A/C blows cold and heater works fine. The condenser fan in the front is not turning on which causes the engine to get hot only when the A/C is on.

Hello,

9 time out of 10 it will be the motor or the relay. here is a guide to help check the relay. We should check the fuses as well. I have included the wiring diagrams for the air conditioner so you can see how the system works. Here are the fuse locations as well:

See if the motor is getting power by using a test light on the blue/black wire when the system is on. Check out the diagrams (below). Please let us know what you find. We are interested to see what it is.
