heating (or cold air) not working in 2005 Toyota Highlander

This is a potential quick and free fix if you have trouble with your Toyota Highlander's climate control... i am not very mechanically inclined, so this may be obvious for most but, apparently, it was not for the technicians who looked at my car and recommended a much more drastic and expensive fix... I hope it works for you and you can save some (well a lot!) of money...Note that of course, the same could be happening in summer with your air conditioning: if your car blows hot air instead, the same fix will hopefully apply... I usually worry about the heating but it is also equally annoying when it happens in summer with the air conditioning...and it is fixed can be the same way (hopefully :) ) Good Luck!
