    Maybe the engine is not getting hot enough for the high speed fan to turn on. The high speed fan always come on when the A/C is turned on regardless of temperature.

    Ive had it running hot to much for the low speed to handle because my rpms from idle drops like its going to stall

    I thought only the low speed fan comes on when you turn the A/C on and once the temp is about 111deg the high speed comes on then switches off at 109deg. Without A/C on low fan should come on at 104deg then off at 99deg.
