Chrysler Repair: 1993 New Yorker Electrical Problem, chrysler new yorker, voltage gauge


Question
In answer to your followup question my 1993 new yorker is the newer boxier looking car.    I just had a computer crash that wiped out my email from today so I am sorry to start this thread over again like this.

Thanks, George

Answer
Original question:
1993 Chrysler New Yorker Fifth Avenue.  Here's the problem.  First the Speedometer went to zero and at the same time the only little red indicator line on the gauges to work was the volt meter.  The Fuel, temp, and oil indicators had vanished.  Also, the display showing Fuel consumption, compass, and other info was blank.   Driving down the road, the speedometer miles per hour would come and go.  The Voltage red indicator line would come and go at different times than the speedometer coming and going.  None of the other red lines would work nor would the the "info" display come on. When you would first turn on the ignition, the gauges would all go through the "testing" sequence showing all the red lines and then disappear with the exception of the voltage gauge.  Then everything worked fine for a day or so.  Then, the starter would turn but the ignition would not fire.  At the same time as this problem, I noticed that the same three (fuel,oil,temp) red indicator lines went missing as well as the "info about milage, etc" display was blank.   After a while the car started fine and the guages and display also worked fine.  
Thank you much for any ideas..

Hi George,
I assume then that you have the C-body model (and that the 5th position of the VIN is a "C".
The intermittent loss of the gauge readings and other outputs is a problem between the body computer and digital dash/info center. The information to run all those is encoded digitally and carried on two wires that are twisted together. It may simply be a matter of a cold solder joint at the points where the pins for the socket at the cluster that are for those two wires is causing a temporary disconnect. If it starts up again, then you might try tapping/wrapping on the top of the cluster area of the dash and if that restored things that would be a good proof that was the cause.
The 'no start' may have a cause that was recorded in the engine computer as a fault code. Use the ignition key to get the codes:"on-off-on-off-on and leave on" doing that in 5 seconds or less elapsed time. Then watch the check engine light, which remains 'on', to see it begin to flash, pause, flash, etc. Count the number of flashes before each pause. Then repeat to be sure of having an accurate set of flash counts. Then group the counts in pairs in the order of appearance to form the 2-digit fault code numbers. The last number should be 55 which means 'end of readout'. Then either write back or go to www.allpar.com/fix/codes.html for a code list. If everything is alright now, and you have no relevant codes then we will have to await a return to get any where with the problem.
