The fan will not turn on. Took fan motor out and tested it and it works. What do I check next. I check the fuse, it seem fine. Thanks.

Check fuses under hood as well as the fuse box located inside the vehicle.
If nothing still, sounds like your motor is toast.

Both should be a fuse under the hood, or under the dash, if there is a fuse link, it will be along the hot side of the wiring on the fan leading into source of power.

If the A/C is on the same circuit as the coolant fans, then the A/C motor is going bad and drawing too much current. A local shop should be able to test the motor for a small fee, or, if you know how to use a multimeter, you can check the motor's resistance for shorts. You'll need to know the original motor specs before testing; the motor model #, maker, etc., should be somewhere online, or available from the maker.

Hi Marie.

Test if there is voltage to fan motor with engine hot (use a test light or a Voltmeter). If there is 12VDC to fan motor and motor does not turn, then the fan must be replaced. An alternative way to test the fan would be energizing the motor by connecting it to 12VDC. If fan does not run when motor is energized, then the fan is defective.

If fan does not get power fuse, fan relay, thermostat and wiring must be tested. If you have already replaced thermostat, test the rest.

Check the fan fuse first. Most VW use a 30 Amp fuse located in the fuse plate. Refer to the car owners manual for fuse location. Depending on the year of your Polo there is a Coolant Fan Control Relay on the main relay panel. If the relay is good it must power the fan when the engine is hot. Before going for the relay check that two of the relay's contacts are getting power. If there is no power to the relay and fuse is good it means that there is a wiring problem.

try disconnecting the cluster fuse and the radio fuse and see what happen if everything work...u might have an open circuit or a short on one of the electronic in your truck

No if it is stiff to turn,it is bad,replace it,and make sure there is not a blown fuse on top of the cooling fan being bad.

Hi

Thanks for using FixYa. The possible causes due to which the blower is not working normally are fuse, blower resistor or a bad blower motor. Test the voltage at the blower with a test light. Please check the motor relay switch fuse under the dashboard. Use a multi meter to measure ohms for continuity. If these are fine, bypass the blower motor relay switch to make sure blower motor is running fine. Motor relay switch is right next to radiator fan relay switch under the hood. Pull out the blower motor relay switch to see 4 female pin holes. Test the relay switch using a 12 volts power source and a multi meter to measure continuity. If fan works after jumping the pin holes, then blower motor is fine but relay switch may be faulty. You may also need to replace the blower motor resistor. If still the problem persists, then you need to replace the blower motor.

Please do rate the solution and revert for further assistance.


Thanks

Mine did the same thing and I found the connector on the blower wiring harness was all melted and chared from overheating. I took out the blower assembly, cleaned the connector terminals, cut off the melted wiring harness connector and crimped on new female connectors. Seems to work ok now, I just hope it doesn't melt again

Blower motor control module probably , but without testing that's just a guess . Do you know how to do automotive electrical testing ? Testing B+ to the module ? Do you know where the module is ? You can find a wiring diagram here , http://www.bbbind.com/free_tsb.html There is a fuse for the blower motor in the I/P fuse box , HVAC blower 10amp ,

replace the A/C control head... very simple to do. Pop off the dash panel and pull the control head out... unplug the 3 harnesses and there you go.
