The radio button on the steering wheel (the one with 1-6 on it) sticks in hot weather. It will not allow you to change stations, any ideas?

 

Well after further discussion with the wife, she says the button doesn't actually stick. It just does not move the radio from one channel to the another when it is pushed. She only notices this when the weather is hot, yesterday it did not work at all during her ride from work. Used a can of air this morning trying to remove any debris that may be lodged behind it, hopefully that will do the trick.
