My Outside Temp Indicator went on the fritz about 4 weeks ago. I saw this thread on the Site and finally went to get the Thermistor that Barrie spec'd out (Radio Shack doesn't carry them. BTW). On the way back home, the gauge started to work, and cycled from -36F to +136F twice, and then quit showing anything again. Inspection of the existing sensor shows no visible problems. However, the bracket looks like the took a rock hit. Maybe the shock killed the sensor.
Barrie, if you're out there, any thoughts? Also, is there a retail source for the thermistor?
