Possessed 95' Olds 98. Anyone perform exorcisms?
 

New to the forum. Having issues with my 95' Olds 98 supercharged Touring model.
1) Check engine and traction control lights come on randomly car. Together or separately. Will stay on for minutes, hours. Cold or hot running. Temp is normal. Runs, drives fine.
2) When car has been driven for awhile and then sits running, idling, the low coolant light comes on and the chimes ring. Coolant is full, Engine temp normal for hot idling. Start moving the car, driving and it goes off after a few minutes.
3) Both front seats the power recline does not work
4) RF, RR and LF power windows do not work. At master switch or individual door switches. Lights do not dim when switches activated. Installed all new switches...no change.
5) Rear reading lights in headliner do not work. New Bulbs.
6) Cruise does not work
7) Right side temp control in door doesn't change temp. Stays hot. RS of dash always blows hot air. AC doesn't get very cold but doesn't say low freon. Compressor kicks on and off.
8) Trunk pull down stopped working.

Was grandfathers car and has been a good car but recently all of this is changing little by little. Odd car with the options. Maybe grand dad is riding shotgun...

Any help, insight would be greatly appreciated.

Thank you,
Ray
