from what i am told the fan relay is some where on the intake manifold most likely on the driver side
There is an ac relay on the grand caravan. It is mounted on the inside of the driver side fender.
drivers side firewall or behind battery
First, there is a fan relay mounted under a black plastic cover on the drivers side inner fender. There is also a "coolant temp sensor" which tells the computer to turn on the fan. This is mounted on top of the engine, next to the thermostat housing. It simply unscrews to replace it. Before changing it tho' check that the fan is working. With the engine running, pull the connector off the coolant temp sensor, the fan should start working. If not then the fan motor or the fan relay are faulty.
i'm having the same problem, the relay is under the hood, drivers side in fuse box.
I could be completely wrong, but I think they share the same sensor. If there's two sensors for the coolant, one usually goes to a gauge and the other is used by the computer, which in turn controls the fan activation and speed.
I had a 1994 Grand Am SE and it had the same problem. The fan is probaly not working. When you are going down the road, air enters the front of the car and helps cool the radiator and engine down. When it is sitting the fan should come on. It could be a relay, but it probaly the fan. We had the fan replaced and that fixed it. i had that problem too. if you have the know how you can hook up your existing fan straight to the battery to see if it is indeed a relay or the actuall fan. if your fan still works then try the relay. you can also hook up your fan to a toggle switch inside the vehicle, or run it to a switched hot terminal in your fusebox and it will run as long as the car is on. I also had the same problem I just took the fan out cleaned it and oil and greesed up the motor and insie and now it works fine. I had that problem too, I changed the engine coolant, and somehow that fixed the problem.
someone obviously did your head gasket wrong. if it's a 3.1, did they bleed air from system using the valve on coolant rail. this can cause air trapped in the system to boil the coolant.
Fuse or relay, or the fan motor may be out
do you have to remove fuel tank to replace fuel pump
Zerex antifreeze coolant
check see if its gitting power if it is then the motor is bad if no power check relay
