I havinh a problem with not getting low speed fan when temperature hits 215-217 and the high speed fan kicks on at 226-228 it is at the low speed. If I turn the AC on the fan runs but still dont get high speed at any time. I have changed the ECT sensor, radiator fan. Checked fan fuse in the tipm and the relay in the tipm. Trying to get any help with this issue as my temps get to 230 and it has a hard time cooling it down because of not getting right speeds.
