Question about 2002 Dodge Grand Caravan
Seems like my radiator fan dont start...maybe a relay problem maybe a fan problem. How can i determine wich piece is not working properly?
To check the fan motor you would use a jumper wire to bypass the relay. You can also swap the relay with another one that has the same configuration.
You may need a wiring diagram to trace the wires.

SOURCE: 2002 caravan, heater problems
That was a common complaint a few years back, due to the fact that the heater core is a little too much higher than the engine, which requires that extra push it gets when engine RPM's increase. One thing I did do on my Caravan was remove my hoses to the heater core, and use a small external pump with hoses to circulate C.L.R. through my core for a while, then let it sit with CLR in the core overnight.Next day I circulated it through again, both ways by reversing hoses, and then re-attached hoses, bled air out of system, and notice quite an improvement in heat at idle. Once cleaned out, the heater core allowed coolant flow through it better at idle. If your stumped by explanation, take it to an automotive shop, or a Rad shop, and get a quote on flushing that core out for you. I recommend the CLR, but it might be too time consuming for you , but a flush will probably show some noticeable improvement.

First thing I would check is the fuse or the fan relay, located in the power distribution box under the hood. If that's not the problem, then I would find the coolant temperature sensor, unplug it with the key on and the fans should run.
