2007 Jeep Compass 2.4 The Cooling Fans wont come on

Hi

I have a problem with the cooling fans on my 2007 Jeep Compass. The fans themselves work just fine wired Directly to the battery to keep them running. This is what I have manage to find out on my own. Anyone have any ideal where the Fan Relays are?

RADIATOR FAN WILL NOT OPERATE, GAUGE READING HIGH OR HOT (POSSIBLE CAUSE)
1. Fan motor defective - Refer to appropriate Powertrain Diagnostic Procedures manual for operation of the scan tool. Repair as necessary.

2. Fan relay, powertrain control module (PCM) or engine coolant temperature sensor defective - Refer to appropriate Powertrain Diagnostic Procedures manual for operation of the scan tool. Repair as necessary.

3. Blown fuse in power distribution center (PDC) - Determine cause for blown fuse and repair as necessary.

GAS ENGINE
Radiator fan operation is controlled by the Totally Integrated Power Module (TIPM), with inputs from the engine coolant temperature sensor, continuously variable transmission (CVT) oil temperature, and A/C head pressure. The (TIPM) turns on the fan through either the high or low speed fan relay. The PCM provides a ground to the relay's control circuit. The fan relays are located in the (TIPM) . Refer to the label beneath the (TIPM) cover for location of fan relays.

Hope this helps.
