Could be the relay, or the ac system may be low on freon.
The computer grounds the relay when ac pressure reaches 200psi.

How would my car run without the radiator fan


bubbling at the RAD cap to the expansion tank is.:
1: overheating, and all cars overheat, parked, running and no fan.
2: blown head gasket. or far worse....
3: bad rad cap, the gasket is bad in side it.

the FSM covers the fan test, read that.
or login to alldata.com and read engine cooling. section.

I have a 2006 vw jetta 2.0t and the fans stay on even after the ignition is off and key is out, will run until the battery is dead. I have replaced the coolant sensor and the computer sensor on the...


The fans are run by rad temperature, not engine temp on a VW.Somewhere on the rad you should see a wire harness plugged into it.That is a thermo-switch which turns the fans on and off based on coolant temp in the rad. My car is a lot older than yours but this switch is virtually hidden on the bottom driver's side of the rad. It has 3 wires going into it.There could also be another sensor attached to the engine block or head to monitor engine compartment temps after engine shut off. This will turn the fans on or off as well based on air temp in the engine compartment.

The car over heats while idling then cools as you drive


its the radiator fan running? check the fuses.
if the radiator fan does not run when the car achieves certain temperature, then your temperature sensor maybe defective.
check if you have enough coolant.

2001 mitsubishi over heating i have replaced the radiator,thermostat and car still heats up unless i turn on the heater so the fans will run , should the fans be on at all times what else should i check.


Did you make sure to have heater (not defrost) running while you refilled cooling system after repairs ? If not, try refilling with cap off rad, and heater on, and allow coolant to get to operating temperature, where cooling fan at rad should come on. I usually allow fan to come on at least 2-3 times before I put rad cap back on, to insure all air is out of the system. If rad fan doesn't come on when it should, you may have found your problem. If still heats up after that, get back to us and we'll assist further on diagnosing problem. Let us/me know how you make out.

It runs hot


check electric fans and fan switch!!!! :)

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!

Engine runs very hot


check if the rad fan is running optimally. Also, check the interval wherein the rad fan turns on and off.. usually, rad fan should be on most of the time... if it constantly turns off.. your thermostat is probably busted

Heater problem


is your heater set on defrost this will cause your engine fan to run because it turns on the compressor for air conditioner this helps to extract moisture from your warm air defrost  and the fan in the engine compartment helps keep it the engine cool from the extra load on the engine this is normal
