Hello I’m fairly new here I’m not sure if I’m posting in the right area so forgive me.
I have a 2016 Yukon XL 5.3 2wd it’s been having electrical issues in the past year the headlights would always pulsate almost like flashing your headlights bright to dim. Just the headlights. Well one day it just stopped few months back. Especially when the fan would kick in but anyway the AC fan won’t kick in when I turn the ac on its full of Freon and I can see the compressor kick in. I also checked the fuses all good. Both fans are working I just checked them there on low as the engine runs. There’s only 2 fans that I can see. Back in the winter I went through and cleaned all ground connections that I can find I gotta get this figured out it’s my wife’s daily. I haven’t ran any codes and no engine lights on. Has anyone ran into something like this?
