Overheat when A/C on

[JDMrida]

My car's temp raises really fast when I turn on the A/C and quickly drops when I turn it off... whats the problem? I replaced the mechanical fan and a/c fan with 2 slim fans that are turned on every time I start the car.

I can notice a change in water temp when I switch on the A/C, my Autometer gauge shows about a 15 degree increase in temps.

I think it's like that because the A/C's radiator is in front of the engine's radiator and warms the air that reaches the engine's radiator.

It gets really close to the Hot letter though.. so its too dangerous to drive.

Electric fan relay could be bad. Check to see if your efan turns on when you turn on the AC.
