Before trying anything else go under the hood in the fuse and relay center and find the IOD fuse and pull for like 3 minutes then reinsert . This will reset the bcm and may help your symptoms . If not then the bcm may have flaked out on you , hopefully not as they are real pricey to replace. All the stuff you are talking about is controlled by the bcm.

 

Prob a BCM issue....Had the same problem...Get ready to cough up over $200 for a new one, and dont get the bright idea to go to the wrecking yard for a used one cause it wont work..Gotta be new, and SADLY factory installed so that the new BCM can be "Wed" into the system....It sucks but they got us by the short hairs on some of this stuff!!!! If you think that is fun....Upgrade to a model that has Contained Area Networking....A real bitch to work on electronically...

 

Welp...ok but, I've read of several who have gotten a junkyard BCM and fixed their issues. They do have to get the identicle part number BCM and they do have to take it to the dealer to have it programed to match their vans VIN number and mileage. Also there was something about if the van has the factory alarm system that could screw things up. Don't recall exactly. You can also get BCMs from companies that rebuild them and they will do the programing for you. They just need the VIN.

BOBC96 - Yes, disconnecting the battery will accomplish the same as pulling the IOD fuse. You don't have to disconnect it over night. Just 2-3 minutes.

 

New information...the damned turn signals don't work either. It sucks not having a fuel gauge. I disconnected the battery and will let it sit overnight. Hopefully that will accomplish the same thing as pulling the IOD fuse.

 

That is true enough...You can go that route as long as you go to the dealer for the install....It may be different for the older gen's....I know my 02 t&c had a BCM issue...I lost all dash lights and gauge function...I do remember you cant just go down and buy one used, slap it in. and go back to the street....I knew there was some issues that had to be taken care of with the VIN codes....

 

I had the same issue on my 02 GC eX. The ticket said that the entire fuse block had an issue but the svc tech said that the BCM and fuse block had issues. Luckily mine was right before the warranty ran out so I can't quote the price of the fix.

 

Disconnecting the battery overnight didn't do it. I think that I'm going this route:

$75 to test the unit, not much more to have it serviced.

 

Try the smack the dash trick before you spend the bucks. Might be the infamous bad solder joint on the instru cluster circuit board. Nothin to lose.

 

I've done more that that. I took out the cluster while the vehicle was on and wiggled the harness behind it to make sure that it was properly seated. Nothing happened. I'm fairly certain it's the BCM. My dealer said that the BCM was the cause of my rear windshield wiper not spraying, so it's probably getting worse.

If this company can fix a BCM, I'll post it. It seems like they could save several members of this forum a headache.

 

I R&R'd mine from our wrecking yard without a problem. Pulled 3 till I found one with the same Part Number. Swapped out the fuse box and all. was a lot easier that way.

 

I'm bringing back my old post. I had the BCM tested and its fine. Any other thoughts???

I might have to do what cAvEmAndrEw suggested and swap the fusebox and front control module.

 

You could also have a bad cluster. Take it to a competant shop to have it diagnosed.
