colbylamb2006 Posted December 14, 2009 Report Share Posted December 14, 2009 I have a problem. My car has 165,800 miles on it now and the heater is starting to mess up. I don't know if it's whether I run it anywhere from 80-90 degrees with either AC, AC/ECON, or no AC at all. But now it's hot when I'm driving and when I slow down to turn or completely stop at a light or intersection it is not hot any longer and as soon as I start driving again it goes hot or back warm again. It's so weird. I thought it was the thermostat?? Or I may be running the AC when it's not needed, but if I do that the windows fog up...Can anyone please tell me what is wrong with my car. Otherwise no problems with my millenia. Still running very strong! Quote Link to comment Share on other sites More sharing options...
///BHRpowered Posted December 14, 2009 Report Share Posted December 14, 2009 Why would you be running the A/C. Whenever I use my heat its usually on high, but sounds to me more like the fan is bad, OR you have a block in the heatercore somewhere. FYI, you should always be running it on econ/no ac Quote Link to comment Share on other sites More sharing options...
Goliat6288 Posted December 16, 2009 Report Share Posted December 16, 2009 bhr... for some reason when it rain here plain heat doesnt do the job. when i put it on 80 or 85 and not on A/C everything fogs up. 80 or 85 with AC everything is nice and clear. when it not raining not AC at 80 does the job. thats the only reason i would have ac on at in cold weather.

///BHRpowered Posted December 18, 2009 Report Share Posted December 18, 2009 Sounds to me like something is blocking your defrostor, or atleast a line somewhere Quote Link to comment Share on other sites More sharing options...

latinopikachu Posted January 25, 2010 Report Share Posted January 25, 2010 if you hit AUTO the ac comes on to remove humidity and condition the air, otherwise it gets all fogged Quote Link to comment Share on other sites More sharing options...
