These are almost same symptoms that I have when running a '96 MP computer
in my '97. With the '96 MP computer, I get the chimes, 3 lights on, odometer
flashing but ALL gauges are not functioning.
Most, if not all, the gauges/lights/chimes in the '97+ receive their input
signals from a bus which links to a Central Timer Module (similar to
a local computer on a network) which located to the right of the glove
box. The CTM, in turn, gets receives a combined input signal via the
bus from one of the pins in the PCM. The PCM receives input signals
from the various sensors (temp./oil pressure/speed/etc.).
My guess is that some of these pins in the connectors at the PCM or the
PCM pins, themselves, got wet. Remove the -ive cable at the battery and
try drying the connector/PCM pins out out with a hair blower, put on some
dielectric grease on the pins, hook up the connectors and battery cable to
see if your panel will now function. It's not likely that the CTM was
affected (but you never know). If this does not correct the panel problem,
the only thing I can suggest is to take it to the dealer.
Hope this helps.
