Chrysler Repair: Tachometer failed:95 Cirrus, chrysler cirrus, data bus

Question
The tach is not working on my 95 Chrysler Cirrus. Can you offer any suggestions?

Answer
Hi Roger,
On the '96 (and as that was the 2nd year of production I would believe also the '95) my manual shows that the speedo/tach/etc. of the cluster all get their position data from the digital data bus, a pair of twisted wires that come from the body computer. The engine rpm sensors are also used by the powertrain computer, so if the engine is running properly those too are OK. So if the data bus seems to be working for the rest of the cluster it pretty much leaves the tachometer itself or an internal crack in the cluster printed circuit to the tachometer as the fault cause. So I would remove the hood of the cluster and remove and inspect it for damage. See if there is any replaceable drive component on the tachometer proper (there was in the late 80's to mid-90's, before the data bus). If none, then you have to consider a new tachometer module.
There are several pages on how to remove the cluster and gauges in the manual. Let me know if you want to try it and I will xerox and postal mail them to you.
I wish I could offer something simple but that is how it looks to me.
