    hi there , thanks for awesome thread ,

    i bought the same harness and installed every thing to my 2004 GMC safari , and now i have high speed and low speed for the coolant , but for the A/c fans run at low speed only , any idea why , on low speed after 2 min the comp stop and i think because the pressure is gone high and disconnect for safety

    i couldnt upload my file here
    but you can look at it on hptunners web site
