With all the MORE serious things I've had go wrong with this car, I almost feel guilty even worrying about it, BUT....

The passenger side heated mirror doesn't heat. The driver side one heats up OK and dries off the ice, snow, etc., just fine.

Best guesses on where the problem might lie ?



"Researchers have discovered that chocolate produces some of the same reactions in the brain as marijuana. The researchers also discovered other similarities between the two but can't remember what they are."

The heater element is probably defective in the mirror. Sometimes the connector that the wires plug into the back of the mirror get resistive also. Move the mirror to the outside all the way and you can see the electric connectors behind the mirror. You can gently pull on the mirror and it will pull out. You can use a Digital Multi-Meter and ohm the mirror element to verify the element is open. Most likely it is. A new mirror is cheap from Volvo, just replace it, it's fairly easy.
