Your battery went dead sometime and it messed up the computer. Disconnect the ground for 5 or more minutes. Reconnect and it should work. Please see the related question below.
If the squeeling is under the hood it is probably the AC belt. If the defroster is on the AC is on. Just tighten the belt. If the squeeling is under the hood it is probably the AC belt. If the defroster is on the AC is on. Just tighten the belt.
What or why? either a wire harness has become disconnected, a fuse blown or you have an older model with vacuum lines to direct the flow of air and this system is failing. the defroster is the default setting for the direction of flow and with out power or any other force applied to direct the flow, this is where it stays. this is all the info i can give without more from you.

It started in the Late-Third or Early-Second Millennium B.C., the actual "blowing" of glass using a tube did not occur until sometime in the First century BC.
Turn the AC or the Defroster off.

Start and stall out, possibly. Not start at all, not likely.

Is is blowing hot air on the drivers side, or nothing at all? If it is blowing hot air even though you have the thermostat set on cold - it could be the heat actuator. It will occasionally do this after about 75000 miles or so. Mine started at 114000 miles and if you turn it off and turn it back on - it will start blowing cold again...$400 repair. Hope this helps.
I had one in a 1999 Sebring JXI. It would start flashing when the engine was hot and at idle. I removed the plug from the sensor and cleaned up the connections. It was good for about 6 months, but then started up again. I found that it was better to use 5-30 weight oil and now it only flashes when the oil is dirty.
