I really hate to ask this question, but I honestly can not remember this fan setting acting like this.
OK. Here is what I've got. 1989 C68 climate control.
On the control head there are no blinking lights, all control functions seem to work fine, the "auto" mode works correctly, the "manual" mode works correctly. Fan speed can be adjusted, cold/warm can be adjusted.
The question I have: when in the manual mode and I have the fan speed set to any number, if ignition switch is turned off the fan speed defaults to the #1 speed(low).
Any 87-89 guys with C68 that can check theirs? I've only owned this car for 12 years, seems like I could remember this!

Thanks
Joel

As far as I recall, mine doesn't do that. But I have a problem sometimes (I've read it's a grounding issue) that occasionally when I restart the car it blows on 10 at 75* which is some sort of default setting.

I don't have my fsm in front of me right now but I can look later to see if that is referenced.

I've looked thru my FSM and just haven't
got lucky and found any info on this.
The more I think about this, it like a "memory" has been lost while in the manual mode.

Thanks

I replaced the Blower motor module 10/31/2010 with a
"Factory Air" name brand from Advance. So, considering my luck with these box store parts it's possible.
