Hey guys, I had my jb4 installed today and i noticed when i drive i hear a loud noise. I opened my hood and it was my fan. It doesnt stop till i turn off the car. I turned it off from my steering wheel but still doesnt do anything. Anyone experience this problem? Thanks in advance!

Sounds like Maxcool or 2ee3 error...is this a new JB4 or did you buy it used?

if its code 2ee3, check pins 4 and 17 they were switched on the jb4 that you sold me i had the fan blowing like crazy also but i did alittle diagnosing and found that this was my problem, maybe its the same problem on your set up, mine runs great now
