Posted a week or so ago about the AC "on-off" button sticking in the on position in a 98 camry.
Someone suggested spraying some silicone lubricant into the button.
My only thought was how to get the lubricant into the needed spot without taking apart everything.
Came up with an idea. I have a farm and have a few different size hypo needles to "doctor" the stock. Have a couple of 25-ga needles for kittens and puppies.
Sprayed a small amount of electrical contact cleaner into a paper Dixie cup and drew it up with the hypo. The needle was small enough to fit between the AC button itself and the outer plastic frame.
Injected a small amount of cleaner in six locations all around the button, waited a few minutes and repeated.
Then waited a few more minutes, repeated the injection, only this time with silicone lube.
Pushed the button a few times and then, all of a sudden it started to work properly. That was Saturday. Still works fine.....
