'93 90S for Sale w/o AC?

["Jon" <jwilliam@ns1.water.net>]

I don't know if my last message  got on but it was concerning a 1993 
90s with 73,000 mile on it.  It's going for $10,900 which I realize 
is a good price but when I was driving it the a/c cut out and the 
tach stopped working.  After stopping the car for a minute the 
salesman who went on the road test with me went and got the finance 
manager who came along and, of course, the a/c started blowing ice 
cold and the tach started spinning just the way it should.  

My question is, does anyone know what might have caused this to 
happen?  The a/c concerns me more than the tach.  Anyone have this 
problem?  I'd not like to go into debt for a car and have to make an 
$1100 repair before it gets 10 miles off the lot.
