I had a similar problem with my '89 200.  I had the A/C recharged first as 
it had not been done before and sure enough it needed a gallon and a 
half!  I still had an intermittent, the problem went away for a week and a 
half and while sitting at idle with the A/C on when the better half went 
into the store for some ice, the A/C stop working again.  I replaced the 
multifuntion switch and so far so good.  I could tell by just looking at 
the sensor it needed to be replaced.  The boost is a bit stronger too!

$95 at the dealer sucks... especially when I saw the following on eBay a 
day after!
