We have a 2000 19.  The ac blows fairly cold but not as cold as our 2013 13.  This week while traveling the blower has started acting up.  When we turn the power on the compressor kicks on but the blower doesn't budge.  When I take off the cover and give it a spin it'll work, but it won't start on it's own.  What should I do? I'm happy to replace parts but if an 18 year old ac is worth fixing vs replacing I don't know.
