on a 1999 jeep grand cherokee where is the coolant fan relay
The engine computer uses the signal from the coolant temperature sensor to decide when to activate the radiator fan relay.
change the coolant fan relay
The coolant fan relay on a 1988 Chevy Celebrity with 2.8L V6 is on the radiator support bracket behind the right hand headlights.
In my '96 beretta the cooling fan relay switch is located on the drivers side strut tower. That may not be the problem. If your fan still won't work after changing the relay switch try the coolant temperature switch/sensor.
In the vicinity of the passenger headlight.
Several things may be the cause ...... fan no longer works, cooling fan relay no longer works, coolant temp sensor is bad, or maybe even the cars ECU is'nt telling the fan to come on. Ron J.
By running a ground wire-(jumper) across the terminals on the fan motor relay. Find the terminals that connect to the relay's switch, and short them out like the relay would do. Doing this will burn the electric fan motor out very quickly. Your best bet is to replace the relay and possibly the coolant temperature sensor. The sensor is about $16 and the relay about $14 and the fan motor about $38-$50 at Autozone.
Most of the 90s GM cars have the fan relay mounted on the fender near the battery.
how do I find the left radiator fan relay for an 1992 acura legend
bad fan or bad fan relay
The fan relay will be located in the PDB box in the engine compartment. The relay is controlled by the coolant temp sensor and the computer. Hope this helps.
