2000 Regal Climate Control External Sensor

My Climate Control external sensor readout is inaccurate at times. This past summer when it was over 100 degrees, at times it would read less than 60 and the air conditioning would not work. Last week it was reading -38 and the system would only put out full heating. I replaced the external probe and it didn't help the problem. Any suggestions? Thank you.

Hey tbaugh. I just was scanning some more and there is a similar problem described by Firebird3800. A recommendation was given by the moderator. Try his thread.

Take care good luck

Replace the sensor!
