If your vehicle is overheating due to a non-working cooling fan motor, this video will show the steps involved in diagnosing the problem. Cooling fan motor testing (low and high speeds), relays, harness connectors...it's all here.

Generally, the low speed fan kicks on when the A/C is turned on or when the coolant temperature hits around 200 degrees F. High speed kicks on around 220F.
