Question about 2008 Dodge Grand Caravan

Dodge Grand Caravan electrical problem with dash malfunction lights and windshield wipers go on sporadically

Anyone have the fix for this issue? I have an 08 Grand Caravan that when I turn on sporadically and intermittently my windshield wipers started moving back and forth when they where off, all the dash indicator lights kept flashing off and on and the gauges kept going off or jumping back and forth. I can't open/close windows or lock/unlock doors from driver's side door controls and the car chime noise keeps going off like I just put in the key. This problem continues as long as the car is being operated and does not stop at all even when driving, It occurred about every other day for a few weeks but now is going on all the time and happens about every 10-40 seconds. I read that someone else was able to remove the drivers' side door fuse to get rid of the nuisance symptoms. I did this and it stopped the symptoms, but that isn't the final fix obviously. I hope that someone may know what the "fix is" for this issue as it seems to be similar to the Power Control Module (PCM) type of issues that Dodge has had in the past. I may need to get it replaced or perhaps reflashed. Not sure if that is the fix or if someone else has had this problem and had a solution that I can try before going that seemingly expensive route.

    Is the BCM Fault only corrected at the dealer or is there something I can do?

    Alas the BCM must be programmed with a dealer scan tool for your Vans unique accessory package and to enable the secuirty system, so you can't just plug one in, if you did you would need to have the van towed tot he dealer for a no start.

Hi, I also have a Dodge Grand Caravan 2008 with similar problems. The windshield wipers would come on for no reason, A/C would cut off and not come back on, none of the controls would work from the drivers side door panel, "dinging" noise would come on intermittent, headlights would flash like they had a mind of their own, dashboard would light up erracticly, etc.
After much searching on the internet, this seems to be not so uncommon. I brought it in to the dodge dealer where I purchased the vehicle and about $300 and 3 hours later the tech FINALLY found the problem! Most of the wiring from the door panel back to the body are "stranded" wires. These wires are made to be bent, time and time again, as the drivers door is the most used. But there is a control module that is also located inside the drivers door and it uses a "twisted pair" of really small gauge SOLID wire (that goes back to the onboard computer). If any of you out there have ever used Ethernet wire you know exactly what I am talking about. These are the same wires down to the color coding! Guess what happens when you bend a very small diameter wire over and over and over again? One of the small wires broke inside the rubber boot between the door and body. The tech told me what he found and spliced the wires with a 50 cent connector. The guy was honest and "kudos" to Salsbury Dodge in Baton Rouge. In my opinion this should have been covered under the warranty because it was clearly a defect in material and WORKMANSHIP (not to mention just a really DUMB idea from the designers at Dodge). This $300 fix lasted about 1 1/2 years and the problem came back. This time I fixed it myself with a new connector and a multimeter. Put the leads of the meter on both ends of the suspect wire and check for continuity. You will find that one of the twisted pair will have a break inside the insulation. Cut out the break and splice with an inline connector and wrap with a small amount of electrical tape. For my car the break was inside the rubber boot. If you are not comfortable with taking your door apart, bring it to an honest mechanic and he should have you in and out in about 3 hours (and hopefully a LOT less than 300 bucks). Hopes this helps.

This is due to a fualt in the BCM (body control module) not the PCM

I need to replace the windshield wiper blade


The 1998 Dodge Grand Caravan takes 28" wiper blades on both sides front and a 18" rear wiper. See related links below for more information. Since there are over 22 different wiper arm attachments, do not buy wipers just by length only - be sure to lookup exact wiper blade part numbers by vehicle make, model and year for the brand wiper you decide to purchase. This ensures correct length AND correct attachment.

My 2009 Grand Caravan's front windshield defrost isn't working


We have a 2008(same body) with the same issue. Just got back from the Dodge dealer and they said "they're all like like that" #@!& Not a good answer as we live in Syracuse NY home of 150inches of snow/season! Last year the right side wiper blade broke off because it kept getting hooked on the ice in that corner of the windshield. Chrysler should offer a fix of some kind because it effects the visibility of the entire windshield and is dangerous!!! The dealer said the other vents (set of 3 squarish ones) are actually for speakers on some models but they are in a lower/better position to heat the bottom of the windsheild and look like they should be able to have warm air run through them.
I think I'm going to double face tape a small strip of black plastic above the current vents to deflect some of the warm air to the lower edge of the windshield.
If anyone else has a better fix please post.
thanks,
Freexing in Syracuse!

The windshield wipers are stuck vertically and now


This sounds like the wiper motor has failed. You can pick one up at the local parts store. If not mechnically savvy, I would recommend taking to shop for working in tight areas that these can be. But, otherwise, the motor is on the fire wall, unplug, remove screws(4), exchange with new, and reassemble as removed. I hope this helps.

I have a 1997 Dodge grand caravan. Wipers go on with switch off


It's the body control module. I had the same thing happen with my caravan. It eventually evolved into the following problems no interior lights or chimes, no remote mirrors, dash lights and instrumentation goes out and ABS light comes on, no lighted vanity mirrors, blinking recirc & a/c buttons, no high beams. THe dealer said a BCM would be $700.00 with exchange otherwise w/o exchange 1200. I found one online - ebay. BE CAREFUl...if you don't have security on your vehicle DO NOT buy a unit that has the security feature..your vehicle will not run if you install this. match the part number off of your unit but also match the features.
