Hello I'm Paul and I will help you with an Answer to your Question

 

there needs to be a ground to Cooling fan 2

 

if you have no black ground you can run one from g102 to Cooling fan 2

 

cooling fan 2 should have a Green with Orange Stripe and a Good Ground from g102 (ground) click here for location of g102

 

cooling fan 1 has two green with yellow stripe wires

 

the resistor has Green with white and Green with blue...

The Green with red is only seen at the relays not at the fans.

Run a good ground wire from g102 to Cooling Fan 2 (both fans get ground through this wire and won't run without a good ground here)

 

if you can't find the black wire going to g102 you can just run a new one from g102 to Cooling Fan 2 (Black Wire in Diagram)

click here for location of Ground G102

 

let me know how you make out

I did exactly what you told me to do, i've connect the second fan wire with g102 and fans still not working; i did warm up my car for a while and the fan did not cut on; i've testes the fan resistor with a multimeter and it shows reading of (5 ohms)...fan still not working at any engine temperature,,,

Expert:  Paul M ASE Master replied 11 months ago.

without knowing what was done with the vehicle and why the fans are not factory I would not be able to help much further as to why they are not running

 

all I can help with is the way the factory has them hooked up

 

I will opt out to see if any other experts can help with this
