The first and second position fan quit a while back and have been using the number three, four and five positions to cool the interior of my car, now those positions stopped working and I can't use the A/C. Can anyone help me?
Inspect for burnt wiring connectors at the switch and the blower motor, replace all that are damaged and the switch as well.

I had the same problem and I replaced the temp sensor and it corrected the problem.
SOURCE: blower fan not working correctly
It is the blower motor resistor and is located under the glovebox behind the blower motor.
SOURCE: Ignition stuck in run position with keys in it.
If it has a automatic transmission make sure it's in park (try pushing the shifter while twisting the key). Try wiggling the steering wheel while twisting the key. If the car is parked for long periods of time the ignition cylinder could be sticking (try spraying WD-40 in around the key). I had a classic car and the key fell out while the engine was running. And when I turned it off I couldn't turn it again even with the key, I had to replace the lock cylinder.

Your Problem Can VERY WELL BE with the Temp Sensor, As It Is the First in This Electrucal Circut . it Waits for 210-230 Degree Engine temp and Gives that Sygnal to the ECM then ECM Grounds out the Cooling FAN RELAY To Turn ON the FANS and the Temp Sensor is Usualy THE #1 Culpret Closley in front of the RELAY.
There are 2 Sensors On this Vehicle The One You Replaced and One Located At Trans Side of
Engine Closer to Front of Vehicle At the Head ,Thereis a 2 wire Plug On it and This Sensor Goes to the ECT witch CONTROLS COOLING FAN RELAY. Hope this Helps and if you Need A Diagram For this It Must be Emailed as FixYa Does NOT Support Large Picture Files. My Email Add. Is MY

SOURCE: seems like the car is staying in "ACC" (accesory key position)
the ignition lock cylider gets jammed try messing with the shifter my alero has done the same thing to me. the ignition cylinders on these the grand-ams and about five other gm cars with the dash mounted ignition are very ****-poor and a new switch at the dealer is 175.00 and you have to have it fitted to your key as the new one comes without a key
Usually the first thing to inspect when the blower fan stops working is the fuses to see if any are blown. Locate the 10A cluster fuse or the 25A HVAC fuse in your car manual, and examine them to determine if they need replacing. The car owner's manual will tell you where to find the fuses that are connected to the heat and/or air conditioning. On the interior fuse panel of the car, a 30 amp fuse is labeled "Heater" or "HVAC."
