Where is the relay switch for the cooling fan on a 99 Jeep Grand Cherokee Laredo?

I believe the 99 Cherokee has an electronic relay that is located behind the right headlight below the battery. If this relay fails it may cause the fan to stay on or not work at all. Generally it means the fan is drawing a high load and may have to be replaced. I have gone through two fans and 3 relays without any dealer support as to why this is the case. I do know that if you can maintain a minimum speed you can still drive it as this is how i drove to the dealer. Airflow through the rad from moving negates the need for the fan temporarily. Make sure that when the new relay is installed you ensure it is mounted securely as this connection acts as a heat sink and an electrical ground. It is to my understanding that this solid state relay is rated for 40A and the fan motor runs around 20-30A. Hope this helps.
