The cooling fan relay on the 2004 Chrysler Sebring is in the engine compartment fuse box. There are actually two cooling fan relays in this fuse box. One is a high speed radiator fan relay and the other is a low speed radiator fan relay.
On a 2010 Ford Mustang : In the Power Distribution Box ( which is " live " ) located in the front of the engine compartment , on the passenger side Relay # 50 , full ISO relay , cooling fan relay ( High ) Relay # 55 , full ISO relay , cooling fan relay ( Low )
check the coolant temp. sensor, this sends info to the computer to turn on the cooling fan. Check for other answers for the cooling fan, I posed a answer on how to replace the fan relay with out removing the front facia and bumper
the relay should be next to the fan on the radiator shroud The radiator cooling fan fuse is #1 on the fuse box. The 1988-1989 Cabriolets have a two-stage cooling fan relay, which is mounted to the left fender in front of the battery.
You may have to replace the cooling fan relay or the cooling fan itself, I had the same problem and I first replaced the relay and it helped but then the cooling fan went out and I repalced it and now everything is fine.
