Question about 1992 Saturn SL
What is a code 26 it says quad driver module. What do we do to fix the problem?
That code is your egr valve or your egr solenoid.sometimes you can remove valve and clean thoroughly with brake cleaner for a cherap alternative.

I had this [problem. Tried the changing the EGR, the selenoid, after hours of looking it was a bad coolant fan motor pulling too many ohms and eventually blew the 30 amp maxifuse.

Code 26 is a soft fault code. You need to replace the egr solinoid and the ccp solinoid. The egr is on the valve cover, the ccp is on the back side of the block, under #3 intake runner.

Valve slash and clearance adjustments should only be performed by certified mechanics and is not a job for the garage or novice hands on type.
If you still decide to proceed, I suggest you get your hands on a maintenance manual which will list the procedure step by step, including proper torque values.

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

Testimonial: "Thanks I'll check those circuits,but could not find a test for the egr module,but did find for linear egr valve."
Tips for a great answer:
MIL (SERVICE ENGINE SOON) telltale circuit
Upshift lamp circuit
Cooling fan relay circuit
A/C relay circuit
Fault detected for 5 seconds for DTC P1651. Fault detected for 20 seconds for DTC P1650.
Important: The QDM circuit is continuously checked when the engine is running.
