I know this is not a Cad question, but my 91 Olds 98 is very similar to some contemporary Cads, so I will ask you Cad folks. The old beast has the "auto temp control" heating/AC setup, which will not allow the blower to kick in on cold days until the car has been driven anywhere from 20 minutes to half an hour. The heat is there, but cant blow it out the defroster. Owners manual sez there may be "up to a 4-minute delay" when weather is cold. So, it seems that even a new one of these would not blow thru the defroster right away, which seems stupid. And, now, with years and lotsa miles on her, "4 min" have expanded. I bought her for a beater and cant sink lotsa $$s into this. Once the thing comes on, it works fine. It will come on more quickly in northern Ohio cold if I fire it up and let it idle for awhile, shut it off, do the same again, and then drive off. But that aint much of a solution. Any ideas? BTW, I do own a Cad, too, so am not a complete interloper. I tried the Olds Club site with no luck. Thanks for any ideas. Jim, in Galion, Oh.
