Question about 1999 Ford Windstar
If the air conditioning is turned on the AC fan is not turned on until the the high pressure of AC rich 350psi.The when the AC pressure low to 200 all fans truned off.
does your car's engine is straight to the radiator?. meaning does it has its mechanical fan attached to the water pump of the engine?
if that is the case, then the ac fan that you are reffering to is the auxilliary fan where in it is triggered by the high pressure switch.
that is just normal for that fan to run at 350 psi then turns off at below 200.
that only means that you are low on gas because the normal pressure of the condenser is 250 psi.
if you are under charged, the pressure drops below 200 and cuts the fan, as the fan stops, pressure again shoots to 350 and triggers the fan back on, and so on..
but if the charge is correct, as you turn it on the first time, the pressure shhots to 350, cuts the fan on, pressure drops to 250 at full charge then the fan would no longer stop.
i hope i was able to solve your problem...
pls rate me
