you need a new speed control resistor... this is something you will have to get from the dealer, but you should be able to replace it yourself - it is under the dash on the passenger side mounted near the bottom of the fan motor.. you will remove a couple of screws, and it will come out of the black casing it is mounted inside.

chk. to see if you got a heater resister, it should be somewhere in the visinty of the blower motor 2 screws hold it in the heater box and it will have 4 or 5 wires in a plug going to it. samething happend with my truck and thats what it was. i also found out sometimes that plug with the wires to the resister burn, if thats the case you will have to chg. that too.

usually a bad blower resistor is at fault...

You are correct about replacement it will fix it and be cheaper in the long run. The bearing thats bad is pressed on, witch will be a bear to get off, if you can get it off. Every one i have ever known that had this problem just put another compressor on and recharged the system, its the best and cheapest fix. As far as compressor its up to you, but i would go with remanufactured at least you get a warrenty, if you buy used thats what you get is used or maybe someone elses problem. You will have to recharge the system, but you can do that yourself with a recharge kit from Wal-Mart around $20.00. Besides if it still has the old R12 refrigerant you can upgrade it to the new 134. One thing you should do is have the old refrigerant sucked out someplace that can capture it because of environmental issues.
