Dodge Repair: Instrument panel dead, remote car starter, grand voyager

Question
I have a 98 Plymonth grand Voyager and the Instument panel will go completly dead for a few days the it works for several months.  It seems to happen after wet rainy weather.  Sometimes the panel will work again after you slam the top of the dash with your hand.  The other symtom is the check engine light is on during the outage and after the dash comes back on for a few days.  Then the check engine light will go off.  I am not sure if this may be the instrument panel or the computer.
thanks for the help.


Answer
Hi Scott,
I dont think I have ever come across your exact problem.
I checked for TSB's regarding your problem, and there were
none.
I would recommend removing the instrument panel (I.P), and
checking the connections.
I would also check the connections at the ignition switch.
It is possible that one of the ignition wires is not being fed when this problem occurs.  This could be caused by
a poor/broken connection, Worn ignition switch, or a remote car starter poorly installed or malfunctioning.

The next time this happens, grab a test light and remove panels for access to the wiring harness to the ignition switch. STAY AWAY FROM THE HARNESS FOR THE CLOCKSPRING AND AIRBAG. With the ignition on (in run) check for power at the dark blue wire, black&white wire, and the black&orange wire.
If one does not have power, then test it at the switch. If still no power, then replace the switch.  If the wire has no power, but has power at the switch then repair the wire.
