Intermittent electrical connections are NOT limited to Chrysler products
I agree 100% with Mex regarding the Deoxit stuff we always have several cans / bottles of it in the shop. The best stuff I have ever come across. Electrical connections are getting to be more of an issue with all the LED's and other very low current consumption devices.

Maybe I missed it - What year is your vehicle?
Have you tried a factory scan tool?
I have the DRBIII PCI Chrysler Buss based scan tool for my Jeeps TJ and WJ sure makes trouble shooting the kind of issues you seam to have much easier.
