One problem related to defogger has been reported for the 2009 Smart Fortwo Cabrio. The most recently reported issues are listed below.
Blower motor operating intermittently. Sometimes it will come on and sometimes it doesn't, no rhyme or reason to it. Heater and ac function properly, but without a forced air system. This becomes a major problem when the windows fog up during rainy or cold weather and there is no way to clear them. I have read of many of these complaints online even on the Smart car forum. Smart does not acknowledge any problem. Out of 20 or so cars in my life I have never seen an issue of this nature and it can create a hazard due to inability to see while driving.
