2 seconds, that is a new speed record I am sure.Got my 2008 smart in 2014 and once winter hit I noticed the fan would chirp on setting 3. I discovered this thread and cleaned and lubed the fan. All was good until this summer.
The fan started to speed up and slow down. It did that for a few weeks. I cleaned it pretty much every day to get it to work. Eventually the fan quit working all together. Narrowed the problem down to the brushes. I ordered some off of ebay and soldered them in. All is well again. The old brushes were so short that the wire was not allowing them to go forward any further so they were making intermittent contact.
If it wasn't for this thread I would have had no idea on how to get at the blower motor. I can have it out of the car in 2 seconds now that I've done it so many times.
