348 a/c controller

So, You here things happen to others but never think they will happen to you! My a/c controller is freaking out, ya know fan on and off, etc. If I lightly tap on the controls on the dash it stops and starts. Also, as it warms up it tends to do it less. I tried most what I read as the cause. Cleaned the terminals with a soft brush and elctric circuit board cleaner. Cecked the pins. I even touched up one spot on the printed circuit. It was a little better but really un usable. Do I really continue to solder all the points or ??? What other choices do I have

Signed, not hot or cold

 

Where can I get the stabilant 22a? The only thing is, if I lightly tap on the panel while it is freaking out, it stops for a bit. So I know the problem is right there.
