Thanks for choosing Just Answer . I'm Wolfgang here to help!!

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.
Below is my first answer or request for more information. If you do not understand it, or you need more information from me, or need me to go in more detail.

Expert:  Wolfgang replied 5 months ago.

I NEED YOU TO CHECK FUSE F24 MAKE SURE IT IS GOOD AND MEASURE VOLTAGE ON THAT FUSE TO MAKE SURE YOU HAVE 12 VOLTS. AND HAVE 12 VOLTS AND AT PIN 2 AT THE 4 PIN CONNECTOR OF THE FAN.

THEN CHECK THE RESISTANCE OF THE FAN CONNECTOR PIN 3 TO ECU PINS 50 AND 90 OF THE T94 PIN CONNECTOR. MUST BE LESS THAN 1 OHM OF RESISTANCE
