Hello all, I had a guy helping me with fixing my car up when needed and he hooked up the bosch scanner and let the car run while checking the temp the fans kick on and cycle but when temp reaches 200 to 260 they never kick on again im going to try and tackle this myself so i was hoping someone on here might have any ideas... thanks!!

the fan module (located in the driver side fan) is probably flaking on you when the engine bay temps rise.

it is built into the fan so you'll have to replace the fan.

from what it sounds like, the coolant temperature switch is giving proper readings to the ecm.

do they both come on when the engine is cool and the AC is on?

Thanks for your info! Yes when the engine is cool and AC is on they kick on, but he turned on the AC while engine was hot, and he said they should def. Come on with the AC on and they did not.
