RE: Temp Guage
There's a temperature sender for the gauge on the intake manifold right at the front (look behind and slightly to the side of the distributor). It has a single small stud on it and a single red/white wire with a 90 deg. plug going to it. The sensor body is brass in colour. These sensors fail all the time!
A simple test: disconnect the wire and jump it to a good ground with the ignition on. The gauge should rise right to the top of the hot zone. If it does, replace the sensor.
It simply unscrews out of the manifold.
When installing it, put a bit of pipe sealant on the threads and tighten it down a little more than snug. You don't want it to leak, but if you REALLY torque it down hard, you'll damage the sensing tip.

RE: Temp Guage
I talked to my parts guys today. '88 Town Cars had two possible senders:
For the electronic display clusters: part # SW2328
For regular analog gauges: part # SW1344A
Both senders are ~$12.00. No big deal.
There's still a possibility you may have an open circuit in the wire between the sender and the gauge, and a very small chance it's the temperature guage itself (that's pretty rare on Town Cars).
90% of the time it's the sender. That's the first place I'd look.
