Coolant fans

Hi my name is Holden and I’m currently
having trouble because my coolant fans wont
kick on for my 3100. As far as things I’ve
done I’ve, replaced head gaskets, cleaned
out coolant ports, replaced upper and lower
intake manifold gaskets, I’ve replaced the
temp sensor. Checked all fuses. I tested the
thermo in boiling water and drilled a 3/32
hole for north installation. Things to note is
the hoses are shit but I don’t think it would
stop fans from engaging. When I unplug the
temp sensor fans engaged.( but it is a new
sensor) interior fans do not work but worked
when I bought the car. I think blower motor is
bad. When flipping on ac there is not affect
on the fans kicking on. Please ask as many
questions as you want I just don’t understand
why the fans do not kick on. Car is 200 k and
I did put 50/50 green coolant in the vehicle
even though it calls for dex. I still flushed out
the entire coolant system
