I have a 2003 Dodge Caravan Sport 3.8 with a front and rear heat. The rear seems to be working fine.....they kids say they are warm. In the front though, on a cold day cruising at highway speeds it's difficult to stay warmm I noticed coming out of a rest stop with heavy acceleration to get back into traffic it will blow somewhat hot for a couple minutes.
Any thoughts.....It use to run me out of it with all the heat.
IT has 199k miles.

have you replaced any cooling system components recently? how old is the coolant? with the engine off but the key in the on position, when you move the temperature control can you hear an electric motor going?

Check coolant level.

In the rad. Sometimes the recovery bottle stays full with a leak in the system.

I would suggest doing a through flushing of the cooling system including the heater core. The heater core could be partially plugged. Also check the operation of the water valve.

Dude, you do realize this thread is nine months old, just about, right?
