Thank you very much "tdodge" for your response,
the car is a 95 Chrysler NewYorker with about 107k miles. I bought it
used 3/03 for $5500, from it's original Pennsylvania owner. I live in
NYC where driving conditions are generally lousy. The car has some
problems but mostly it looks good inside and out and was running very
strong until this overheating problem occurred.
I noticed the rad fan was not turning on and causing the engine to
overheat. I changed the "temperature switch" which regulates the rad fan
but the fan still (did not) click on. I'm driving the car with the
temperature switch disconnected to keep the rad fan "constantly"
running.
Now the car does not start up properly and it performs sluggishly.
You mentioned that the problem might be electrical and concerns the
"pcm". Any additional info would be greatly appreciated.
ty tdodge for your help,
and anyone else who might add anything.

hi its me again, tdodge. so if you disconnect the switch and the fan keep
on running then your switch circuit or wiring from the switch to the main
computer(pcm) to the relay and to the fan is all good because the computer
is able to process the signal when disconnecting the switch.
question, do you have good amount of heat coming
from the vent when heater is on? if not cooling system may have air lock
and requires bleeding
to release the air trapped in the system. also did you try replacing your
thermostat? i would try replacing the thermostat first before anything
else.definetely no problem with cooling fan system
