My 99 LHS seems to have a heater problem. In the past 2 weeks it will not always heat up in the morning. We can set the temp at 75 and up with no response. It sometimes acts this way during the day as well.
Any ideas?
thanks dave B.

Bad thermostat? Was radiator fluid recently changed? Could be an air bubble was left in radiator.
My Concorde doesn't have the auto-temp controls, so I've not had this problem. But 300M's have the ATC system, and there are frequently posts on the 300M Club forums about the kind of problem you're having - almost always a simple matter of re-cal'ing the ATC - here's how:

Coolant level ok, nothing has been changed since 8 months ago when I replaced the raditator. My wife drives it most of the time, I drove it this morning and noticed that with the temp up at 75 and outside air
53, the controls on Auto, that the interior fan was trying to run at max. After awhile it started working and everything seemed to be normal.Glenn thanks for the info from you and Bill I will try what you both suggested. thank you dave B.
You're welcome. I think re-setting will fix it.
