Hello all,
I am new to this forum.

My condenser cooling fan does not seem to work correctly.
I have checked all fuses and relays and jumped the fan
to the battery - and they are all fine.
Also the compressor is working and the system is cooling.

The problem is the condenser fan will not come on when I
turn on the A/C. I have to rev up the engine rpm's to about 2000rpm before the condenser fan will turn on.
The radiator fan is working.
So the condenser fan works, but not until I rev up the rpm's.

So could this be an electrical issue with pressure switches
or the diode between the a/c clutch relay and the condensor relay. Or is the system so sensitive to freon
levels that it could be slightly low on freon ?
I live in Texas, we have had many days of above 100'
temps. and I really don't think the freon is low as the
system is cooling. In the heat of the day when the car
is at idle, occasionally I can here the a/c clutch or switches
clicking/clunking off and on and this will also pull some
extra power from the engine - lowering the idle below 500 rpm. And when I pop the hood, the condenser fan is usually not running - but the system is still cooling just
not as well as when I am driving.

Thanks for your help !

check your resistor module, it might be bad...

dont really know how to check if its good or bad, but...
thats the one that makes the fan turn on, i had to buy a new
one, but come to find out ...my fan was bad...
check my thread...

its located inside the ac unit/fan housing...

Thanks for the reply !

Well, I had my mechanic diagnose the problem and if
I were not there armed with diagrams and test procedures he probably would have done the most
simple test first. Tap the fan motor with a hammer !!!

Duh.....it never crossed my mind to do that.

I had removed the fan to jump it with a 12v charger
and it worked every time.
The fan motor has some sort of short, and since I had
removed it to test, it was being bumped around just
enough to make it work when tested.

That's why the fan would not work at idle, but when I
kicked up the rpm's a little the engine vibration
would shake the fan just enough to close the short
in the motor.

Bottom line......before you remove any connections, fuses
relays etc.. just bang it with a hammer and see what
happens.

and thats what happened to me...
did everything plus the thermostat and come to find out it was the fan...
