'95 LHS 166,000 miles, Auto air, AC does not work.?

i own a repair shop ,and there's no way any one on here can answer that one correctly,you first need to get it diagnosed to see what all is wrong with it.if i was that good at knowing things i wouldn't be here answering questions,really though it could be anything wrong with it,air conditioning has to be done right or it wont last very long,good luck i hope this helps.

could be as simple as A/C needing recharging could need a new A/C compressor need to get it diagnosed by a certified mechanic with his accreditation in heating/cooling

Sounds like you are about to get ripped off. hahaha It might be that you need freon in your vehicle. Did you know you can BUY an A/C book and fix it yourself. What it is you can not put freon FOR MONEY on someone else's vehicle. But you can work on yours. The money for the book, gauges, vacuum and freon will run near $400, depending on how good the gauges and vacuum pump you get. The better vacuum pumps are faster but then money wise what is an extra 20 minutes. Then next year if you need freon you can do it yourself. This is something I did. I did not want to pay the $500 to FIX my unit. I was able to diagnose the problem and recharge it. The only problem I had was one during the summer. The frigging frostbite. hahha If not, take it to some shops for an estimate. A place like Pep Boys charges $30-$50 to check your A/C out. Even if you get a NEW unit, if you do not have freon you will still get hot air. But sounds like you need freon.

been working in a chrysler dealer for over 10 years 99.9% its the evaporator.need to diagnose veh.good luck $$$.
