After spending many hours banging my head against a wall, reading what seemed like endless forum's about climate control problems and getting half a dozen different answers to what seemed like the same problem... I have decided its a good idea to help the next guy out. So the two following .pdf files are how to diagnose your climate control problems with no special tools what-so-ever. All you need is a piece of paper and a pen. The first file you should run is the "scanning sensor values". This will first let you know if any of your sensors are bad which might be throwing off your system. If everything checks out there run the "fault memory" file. A word of advice on the directions on "step 1 and step 2" engaged means that the wheel is all the way locked on high or all the way locked on low not just somewhere in the red or blue zone. When I ran mine the first time I had a ridiculous amount of errors (since the car is 16 years old and apparently no one ever cleared them before) so I deleted them all, ran the car for 10 minutes then re-ran the test. I then had just 4 errors. When you go to delete errors you must do steps 1-5 first then do step 9. Also, before each code deletion you must press the "left auto" button before pressing the "right auto" button. Keep doing this until the display reads "E0 00". After you run these 2 files you will know exactly what is wrong with your climate control system without spending a penny.
