I have a 2005 Dodge Grand Caravan, and the heater recently stopped working. It will sometimes work for about 5 minutes or so, but will then blow cold again. Fans are working fine. I also noticed that the engine temp gauge will max out every once in a while. If I turn on the blower for the interior heating system, it will bring the engine temp gauge down very quickly.
Are these two system interrelated? Is it possible that I just need a coolant system flush or does it sound more involved than that. I'd like to try the simple fix that I can do myself before taking it to a shop if possible.
Any advice is appreciated.
