So far what I've read is that the fuse for the fan is on the fuse block that is not replaceable with replacing the whole fuse block (attached to B+). The fan control module is PWM and you can no longer hook the fan directly to 12V (at least not without pullout the fan out and taking it apart). The control module is built into the fan assembly and gets the pwm directly from the ecm that controls the command mode 1-5. 1 being the slowest. So really not easy to troubleshoot at all. I can't find the frequencies for the command modes to test the ECM terminal 3 (carries the pwm signal) so really I just need to hook my fan up to another car and see if it turns on. The only problem is that really doesnt tell me if the fan or the fan control died.


This really isn't something a shade tree mechanic can 100% troubleshoot easily that's for sure.
