I tried the auto climate diagnostic posted on the techinfo for a 93 98 ( pressing off and temp up @ same time ) , but it doesn't work. There'* definitely a code store in it as the temp would blink for more then 2 minutes, anyone know how to pull the codes out for it?

You have to hold the buttons for a few seconds on the Bonneville. If that doesn't work, try http://www.aircondition.com/wwwboard/index.htm

Thanx Fuddy-Duddy-Buddy

I will try that again this weekend.. I try holding it it down for only maybe 2 seconds or so.. will try longer.. I also posted on that link also.

The thing is that the off switch is also says off/auto on it.. so everytime I press it.. it either turns off or on and it didnt' look like a standard Bonnevile style Auto Climate, as it'* way smaller..
