AFCO heat exchanger issue

[SS6310]

Hey guys, this has probably been discussed before but I need help. I have just finished installing my afco heat exchanger with dual fans on my 2015 ZL1 and first let me say the instructions are crap! Anyway, I got it all installed and cranked up my engine to check everything and the fans did not take long to turn on, engine was not even close to being warmed up, and then they were blowing out and not sucking air in. I could not call customer service as it is Sunday. Any help with this issue would be great.

Blowing out Vs sucking is the wires are inverse, switch positive and negative should fix that.

As to when they turn on.... I wired my fans on a switch, so I might not be familiar with how you wired them in, also mine is an SS with ZL1 setup and AFCO.

Hope I helped at least a little bit.

Good Luck.

Thanks for the help, I knew it was something in their wire harness just wasn't sure what.
