Whenever I use the Heat or a/c i get a strong exhaust smell...im thinking either exhaust leak or maybe some vaccume lines are hooked up wrong. Does anyone have any clues? This is my first volvo and it has the usual problems with the heated driver seat and power seat no working but i cannot stand this exhaust smell. I would also like to add that i luv this site. Any clues on the smell would be appreciated.

I have the same problem. On mine one of the hoses that comes off the oil seperator is broken. I just ordered a new hose yesterday.

If a vacuum line was hooked up wrong you would have other problems than a stinky heater. Fresh air isn't supposed to come from the engine bay. Open the hood and check for leaves, pine needles, etc covering your intake vent between the wipers. At the same time check the engine for leaks - oil cap, dip stick, manifold breather tube, flame trap clogged. If your exhaust leaks it would be pretty noisy.

yes i dont believe it is an exhaust leak because it is quiet. I have talked to a volvo mechanic and he said to look under the cowl where the wiper arms are and check for blockage..like you have suggested. Thanks alot i will see if i can fix it now
