1997 Dodge Caravan Just 2 lights blinking on cluster

I have searched the group and found what I thought was the solution for
my blinking light problem. However...I only have the AC Light and the
Recirculate light that blinks.

When I run the diagnostic as you all have suggested..it seems to
follow through and turn the lights off. However upon exit of the
diagnostic...the lights begin to blink again immediately. If I run the
car with the blower on for about 15 minutes...the lights will go out.
They will start again when I turn the car off and start it again.

Functions controlled by all push buttons work wether the lights are
blinking or not. The other lights do not work while the 2 are
blinking...but will work when the 2 quit blinking. The previous owner
stated that this problem began when water dripped on the passengar side
floor mat. I have determined that this "water" came from the
evaporator. Does any one have any insight or ideas ?????

You are failing the cooldown test.....either from poor A/C performance
or a failed (evaporator) fin temp sensor. If trouble started with water
from the evaporator into passenger compartment, indicating a plugged
drain, then the fin temp sensor is likely culprit. Does the A/C seem to
work normally?

 

If the engine is not at operating temp or your a/c is not putting out cold
air the test will fail everytime.
