AC condensor fan will not turn on
 
Compressor is cycling, coolant is full, fuse is good, relay is good, fan motor is good ( tested with a jumper form the battery ). Is there a sensor switch that controls the condenser fan that may be bad or am I looking at some high dollar computer control? :4-dontknow:

Thanks all

Have you verified the power and grounds in the IPM? This diagram should help you with that.

Thanks RamTech,
How do I verify power and ground IPM ? If the IPM is good I'm guessing the next to check is the condenser fan relay control. If so, where is it located?

The relay is ground controlled at terminal 86 which comes from the PCM. You should have power at terminals 30 and 85, at all times. 87 feeds power to the fan so it will only be hot with the relay closed.
