Light my fire?

, IS for WRITTIN'S

I hope I can finally get another job done on my van myself...Im creeping up on 70 yrs old so my DIY life is about to come to an end.  My Van's AC selector knob is not clicking as it moves from Vents, Defrost, Upper, Lower Vents etc.   MY Van is officially 21 yrs old now...and that means more and more when I search for parts it will be listed as: 
Out of Stock..meaning no one has it.  I found some used ones on ebay $149.  WOW I won't pay that, cause I can hit the knob with my hand and make it work...annoying tho...I assume the contact points are worn down so not making contact so I had a back up plan to remove it and solder the contact to make it larger..

I have to order the complete 3 knob thing it has the fan speed control on it, the temp selector, and the Heat AC Vent selector.  So I can hopefully pull off only the part I need and stick it in there and save the rest for the future.   I do have to order the whole component just to get this one piece off it.  
I found one by doing a Used Salvage Parts search where Salvage yards list parts they have on, like a clearing house...So I emailed they have it and it's ready for purchase...$35 plus shipping...

So I asked how to go about getting it ordered and hopefully he will answer soon and I can get it AND it should be a simple fix...

So wish me luck.

My right hip joint is still out of whack.  Somedays I can barely walk...without pain meds I can't.  And then when I sit down it gets so stiff, like it will never bend again...Yeah I know it totally sucks. So many repairs I put on the back burner now my pilot light is going out!  Before you know it I will be Out of Stock!
