As for fan speed and control. There are a set of sixteen horizontal pins and two alignment pins that connect the climate controls with the control circuit board. This board controls everything from the blower fan to the electric fan on the radiator (in order to maintain enough air across the condenser). These 16 pins fit very loosely into the back of the controls board. In the library section, someone drafted a pdf explaining how he fixed the problem of his blower controls randomly failing. The controls aren't hard to remove just follow the many instruction pages in the library or the YouTube. Also, you don't need special radio removal tools to get the radio out. Separate a cheap set of thin (as in width) tweezers and slide one half in each slot. Feel around until you get the tweezer under the tab(s) holding the radio. Reach out to me if you have problems. How to reach me? I don't know because I've never personal messaged anyone from here before.
