My temperature control buttons on my 1999 Legacy Outback are very sticky.  It looks like I have to take off the panel covering them.  I found a description of how to do this - take out screws and then "wiggle" off - but my upper panel won't wiggle off and I am afraid of breaking it.  Please help - this is one of the reasons my husband wants me to get a new car but mine is working just fine and has a lot of miles yet to go - I hope.
