my car is a corolla 93 GLi. I noticed my temp gauge seems to go up than normal. I noticed that the only fan moving was the smaller fan (A/C fan). I decided to replace the motor of the bigger engine fan. however, now i noted that when the aircon is turned on, both fans work which is i guess normal. BUT, when you turn off the A/C the bigger engine fan doesn't automatically turn on when the engine reaches a certain temp. hence, my car overheats when the A/C is turned off.
???
What's the problem?
How to fix it? thanks
