due the basic tests, try to be sure. Check for applicable trouble codes relating to instrument cluster--pcm--communication codes. Some of the national brand auto stores in this country may check codes for free, if there are any.
Check voltage and ground circuits for the instrument cluster. The sending units for gages are wired to pcm then the pcm sends serial data to instrument cluster telling instrument cluster what to do with gages. If you want to check gage sending units, that's ok.
If you have a scanner that can communicate with instrument cluster, you can get instrument cluster to do a self-test. The self-test, the instrument cluster will turn warning lamps on and off, sweep gages w/o outside data input. The instrument is considered good, if it passes that test, if not, the instrument cluster is considered faulty.
More then like it's the instrument cluster . .Plus you probably have no idea of how complex these are . Has microprocessor inside with logic programmed in . Taking it to a qualified repair shop an having it diagnosed would be your best bet . Hooking up factory scan tool to see if the instrument cluster will communicate with the tool , an checking for DTC'S - diagnostic trouble code's .Messing with thing's you have no clue about will only make it worst . YES , changing the PCM would need to be programmed ,dealer only .
First, replace the cam and crank sensors as they are so common and fairly cheap. If that doesn't do it then it could be the main connector on the back of the instrument cluster. There is a printed circuit board that the vehicle electronics comes into and the pins at that connector seem to have a problem with cracked solder joints. Remove the instrument cluster, disassemble it from the PC board and re-solder the connector pins. I've had to do quite a few of these. Next, it could be the fuel pump or fuel pump relay. I'd replace the relay as they are also cheap and may save you a lot of looking.
i dont see why they would diag the pcm for the rear wiper, power from fuse to switch to wiper!! no pcm in between this operation. I would have had this fixed in a hour. Have mechanic pay for the bill to get it running. It was running fine when you took it there and only the rear wiper didnt work and now you are out of a vehicle and a tow bill at a hourly dealer cost. Best of luck to you 300.00 later.
is a common problem with the voyager,caravans and Town & Countrys.
What the problem is is a cold soder in the interment cluster itself. The
problem area is where the plug comes from the van into the cluster. You
need to take the circuit board out of the cluster and reheat the soder
on the back side of the circuit board were the plug plugs into. This
will fix the cold soder permanitly I think its about 16 pin you have to
reheat with the soder gun. If you don't feel comfrotable doing that you
can just replace the interment cluster and it will be fine but if you
buy a used one make sure it was tested. Hope this help I have done
several of them.
Have you checked it with a scan tool to be sure it is actually getting the information? The instrument cluster do go out, meaning the ribbon on the back.I would check the connection, then turn to a way to determine if it is recieving a signal from ECM.
if you have replaced ther speedometer sending unit then your dash cluster is the problem chances are that the sending unit was only part of the problem. the cluster is static sensitive so have a mechanic replace it for you, if your not familiar with newer dash clusters, static electricity can short not part but the whole dash unit which is quite costly, so be sure to have a shop replace it, if your not up to the task
