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,

That looks pretty close.
My issue with it is expecting others to do the work to read something so one can be lazy when it comes to writing it.
If YOU need help, YOU should be the one doing to work to get the question across.

My guess is this guy will never come back anyway, since we see a lot of these one-and-done style things, but still... :lol:

I hate reading a post like that also... :fume: :gunguy:
I just did it because I was bored and didn't have anything else to do... :lol: :lol:
