I have a 2003 Jeep Liberty. The radiator cooling fan stopped working and the car almost overheated. I replaced the relay with the new style with the cooling pins and the fan now comes on, though intermittently. When I drive it with the A/C on, it works initially. If I stop somewhere and get back in the car, the A/C will only blow hot, and the temp gauge will go up if I stop in traffic. I can hear the A/C clutch kicking on and off continuously at this point. Sometimes it works, sometimes it doesn

I have a 1987 Toyota AE82 4AGE Twincam 16. The cooling fan on the radiator keeps running. I changed the temp sensor on the thermostat housing but it still runs continuously. When I pull out the plug from that temp senor, the fan stops. Seems to be working the wrong way. There are no other problems with the cooling system as it works fine, but the fan is killing my battery.
Did you try replacing the sensor again? you could have got a bad one? ... 1988 Toyota Corolla 4 Door
I have a 1998 Mitsubishi Galant. I have a problem with the cooling system and air conditioner. I removed the thermostat and flushed the radiator already but the car still starts to overheat whenever I come to a stop and cool down as I drive down the road, the air conditioner also quits working at an idle. It has an electric [dual] fan system that is not belt drive and the air conditioner works while going down the road. The fan was also working when I let it idle and watched it with the hood up.

Toyota Ipsum/Picnic, 1997, 2L, 3S-FE. Radiator cooling fan stays on all the time. 2nd cooling fan for air con. also was staying on, but has since stopped working. Problem is probably there since I bought the car but not noticed 'cause I thought the a.c. compressor sound was the fan coming on. Kieran.
