Sound like fan relay .relay for cooling fan is on back fire wall next to the strut tower on the passenger side.
Here are the cooling system diagnostic
steps...First does the cooling fan kick on (with engine hot)? If not,
check the fuse, if good then check the thermoswitch in the
radiator (it's about an inch and a half in diameter located on the
lower part of the radiator with two wires ) by disconnecting the
wires and touching them together (again, with engine hot...at least
190 degrees) if the fan comes on, you have a bad switch. If not
connect a 10 gauge jumper wire from the battery to the fan itself
(there are three terminals,,, one high, one low and ground). With
power direct from the battery (and a ground wire, if necessary) fan
should run... if not replace the fan assembly... if it does run then
you have a bad cooling fan relay. It will be located above the fuses on the fuse block... Hope this helps...;-)
Could be the radiator fan switch in the radiator,,,if thats faulty when the water temp raises the switch wont send signal to fan to kick in,,,also check the fan is working by connecting it straight to the batt some way to make sure its worken,,,

thank you for the hints, problem was the relay. working fine now. If anyone wondering which one is it, on my car was the first relay (4 total (starting from passenger side), if different position than mine, the relay is the one with black/purple wire, same color as on the radiator fan motor. just follow the wire to the relay
