So my AC is not blowing very cold air anymore, and generally speaking, windows feel better at anything above about 85.
A while ago (2 years), I smelled a barnlike hay smell coming out when I turned on the heat. I thought it was leaves/acorns that found their way into the vents.
According to the dealership last year when I got it inspected for something else, it was the evaporator core leaking.
The first quote came in at $1375 for a full day's worth of work.
The second quote came in at $770.
The car is a 2000, with 120k on it. Is this something I can bandaid until the car finally dies, or better yet, fix myself without the need for special tools? Or should I pony up some cash and have the pros take care of it?
