The car is a 2005 Chrysler Sebring Convertible - Touring model with a V6. Within the last week, a smell like maybe sulfur, has started when I turn the heater on but goes away after a few minutes. This is something new. The interior does not fog up - so far it is just the smell and the car heats up fine. I have been keeing an eye on the temp gauge and there has been no change there.

This car has been a good car so far with only one semi-major repair so far. But due to age and mileage I am not totally surprised that something would pop about now and this has been a harder winter than normal. I am just curious if this is about a $500 repair or should I expect to spend about a $1000.... I am very greatful for any information/advice that you are able to offer.

Thanks for your help and have a great day!!

A sulfur smell is usually associated with an exhaust system problem. Next time you smell it, stop and smell the exhaust at the tail pipe. If you smell it there, suspect an engine misfire or over-fueling problem. These conditions should be detected by the engine computer which will turn on the Check Engine light and set a related diagnostic fault code. The smell could be coming through the fresh air duct from outside the car.

Also look around the bottom right side of the dash. Worn brushes or tight bearings in the heater fan motor can lead to higher than normal current flow which can overheat wires. Hot wire insulation gives off an acrid, nose hair burning smell.

You've already noticed one clue, the smell goes away after a few minutes. Before you turn on the heater, try smelling under the hood right after starting the engine and a few minutes later to see if that's where the smell is originating from.
