2002 jeep grand cherokee

My 98 Jeep Grand Cherokee had the same problem. Over heated when standing still. Took it to dealer and they could not find any problem with cooling fan. After doing my own investigation I found out that the electric cooling fan would begin to seize up after about 1hr. of operating. (gets hot)

The dealer would look at fan and see that it was running and think its ok. The problem is, it wasn't running fast enough.

I have a relay on the right side of front fender and jumped the fan to stay on with motor off. (must know what your doing). After about 1hr. fan started slowing way down. Returned it to dealer told them what the problem was. They were not smart enough to jump the relay so they put a couple hundred miles on it even though i told them it works OK when moving. Make sure you tell dealer to use the relay to jump.
Replace cooling fan motor. Works great
