When the key is turned on the blower fan does not ramp up just stays steady
I asked about the ENGINE FAN.
When you turn the key on, wait 30 seconds, does the engine fan ramp up to high speed?
It is hard to help someone from 1,000 miles away, not answering my questions makes it impossible.
I still don't know if the ECM is powering up because you did not tell me what the engine fan does.
I am using the engine fan as a diagnostic tool.
