See also the earlier 2009 question on Inst Clust for 1994 Continental. I have a good working solution for this aggravating problem that many 94 Continental instrument clusters have. Here is the chronology of what I did. Hopefully this will lead you to a good solution and keep you from wasting time and money as I initially did. In August of 2013 I installed the alternate instrument cluster that I discussed in the earlier 2009 question. Switching Instrument clusters is a lot of work and some money, even if you do it yourself. Plus, it didn't help! I was still getting those very annoying chimes. I am an automotive engineer and I knew that my oil pressure was just fine, and that this was just a false warning. Actually I started getting intermittent chime warnings from the 4 gauge indicators corresponding to the top 4 pins on the 14-pin connector (pins 1, 2, 7 and 8). The chimes were the annoyance, not the fluctuating false gauge readings, so I used the shop manual to find the wire from the instrument warning cluster to the chime module. I cut that single wire and soldered a 16-inch pigtail wire to each side. The other ends of the two pigtails I soldered to a simple on-off rocker switch available from any auto parts dealer. I cut an 11/16 inch hole in the long, narrow lower dash panel for this rocker switch to the left of the rear window defogger rocker switch. When this switch is toggled off, there are no instrument warning chimes. This does not affect any of the other chimes, such as key left in ignition, lights left on, seatbelt not connected, etc. This is a great solution if you want to keep and drive your old Continental like I do. The wire to look for under the dash near the steering column is a Tan wire with a Yellow stripe, and comes out of Pin #4 (from the left) of a 10-pin connector. It is the Chime Generator line from the Message Center to the Chime Module. I have had this toggle switch for a year and a half now, and almost never toggle it on. The Continental is a pleasure to drive again without those annoying instrument warning chimes. Do this instead of trying to replace your instrument cluster.
This is the simplest & easiest fix, to make your '94 Cont. drivable, without having to listen to incessant CHIMES beeping every five minutes, due to faulty sensors and electrical glitches from the junk message system. Go under the dash, on the right side of the steering column and remove the plug (10 wires) from the 'warning chime module.' There is a tan/yellow wire in that plug on pin #7--that is the "tone generator" wire. CUT IT.!!! Now, when all of those faulty inputs try to get to the warning chime module--they CAN'T! Problem solved--no more beeping. This does not disrupt the chime from sounding if you open the door with your keys in the ignition, or with the lights still on--it continues to protects you from THAT. Remember to watch your OWN coolant & oil levels--to make sure no REAL problems exist--and you're good to go!

i had the exact same problem with dcm and oil and this is a sure way to resolve it. disassemble the dash and get to the wires in the back of the gadges. disconnect and clean connections. i had the beeping six to ten times a day and ithis fix it.
