I am wondering if my issue is in the tune. I have wired my dual fans up like the photo attached. When I start the Fan1 it works perfectly. When I start fan#2 the relay just clicks. Checked all my wiring and it is correct (best I can tell at least ) so I wanted to see if I messed something up in the tune.
Thanks for the help

Fan 1 is set to come on at 200 and off at 234,surprised it works. System/ A/C tab, set re circulation fitted to fan #2 it will stop the relay from clicking and it will work normal
I was messing with the values trying to get it to come on early when I was running the truck. I need to reset those temps to stock f-body. I will try the recirc. Luckily I found in the very scanner where you manually turn on the fans. That made troubleshooting a lot easier. What do you recommend for the high and low temps for fan#1?Originally Posted by 89 Caprice 6.0L
My fans are set at-Fan 1 on at 195 off at 190 Fan 2 on at 198 off at 191,give you something to start at.
That sounds like more what I would expect. The 01 fbody tune I pulled off the repository is set at 226 on and 219 off which I thought was awful high, fan 2 was 234 and 227.
I have a 2006 Silverado 5.3 and the fans are set at those temps stock.My car is a 1989 Caprice with a 6.0 and 4L80e trans and with a 4 core aluminum Summit radiator and shroud kit with 2 fans.The temps I posted is what I have my car set to.On the right side of the Fans tab is a setting to run fan 1 when the key is turned off,I have mine set at 195 for 60sec.
Factory thermostats are usually 195 or 198, that is why the fans are set so high.I have a 180 in the car. It depends on which thermostat you have as to how you set the fans to run.
