I'm having the same issue on a 2007 ford edge. I've replaced the fan module and thermostat. The big fan wasn't coming on until I changed the module but even now both fans only come on for about 3-4 seconds at the same time every minute or two and car will start to overheat if stuck in traffic or a drive-thru for to long. The A/c starts blowing warm air when stopped as well.
