Question about 1993 Saturn SL1
The definition of the code requires that we have the code first. The code can be extracted with a scan toolplugged into your on board Diagnostic system on your vehicle. Code in hand, we can proceed. Most auto parts stores will use a scantool to get this informationfor you at no cost. Good Luck and thank you for using Fix-ya . -Ned-

A quad driver is a electronic component in the computer that controls one or more circuits on the car.you can find repair companies that specialize in computer repairs to fix you computer and they can also check the rest of it as well.you will have to find what circuits this driver controls and have it checked out from the computer out to the controlled components,as the circuit could have caused the quad driver to fail.

well the quad driver may not be at fualt and most likely is not.
there is a fualt line that the computer uses to monitor for fualts but the thing is one line monitors four different things and the code is to get you in the general area but not to the exact fualt. so from here you need to test for failed components. that code and the quad driver monitors the a/c , evap solniod , egr solenoid and coolant fan relay. the fan relay and egr are the most common i see all the time. and with you having an isssue with that coolant light i want to say check the fan circuit.
let me know if you have more question thank you and good luck
