How Do You Remove the Knobs from Heater Panel? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

NoNeck · 05-30-2012, 03:32 PM

I am replacing a missing lower heat control arm on a '70 GMC. I have a replacement arm with the little chrome knob, but can't figure out how the knob comes off the arm. Does it just pull off? I don't want to break my replacement arm if I am missing something.

I can't remove the replacement arm from the old panel with the knob on.

Thanks,

NoNeck

Yes, they just pull off. They can be tough to get off. I don't have any secret chants or VooDoo spells to make it easy, but if you can get something behind them and pry a little bit they should come off. Just move the lever to the off position and put some kind of padding on the face of the panel to protect it.

I use a pair of needle nose pliers and close the jaws gently up to the lever so that the knob is touching the needle nose. Once the pliers are in place I use a small hammer against the needle nose pliers to drive the knob off.

It works well and the knob is not damaged. A small thin open end wrench would probably work also.
