electric fans wont turn on
I've been searching and can not get my fans to work. at all. 2004 tahoe ECM 5.3 engine without a/c
pins are seated well in the plug, I'm using 3 relays and have checked them manually and they work both low and high speed with ground being applied like ECM would do ( if I read how to do it right )
here's my current settings from previous try.
enabled analog cycling from not fitted
changed low speed to 195-188 from 203-198
high speed 203-193 from 210-199
I've tried aux fans and 2 fans, I've messed with delays which went from 0.0 to now first stage enable .3 disbale .2 min time 90.0 and second stage enable 45.0, disable .3 time 210.
I havent tried serial cycling yet, but at this point I'm trying anything, and maybe thats why these look f'd if they are really indeed f'd up.
Could someone please help me out here ? I'm a total noob with this, but I have got the truck to start with no DTC's and she runs great. even logs speed correctly with gears and tires :)
Thanks for any help. I truly appreciate it
