We have an 08 Dodge Grand Caravan and there is a wrench looking warning light that keeps coming on. The owner's manual says if this like comes on with the letter P then Park Assist needs servicing, but doesn't say anything about just the wrench itself. Do you know what this warning light would mean?

Reports say that this can be caused by cold solder connections in the centre instrument panel where the A/C controls are. Electrical system issue here manifests itself in instrument cluster. Fix is to remove 4 screws to access A/C stuff. Look for burnt or loose wiring / terminals on connectors in this area.. Re-solder or obtain used replacemnt terminal if needed, from junk yard. Mine is 1999 Grand Caravan. Intermittent failures then permanent with instrument cluster.

You can take it to your Jeep dealer and have the service department try to flash the computer. This may fix it. If not you will need to purchase a shift control module. They are about $ 590.00. This is a very common problem on the Jeep Cherokees and Grand Cherokees. Hopefully you are under warranty still. If you ignore this problem this is what will eventually happen: You will be driving down the road and your vehicle will not want to go over 15 mph and it will shift erratically. Do not wait to correct this problem or you will regret it. Yes it is a very expensive part, but a computer in itself that the vehicle needs to function correctly.
