If you do a lot of stop and go driving, you to have a fan that works. I haven't looked at your wiring yet, but, if voltage and ground to the fan are good and no fan operation, suspect a faulty fan.
Do you have a radiator cap, if you remove it, can you see the coolant? If so, with the thermostat removed and everything hooked up. Drain some of the coolant down just till you can see coolant passages. Start the vehicle, flow should be instant. You should be able to see coolant movement.
Here is the fan wiring diagram, top wire is voltage, black wire is ground. Check both.
