I had a similar probem with a Saturn. On hot days it would heat up at idle
unless the AC was turned on (which activated the electric fan). The cause
was a faulty coolant temperature sensor, which, once I found it, was as
simple to fix as screwing out the old one and screwing in the new one. If
the relay were bad, the fan wouldn't come on with the AC.
