SOURCE: A/C fan and radiator fan aren't working

There should be a relay controlling them, check the relay comm for power.. You can connect the radiator fan driectly to the battery to prevent over heating. It has two wires, splice them and connect them to the battery via 2 other pieces of wire. In my opinion its very difficult to actually help with this one remotely since we would need to be on spot to test the circuit. I strongly suggest haveing an autoelectrican check this for you. YOu can connect the radiator fan directly to the battery to help you get there..

BTW the radiator contains a thermostat. this turns the fan on and off, of this is faulty you will have the problem you described. check the thermostat in the radiator.

SOURCE: The fan on my 2004 SAAB 93 convertible will not shut off.

I would suspect that the cooling fan relay ( in a relay / fuse box under the hood) is stuck. There are 2, a high and low speed relay. Pull one and see if the fan goes off. Once you have identified the culprit, see if there is an identical relay in another location that you can swap into place to verify the problem is fixed.

Jump a wire from the battery to the hot lead on the fan -- see if it turns -- if it turns, check the fan relay.

Take it to a SAAB dealer for an estimate to re charge or estimate for repair. May even be the belt has come off if it is driven by the fan belt.

Heat temp gauge on motor if faulty can it effect the cooling temp of the air conditioning on a saab 93 convertible 2002 model


No. The engine temp sensor affects engine idle speed, and timing. There is an in car temp sensor that controls the position of the blend door and the fan speed if the system has automatic temperature control.It also cycles the AC compressor clutch and the radiator cooling fans.

I have a 1996 saab thats keeps over heating everytome i add coolant & water to it it never stay n it runs out to da ground when i drive it i hear a funny clicking noise n da engine steam comes through...


Physically look in the radiator under the cap when cool, for coolant level, and check the valve in the cap for sticking. If air is present in the radiator it can't get out, and more coolant can't get in,(from the overflow). Either clean the cap or replace it and check that it is the CORRECT cap.
Radiator fins dirty, clean with a strong stream of water, not high pressure water.
Radiator clogged, try backflushing it, or replace.
Thermostat stuck open or shut, replace it.
Water pump worn out, can no longer move enough coolant, replace it.
Fan shroud broken or missing....
Electric Fan(s) not working, Check the fan, relay, fuse and engine temperature sensor's.
Belt driven fan, belt slipping, fan clutch is bad, fan blades have flattened out.

Air dam under front bumper is gone, loose, or broken. It actually has a purpose other than scraping on the driveway or curbs. It forces air up into and thru the condenser and radiator. If it's loose, airflow can actually push it out of place making it useless or blocking the airflow. Along with that, there may also be a plastic piece attached to the bottom of, and wraps up behind the bumper. If it's loose, airflow can actually push it out of place blocking the airflow. Simply reattach it with 4 or 5 screws.

Also, if the vehicle has A/C and electric fans, one fan is dedicated to the A/C and should come on almost the instant the A/C is turned on. The engine fan will run even with the key off, that is normal. The system is trying to cool itself. Hope this helps.

You can simply replace or unplug the sensor. Unplugging it should turn off the warning light and won

Driving in very hot weather, stopped at light,


you may have blown the head gasket.
or
check the coolant level,is it low?
if it is ok,check the fan switch on the radiator,change the thermostat,and check that the fan is working.
the fan has to work,saab engines run very hot.
there is a after run fan switch as well that measures engine compartment temperature,and can start the fan even with the car off,so be careful.

1994 Saab 900 S convertible running hot


You don't say whether your electric fans both work...

First, check fuses #25 and #6 (both 30 amp)

There is a fan thermoswitch is on the left side of the rad. Turn the ignition on, and after pulling back the boot, short across the two terminals with a screwdriver.

If the fan runs, fan and wiring are both good, but thermoswitch might be faulty.

If fan only runs when thermoswitch is shorted like this, switch needs to be replaced (I strongly recommend that you get the low temp switch to prevent overheating - your temp gauge will not go over the middle position even on the hottest days; also get a low temp thermostat,and ALWAYS get a Saab stat, not an after market one! The SAAB stats are three position, and most after market ones aren't)

if the fan doesn't run when switch is shorted, check for voltage between green wire and ground at the switch.

Voltage indicates faulty fan, if no voltage then check the fan relay J in the main fuse box for the A/C rad fan, and also check relay G - it's for the rad fan.

Hope this helps!

Radiator fan won't kick in


On my slightly older Saab the radiator fan is electric and only is engaged when the temperature meter reaches 3/4 to the top.

When the car is in motion it will not spin since the air flowing through the radiator from the speed is sufficient to maintain normal engine temp. Only when the car is still it for a few minutes it may start to spin especially during summer, it will sometimes continue to spin even after the engine is turned off. This is normal behavior for this car.

To conclude, if your engine temp only goes up to half the gauge there would be no need for the fan to start spinning. If it doesn't engage during the conditions I described above there would be a problem that needs to be fixed.
