QuestionQUESTION: A new radiator and air condition compressor were installed in my 1988 Eldorado and shortly thereafter the cooling fan fault and B441 history code appeared. I followed your procedure to clear the codes that you previously sent to me via email and the cooling fan fault message comes on again. It only happens when the air condition is running. This appears to be an ongoing code problem......Can you help me.....??

QUESTION: Yes, in fact, I cleared the computer twice as you recommended. When I started the car, during idle, the cooling fan fault msg came on. I checked and the B441 History code appeared. Do you think that my cooling fan has a problem..?? I cleaned the relays and replaced the cooling fan relay and cleaned the elec plug under the elec fan and replaced the radiator cap.....
AnswerThe fault is most likely the cooling fan control module.
