Have Ford Questions? Ask a Mechanic for Answers ASAP
Hi, I’m Ron and I can help you.I have been in the auto repair business with my own shops since 1975 and also teach automotive repair. I am confident we can resolve your problem together. Please understand that I don't know your skill level. In most cases when you have a problem with the way the vehicle performs, specialized tooling is required to acquire computer data/information or engine testing results. We didn’t build these complicated vehicles; we just diagnose and fix them. Also understand that I can't see, smell, hear, or touch the vehicle either, so it may take a few replies to get to satisfactory results. I am also going to direct you with the fastest, easiest and most common things to check first. Please be patient and permit me to do what I do best.I also try to give all of the information you may need, expecting a “positive rating” in return. I will also continue assisting you after you have rated me, if necessary. If there is any reason I cannot get a positive rating, please let me know why “in advance”, so I can go another direction for you. I am sorry you’re having this problem; I’ll help you through it.
This is all controlled by one of your modules and the only real way to test it is with a scan tool set in bidirectional mode where you can operate the fans from the scan tool. There can also be a programming issue that can also fix the problem, we'll know more later after the scan has been done.
Okay, a scan tool costs over 6K dollars. The dealer should have retested their TSB to be sure it went in right. The module itself may be defective then.
Thanks again, and please don't forget to rate me and keep this link in case you need me again later on.
