I have a 2002 model santro. I am facing heating problems in it. A couple of days back I had a leakage on the radiator cap a mechanic on the way made the fan direct temporarily while I reached the shop to get a new radiator cap. I drove with a direct fan for about 5 mins after that I replaced the cap refilled the water and made the fan auto again, the next day I went and had the radiator serviced too.
Now I am facing this problem that when I drive with the AC on the temperature remains fine but when I drive with the AC off the temperature goes above half and car heats up.
Where can the problem be do I need to replace some sensor ?
