OH yeah, i believe you're right. What is the number that is flashing for you? Give me a hint, I looked at it for like 2 months, i should remember this.

It'* been a while since it'* done it, but if I remember correctly it was just whatever temperatue I had set. I don't think it was a particular number that was always the same. I just recall I would start the car and it wouldn't blink right away, it would wait maybe 30 seconds and then instead of displaying the outside temperature, it would flash the set temperature. I think....

well, if thats the case then you need a scan tool. sorry, i really cant remember the painful details. :?

Check the procedure in TechInfo, and see if it will work on your car to retrieve the codes. They are probably still in there. The code is not displayed when it blinks; it is only displayed in diagnostic mode.

It just flashes the display instead of leaving it on solidly, that'* all, and after two minutes it stops blinking it again, until next time.

I can look in my '93 manual to see how you invoke the code readback, although I think it may be different for yours...

That'* the same procedure that is in Techinfo.

hitting "off" and "temp up" at the same time didn't do anything for my 95 ATC. guess it must be different than 93 or 94. Does it have to be blinking to get to that mode? Maybe since it wasn't blinking is why it didn't go into "Code Mode"

I dunno; I just went and looked at Item 22 in TechInfo, and it seems to specifically stop at 1994, nothing newer. He'* got a '95...

No not the procedure for his car... The one in your service manual matches the one in Techinfo.

The idea here is to see if this procedure works on a newer Bonny. Instead of pressing the two buttons together, try holding them down for 5 seconds together and see if that works. If it doesn't, then there is probably a different procedure for 95-99.

If no diagnostic codes are stored it should show "00."

I had a similar problem with my '94. To fix it I replaced the External Temperature sensor located in front of the radiator (~$15). Problem solved!
