Fog problem
i have a 2002 s40 1.9t almost 100k miles. I have always had a problem with it in the winter and colder months. It always fogs up. When i start my car up in the morning to get the ice off anf am fog ill leave it running for a few min with the defrost on high and hottest. I get back at my whole car is fogged up including the rear view mirror. after this it really never came off my entire car ride (about 40 min).... also i drove to the mountains the other week and my car started to defrost on the highway. i put the defrost on it helps but my car really never defrosted completely and i had to keep it running the entire time or it would fog up again. if i changed the dial from like 2 to 1.5 it would start to fog up. any1 have this probelm as well.
Thanks

RE: Fog problem
Are you 'recirculating' the heat or are you keeping the outside air on? Recirculating the heat will not rid the auto of the moisture but the cold outside air introduced into the heat will help. You can also keep your air conditioning on. Do the floor mats of your Volvo have a lot of water in them? You see, hot air in an auto with a lot of moisture in it will cause your glass to fog up in the winter.

RE: Fog problem
I would still double-check to see if the climate control is in "REC" mode. On most cars the REC has separate control, regardless of whether the A/C is on or not. However, I have never driven an S40 so I could be wrong.
Try going over the owner's manual for "REC" and "VENT(fresh outside air)" mode control functions. If the heater core is fine, then the only possibility left is the ventilation mode problem. If controlled electronically, either the climate control module or the damper motor (if so equipped) may be shot. If manually controlled, there may be a breakage somewherein the linkage/cable.
