What's up everybody?
I have a 2003 Chevy Suburban Z71 1500 5.3L
I just finished installing a Black Bear E-fan harness and a custom tune to turn pcm on for fan pin 42.
The problem I am having is, that as soon as the battery is hooked up, the fan on the passengers side starts running on high.
This is without the key being on or the engine running.
I pulled the relay to keep from killing the battery.
The good thing is, when truck reaches operating temperature, the left fan does come on normally.
Can someone tell me what is wrong and why does the other fan run wild??
Thank you,
