No heat or ac

Depending on the year , make , and model you have, most HVAC systems have a blower motor fan resister, usually located near the blower motor, check for power and ground at the fan resistor plug connector and make sure all connectors are in good shape, and not melted, or you will have to replace the fan resister pig tail as well.

My 99 jetta isn't blowing any air at all when I turn the ac on, or even the fans.

if I am understanding you right the fan isn't blowing anything. this could be a couple of things it could be a blown fuse, a bad relay, a bad switch, a bad fan motor, or a bad wire. I would start with checking the fuses and relay if they are all good I would see if there is power to the motor when it is on if there is power it is ether a bad motor or bad resistors if your fan runs on high but nothing else it is probably the resistors if nothing works it is probably the motor. if there is no power at the motor when there should be I would check for power at the switch if there is power going into the switch but no power coming out of the switch the switch is probably bad. if there is no power going to the switch you may have a brake in a wire if there is power coming out from the switch but no power at the fan you may have a brake in a wire if you suspect a brake in a wire you can test the resistance going throw the wire by setting a dvom to resistance and touching the positive lead to one end of a wire and the negative lead to the other end of the same wire high resistance bad wire no resistance good wire make sure there is no power going throw the wire when you test is though or it could throw off the test.

Yes,could be your blower resistor is bad,it's right next to the blower motor,it controls the blower motor speed,easy to replace.

Some cars have a thermostat that tells the fans when the water temp reaches a certain temp then the fans start. Or the relay that starts them could be bad. You may find the relay and switch it with another like it and see if that works.

The car is overheating the fan only turns on when the a/c is on

Look for and find the sensor that turns on the fan. You can replace the sensor or test it. Testing involves suspending the sensor in boiling water and measuring the resistance. When cold, the sensor should have high resistance and should be very low resistance when the water is boiling.

If the sensor is OK, check the relays that control the fans. You may have separate ones for temp and AC which is why the fan comes on when the AC is on.

Cooling fan only works when ac is on

You will need to check the fan relay, fuse and temp sending until The fan is turned on automatically when you turn to ac and defrost. The rest of the time it is controlled by pressure. I doubt it is the fuse because it is working on ac. Good news is that you can still get heat just by leaving it on ac but putting your temp all the way up until you find the problem. (assuming you are in an area like I am where it is getting coooolddd out there.

Hoe this helps.

AC Fan Motor Goes Off and On

There is a wire connector repair kit available at your local dealer. You may also need to replace the resistor module due to the connector being melted in the cavity. The heat is a result of a loose connection (high resistance) that eventually melts the connector to the module. Hope this helps.

Hi. here are a few steps that will help you troubleshoot this fan issue you are experiencing.

Step1 Check for broken wires or loose connectors around the fan circuit. Inspect connectors at the fan motor, relay, sensor or heat sensitive switch, and the Electronic Control Module (ECM)--your car’s computer control system. Also, make sure to check for a possible blown fan fuse. These are common and overlooked troublesome spots that may cause a fan to fail. Step2 Run and bring the engine to warm temperature. With the engine running, use a voltage test light to check for power to the motor fan. Be extra careful and make sure to keep your hands and tools away from the belt, fan or any other engine moving parts. If voltage is reaching the fan motor, the test light should glow. Step3 Turn off the engine after you see the light glow. Apply direct voltage to the fan motor from your car battery using a pair of spare wires. If the fan fails to operate, replace the fan motor. If the motor operates, your problem is in the motor connector. Step4 Locate the heat-sensitive switch or heating sensor if the fan motor operates with direct voltage and the test light did not glow. You should find the sensor in the radiator, engine block, or thermostat housing. Step5 Measure the resistance across the heating sensor with the multimeter. With the engine at cool temperature (engine off), it should register infinite resistance; with the engine at warm temperature (engine off), you should read low resistance. If both readings state infinite resistance install a new heating sensor, that’s the cause of your failing fan. Step6 Check the action of the fan relay if the heating sensor is registering variable resistance. Your service manual should specify the power and ground wires according to color codes and the proper way to test it. If the fan relay fails the test replace it with a new one. Step7 Check the connections going to the ECM after you determine the fan relay is working properly. If you find broken wires or loose connectors, make the necessary repairs. If you suspect a defective ECM take your vehicle to a service shop for a computer analysis. In most cases, the ECM is rare to be the cause of a failing fan. The above steps should take you to the root cause of your problem and help you fix the cooler fan.

Please rate and god bless.

Fuse blows on heat/ac

start with the obvious... you have a short circuit... i presume the fuse you have to keep replacing controls the fan. look under the dash near the fan and look for the resister block that controls the fan... you won't see the actual resisters but you will see wires that plug into the side of the duct work for the vents.... remove the two screws holding that block in and check the condition of the resister block. while you have the part out and unplugged you can easily test if the short is there by putting to fuse back in and seeing if it blows again.
