I finally figured out the problem with people out there with the flashing ECC outdoor display and screwing up the heat/air not working after diconnecting the battery. After talking to a couple of GM mechanics and reading posts from this site I solved my problem and it was so easy I'm kicking myself. If you have the same problem I had to do the following,

thumbup21. Locate your outdoor temp sensor (open hood and look down in front center of the radiator)

2. Disconnect the wire from the sensor

3. start the car (no outdoor temp) turn the ECC on the inside temp flashed as it did for me before.

4. turn the car off after around 3-5 min.

5. Reconnect the temp sensor and start the car and GOOD GOD no flashing light and the heat and air worked as it should.

after I did this my ECC works fine I drove the car 5 times shuting it off and restarting as I went and its fixed, no taking the dash apart or the glove box either or dealer repair cost. If this works for you please post a reply. Why GM could not figure this out is beyond me or there doing the same thing in the shop and charging $$$ to do a simple job. Good luck.




WOW this help me out alot >>> thanks now i got HEAT .....thumbup2

Mine continued to flash,,,,,Could it be that the sensor is bad??????
Wouldnt it throw a code, or is that part not read by the hook up under the steering wheel?

Would any of this have to do with my AC not working & my fans not kicking in without the jumper switch I added? Also, just to make sure, the sensor you speak of unplugging is basically on the radiator at the middle bottom, not the sensor under the thermostat housing, right?

Help!!!! I started having the same problem this morning. rolling along and AC is working fine, then messed with the controls to get the defrost on and now the readout is flashing for a few minutes and the AC isn't on. The snowflake by the temp is gone now to. I can set the temp to 60 degrees, but the AC doesn't come on. I hit a few buttons pretty fast, not sure if that had anything to do with it or what. Not sure how to test or fix. Need some expert advise/guidance please.
