The Quad drivers are located inside the car's ECU/PCM also know as the "Computer" or "Brain". The only way to replace them is to replace the ECU/PCM. The ECU/PCM is located: FRONT SEATING AREA, PASSENGER SIDE, UNDER DASH, MOUNTED BEHIND GLOVE COMPARTMENT CAVITY. The ECU/PCM should be easy to obtained from any of your local autoparts stores. Be aware that most cars in junkyards are there for a reason, they don't run, and I would not suggest replacing the ECU/PCM with one from a junkyard. If you do not correct the reason the quad drivers failed in the first place you may damage your new ECU/PCM. Typically an electrical short in the wiring associated with the quad drivers is At Fault. Check a shop manual to determine how to check the wiring associated with the quad drivers. If the Quad driver module sets a code, this usually means there is a fault in whatever is being controlled, not the quad driver itself. For example, some Saturns would set a Quad driver fault when the EGR valve stuck open. Replacing the Quad driver would not solve this in any way. If you are not completely sure what set the code, take your vehicle to a professional (or waste a lot of money replacing good parts). == == I got a code 26 on my 1992 Buick Century, one of four codes designated Quad Driver Module. I was unable to find anything saying which components that code is associated with, but I read they are each associated with as many as four (hence "quad" electronic components, generally solenoids such as the one metering the aforementioned EGR, plus the TCC (torque converter clutch--which is also tied in somehow with the brake light switch), EEC (evaporative emissions control purge solenoid, and maybe the radiator fan relay and I suppose by association the temperature sensor. Anyway, I just checked all of those things that I had (no EGR on this car) or could locate for anything obviously wrong, and found it: The two wires to the EEC purge solenoid were cut! Looked like someone had intentionally snipped them off with a pair of wire cutters. It's still a mystery to me how they got that way, but I reconnected them and -- no check engine light.

Where is the quad driver module on 1995 Saturn SW2 reverse lights and windows will not work?
The quad driver module on a 1995 Saturn SW2 is found in the car's ECU/PCM, which is the cars computer. If there is something wrong with the computer then the reverse lights and windows will not work.

How can i fix the quad driver module on a buick park avenue 1993?
the quad driver module is a component of the ECM. you must replace ECM.
Can you change the Quad driver module on a 95 Saturn SL2?
The quad module is in the computer.....Most likely the problem is one of the sensors it controls....Most common is cooling fan relay or motor OR EGR solenoid, or Evap purge solenooid
You are getting a quad input error on a 1994 Saturn coupe how do you correct this?
the quad driver is a individual circuit within the PCM. you will need to replace the engine computer (PCM) in order to correct this issue.
Where is the Quad Driver Module on a 1993 buick lesabre?
the quad driver module is part of your computer, it controls certain parts like your emission system and fuel system that sort of stuff.
1994 Pontiac transport has a quad driver module failure how can this be corrected?
Look at your error codes again. It should read something like "quad driver module FAULT" not failure. It is VERY unlikely that your quad driver actually died. It is the high power control system that is in your computer. So replacing it, means replace the computer. To prevent this the Quad Driver has all sorts of internal protection hardware in its design. The likely thing that is wrong is something the Quad Driver is connected to. And that The quad driver isn't seeing every thing correctly so thus the Fault. It also can fault if there is a wiring problem from the device to the quad driver. There are Test for each component. You should to to find out which is the problem. Consult your Shop Manual.
Where is the quad driver module on a 1989 Buick 3800?
If a quad driver has gone bad it is necessary to replace the ECM. After replacing the ECM, drive the car on a bumpy road and note whether the check engine light comes on. If it does, fix the problem or you end up with a repeat QDM failure. == == == == There is no such thing as a quad driver module. There are quad DRIVERS in the ecm.
Where is the Qaud Driver module located on a 1991 Buick Century Custom?
Quad drivers are small chips that perform on off functions inside the Engine Control Module. If you have a code which states there is a Quad Drivers Error, you need to check the items that that particular Quad Driver is controlling. For example, the a/c compressor relay, or trans solenoids etc...
You got a code 26 Quad Driver Module do you change your whole computer what should you do I have a 1993 Ccamaro Z28?
I would take it to a repair shop and have them check it out. If indeed the quad driver is defective you will have to replace the computor.
Your 1992 Buick Century has a DTC 26 code how can you find out what this is?
A DTC #26 is a Quad Driver Module Malfunction.
