93 was the last year that user diagnostics could be performed on the ECC. All later years have to be scanned by a Tech 2.
My 93 SSEi throws a code once a year for long-term freon loss, but actually doesn't have a problem. I simply clear it (like you can't), and go for another year.
My 95 is a different story. My airmix actuator is bad (it'* currently disconnect and a manual adjust handle is rednecked in). It flashes because of this, but works fine in other modes.
The point being that you could have a non-problem or a minor problem that you just haven't noticed yet. It monitors many functions. It could even be the solar radiation sensor or interior temp sensor gone haywire.

But there is some good news...
If you don't want to take it to a dealer or you don't have access to a scanner that is capable or reading and clearing the HVAC codes, then...
Any codes in the HVAC programmer memory are cleared AFTER 50 drive cycles without a reoccurance of the code.

Hopefully, the 40th will serve your daughter well...does this mean we will lose you from our little club? :(

I hope I hear an SSEi in Nicks future.

getting an SSEi - I am still looking for one. I am considering selling my Diesel truck and getting a newer SSEi Bonn. What is the last year they made them?

UPDATED 11-16-05
I left it powerless for 2 days - same problem Blinking still exists
I next cycled the ignition to ON then OFF, powering the accessories without starting the motor, 60 times, checked once again, same problem Blinking still exists
I next cycled the ignition to ON Starting the motor, and powering the accessories then OFF, 60 times, checked once again, same problem Blinking still exists
I then checked the outside temp probe once again while the motor was running, I moved the wire around, gently forced the connection from wire to probe. I went back into the running car to see if it was still blinking, checked once again, problem disappeared.
Turned the motor off and restart once again, same problem Blinking still exists.
I then checked the outside temp probe once again while the motor was running, I moved the wire around, gently forced the connection from wire to probe. I went back into the running car to see if it was still blinking, checked once again, problem disappeared.
I guess my next thing to do is check to see that the blinking is not going away on its own after a period of time and I am only fooling myself when I go out and fuss with the wire and probe. If it still persists after 3 or 4 minutes I will remove the probe, clean the connections on both the probe and wire, reattach them and test it once again........
Any other Ideas welcomed
Has anyone had a probe go bad on him or her?

After tanking on shipping to you for five days, it sure is.
"time will tell..."
Ayup.

I've found many items on my 95 had corrosion inside the connections. This prompted me to buy my first tube of dielectric grease. Been using it on every connection since. Been much happier also. Less headaches.
Makes one think that when a mechanic works on a Bonneville the first training they get is how to purchase dielectric grease.

Nick, according to the FSM, the blinking indicates the HVAC programmer has detected a fault and has a current or historical code. There are 7 items that will cause the programmer to capture a code and set the ECC display to blink.
1. External temp sensor fault
2. Internal temp sensor fault
3. Solar sensor fault
4. Air mix door fault
5. Heat/AC contol panel fault
6. Loss of "keep alive memory" in HVAC programmer
7. Loss of serial data
Hopefully, the quick fix on the external sensor you tried fixed the fault.
Again, 50 ignition cycles AFTER no fault is detected may be required. It says the ignition needs to be cycled to "ON", so starting the engine should not be required.

Keep in mind that RAP can mess with you. Cycle the ignition with the door open. (Retained accessory power)
