You're going to need to pull the control panel, located above the ignition switch. Usually one or two screws on the bottom or sides. Careful, the top is usually held in place by a tab on the panel that goes behind the dash sheet metal. After the screws are out, pull the bottom of the control panel a little bit, then the panel downward a bit to release the tab for the dash. (I've seen people break that tab.)
Look for corrosion or gummy lubricate. A bit of PB Blaster or Kroil, allowed time to work, will free it. (Spray cans can get messy so I sometimes spray on a piece of scrap metal and pick it up with a cotton tipped swab to apply it.) It may take a day or three for the PB Blaster or Kroil, applied repeatedly, to free the slider.
Once it's free, clean with brake cleaner. Re-lubricate, preferably with white lithium grease, and reassemble.
Do NOT use electronic contact cleaner! That "attacks" plastic, causing it to disintegrate.
Go slow and don't force things.
If you get stumped, yell and post pictures.
Note: WD-40 really isn't a penetrating oil or a lubricant. It's meant to inhibit corrosion by displacing moisture. (WD-40 = Water Displacement, 40th formulation attempt.)
From the backside there are 2 speed nuts that hold the control panel to the face of it through the dash. The control can not be pulled out the front because it is bigger than the hole, only the face plate after 1 more of those speed nuts are removed. That is where I stopped and fought to get those push buttons back through the holes in the face plate.
I picked up a choke cable from Autozone for 8$ drilled a hole right along side of the control panel in the dash fed it through the rubber grommet that the original was in trimmed to length and attached it to the valve. Bring on the colder weather :)
Thanks for your insight on where I may find a manual.
