How do you remove the heat n defrost controls????

Finally got it fixed!!!.... I ended up removing the pass. side defrost tube from the top and the glove box liner. But those dang clips that hold the cable are a PITA for guys with big hands. Also, after being attached for 44yrs the clip only partially came up, but enough where I could slide the old cable out and slide the good cable through. Hopefully I'll never have to go through that again.
