indicates a blocked radiator cores
not using a thermostat can cause overheating as it allows the movement of coolant to be to fast to allow the transfer of heat from the coolant to the air

Remove the seat belt mounting bolts at the bottom. Then there are 4 retaining clips on the top that get released by using a flat bladed screwdriver between the seatback and the upper shelf. Push down to release them.

Ck the power at the solenoid. You should have 12v off the battery going in... a equal sized ground wire on the other side & a signal wire/key power to trigger the stater to turn it over.

Your car should have a dip stick that tells you where the oil level is. Use that to determine how much oil you need to add. Add 1 qt at a time until the oil appears on the dip stick, then add the oil slowly, checking the level until it is in the hash marks on the dip stick. If there is no dipstick, drain the oil and measure the oil using a gallon or quart containers and add the recommended amount. Remember there is already about 1 qt of oil in the filter.

I don't have a diagram, but your problem is the oil cooler underneath the intake on top of the engine. Remove the intake, and the cooler is right there in between the heads. Easy to change once you get the intake off. This is a VERY common problem on Cateras, and the symptom of it is oil in your coolant. I have a 1998 Catera and had the same issue.

Check a wiring diagram an check power an ground for those systems . Also read factory service information on how they work . Electronic modules involved . DDM - driver door module . If this vehicle came to my shop , first thing I do , hook up factory scan tool an check input data from the door switch to the DDM . Check DTC'S - diagnostic trouble codes .
The power windows system consists of the following components:
• Driver door module (DDM) -- GMLAN device that receives and transmits messages and signals for window functionality
• Passenger front door module (PDM) -- GMLAN device that receives and transmits messages and signals for window functionality
• Left rear door module (LRDM) -- GMLAN device that receives and transmits messages and signals for window functionality
• Right rear door module (RRDM) -- GMLAN device that receives and transmits messages and signals for window functionality
• Driver door switch assembly (DDSA) -- GMLAN device that contains the driver, front passenger, RR and LR window and window lockout switches
• Right front power window switch -- provides switched ground window switch signals to the PDM for the front passenger window
• Left rear power window switch -- provides switched ground window switch signals to the LRDM for the left rear passenger window
• Right rear power window switch -- provides switched ground window switch signals to the RRDM for the right rear passenger window
• Left front power window motor -- contains position sensors and a module that receives signals from the DDM and provides a status signal to the DDM
• Right front power window motor -- contains position sensors and a module that receives signals from the PDM and provides a status signal to the PDM
• Left rear power window motor -- contains position sensors and a module that receives signals from the LRDM and provides a status signal to the LRDM
• Right rear power window motor -- contains position sensors and a module that receives signals from the RRDM and provides a status signal to the RRDM
• DRIVER DR MOD fuse (10-amp)
• FRT PASS DR MOD fuse (15-amp)
• REAR DR MOD fuse (10 amp)
• Power Window Motors Circuit Breaker (30-amp)

Your best bet , take it to a qualified repair shop.

It could be the electrical portion of the ignition switch. If the computer is not energized it will not display the check light. The switch has multiple power feeds and it may be at fault.
