Is it possible you might have installed the thermostat upside down? How long was it hot? You might have burned your engine up. Check compression, each cylinder should be over 100 at least, and around 130 at best.

1. Have the SRS fault code retrieve
Do-it-yourself,
2. Remove the airbag fuse wait 5 minutes at least so the condenser for SRS system to goes out. (if you unplug the battery terminal you will have to reset many things)
3. Remove the steering wheel airbag and steering wheel until you find the split ring. Unplug the connector, under the dash and remove it from the steering column.

Problem might be related to the ambient temperature and/or humidity.

Good scanner software will indicate faults that are pending, that might cause trouble in the future or occasionally but not switch on the engine light and record a fault.

There is no substitute for careful and systematic manual checking in a back to basics fashion. It would have been helpful if you had described rough running more fully - was it hunting, surging, misfiring?
The first two can be associated with air/fuel mixture and the latter is often related to worn spark plugs, poor spark or perhaps even a failing cylinder head gasket.

Any number of thing's could be causing the problem , given the amount of electrical an electronic's on the vehicle ! Basic testing could uncover the problem . Voltage drop testing B+ power and ground circuits . Checking for DTC'S - diagnostic trouble codes in all the modules on the vehicle etc.... Do you know what a automotive wiring diagram is ? What a DVOM - digital volt ohm meter is an how to use it ? Learning how to test an not guess is how to find a fix . Anything you here on here would be a guess .

You have two on related problems , just a coincidence they stoped at the same time . The cable inside the cruise control module is probably broken , this cable is connected to the cable that opens the throttle . I'll post a video to show you what i'm talking about !
No Cruise Control Buick LeSabre You can buy this part for $10 to $20 buck ! Change it out in 10 min.
Now your other problem is the Blower motor isn't blowing air out of the vents ? The way you describe it working then on high only an now not at all this could be the motor . Unless the motor was bad enough to take out the blower motor resistor an the high speed relay as well.
Testing would need to be done to find the problem !

Check the idle air control as it is operating when you start the car and after the car warms up it is out of the system.

There is no expansion valve. There is an orifice tube in the high side hose where it connects to the evaporator inlet fitting. You'll have to let the freon out first to open this connection. Use needle nose pliers to grab the orifice tube. If the screen is plugged with aluminum mud, there are more serious problems with the system that will have to be addressed. Of you don't have the tools , a vacuum pump and a gauge set, I'd let a A/C shop do the job.
