Default Code 26 Quad driver module????? I need help!!

Hello again everyone,
I recently had my car at the shop for a pivot switch in the steering wheel. They replaced the switch and now while driving it home i noticed the cruise doesn't work and my check engine ligh came on, so i checked the codes and came up with code 26. My alldata tells me it'* a quad driver module. Anyone have any ideas what they may have not hooked up or forgot to plug in? I'm going to take it back to the shop, but i would like to know for future reference.

Thanks,
Sellncars

The PCM actually watches the low speed fan relay for the proper voltage. I'm forcing it on when the PCM doesn't want it on. The other items the Quad Driver A module monitors are the Evap canister purge solonoid, the HIGH TEMP light, and TCC apply. Note that it does NOT monitor the high speed fan relay. Only the low speed is considered critical?

Quad B covers the shift solonoids and EGR valve.

Hi guys,
Ok, It looks like I'm going to need a computer, not a problem. This code 26 comes up and i still dont understand why. Everything works, the car runs great, except for the cruise, Courtesy light doesnt work now when i go to open the door, or when i lock the car anymore. I think they forgot to plug the cruise up when they had the steering column apart or maybe a blown fuse? I've had computers go before and they cause mostly a no start condition or a poor running car. This problem really stumps me. The car runs fantastic!!

What are the fuses for on the passenger side footwell? Does anyone have a diagram of what fuse goes to what? My chiltens book and alldata dont show it. Does anyone have a picture of this fuse box?


Thanks,
Sellncars

Not the fuses in the passenger footwell. They're not shown in the owner'* manual. Only those under the column are.
