1999 T&C LXI. The entire instrument cluster quit working today along with radio control buttons on back of steering wheel. Two months ago the instrument cluster lights quit working. The dealer service department cleaned the electrical plug connection on the back of the instument cluster and the lights worked again. What could this be? Autozone's code reader found code number P1698 but they said they didn't know what that meant. Can anyone identify possible solution?

After further searching on this topic I found the problem to be an open solder joint. Two hours of my time and zero money out of pocket problem fixed.
Thank You for all the info on this forum.

You would have been better off starting your own new thread but you're here so here we go. First this applies mainly to 3rd generation Chrysler Corp minivans (96-00) but can happen on newer vans. What model year is your van?

There is every chance you have a bad connection caused by cracked solder joints on the instrument cluster circuit board specifically where the connector is soldered to the circuit board. You'll find many posts on this subject in this and other forums. Here's a few links to more info on the subject:
http://www.obdii.com/ubb/Forum1/HTML/002928.html (Example of verified fix)
http://www.flickr.com/photos/landar/ (Procedure to get at the cluster and make the fix) Open "98 T&C dash removal" in right column then click "slideshow" at upper right.

Other possibilities:
> Melted connector on climate control panel (HVAC Panel)
> Poor connection or damaged wiring between PCM, TCM, BCM and instruments cluster
> Faulty BCM

All of these possible faults are associated with the CCD data bus. Your P1698 is a data bus fault. The data bus is used as a communications path by all of the electronic modules to communicate to and from each other. If a fault exists anywhere on the bus seemingly unrelated problems pop up. Judging by what I've read for the past 7 years the single most fail prone point in the system is the instrument cluster connection.
