Weird smell

When my Accord is idling, occasinally I detect a smell coming from the vents. It smells a lot like burnt tires or rubber. But it only happens occasionally (3 times a year).

Any ideas?

I have detected this smell in 2 other 1998 Accords when test driving.

Thanks!

dont do doughnuts that much:eek:

j/k check to see if your blower motor is touching any type of plastic or rubber tubing under the dash, it may just be a loose heat shield or something.
