Hi, just want to see if this is normal. Every time I step on the gas the fans do not blow any air at all, as soon as I step off everything works O.K.
2000 Ford Ranger XLT V6 2WD
I love this truck but it has so many of these little problems...I had heater issues before which seemed to be a common problem with Rangers

 

Should do that (cut out the A/C compressor clutch) when it's floored or when engine's heavily loaded, but generally not at part throttle/ General idea is to give more power to the wheels when you want it most.

 

fan as in blower motor?, if the air blows out of the defroster vents, you have a vacuum leak or a bad check valve.

 

Vacuum leak on the front right side right behind the intake, but lower about where you cant see it most likely. Did you do any work on the truck lately?
