Blower won't run

If the blower motor runs in the off position, check the fan relay.

Someone will need to check the fuse for the blower, then the blower motor and the resistor.

If you have bypassed the board and the motor runs then you are correct the fan control must be replaced.

It's the fan motor. A relay problem would cause the motor not to run at all.

Have you replace the heater blower motor? It sounds like it is shorted.

Hello there and welcome to fixya
The most common problem with these are the motor or the motor bearings or rollers
and next is clothes getting caught between the drumb and the shell of the unit
Here is some troubleshooting help for you listed below
Motor If the dryer motor only hums when you press the Start button, the motor may be burned out. Here's how to test the dryer motor: Remove the belt. Check for obstructions in the blower fan housing. Manually rotate the shaft of the motor. If the motor is very stiff, or impossible to rotate manually, and the blower fan housing is clear, you need to replace the motor. If the motor rotates freely, run the motor momentarily with the belt removed and the blower in place. If the motor runs fine with the belt removed, there may be a problem with the idler pulley or the clothes drum. Try to rotate the drum by hand. If it is very difficult to move, correct any problem with the rollers or pulley, and then reassemble the dryer and try it again. If the motor hums but doesn't rotate on its own even with the belt removed--yet you can turn it freely by hand--you usually need to replace the motor

maybe it has tripped off on high pressure, as you have have said the fan is not turning so will cause high pressure. now assuming the problem is the fan is not running than check the condition of the condensator /capacitor for the fan motor. if the motors winding is still good replace the capacitor and try it ON.

Hi,
Sounds like you need to replace your evaporator blower motor capasiter, it is located on the houseing of your blower motor, easy to do , but be carfull, they hold a charge and can shock you.
remove the two wires and replace like for like, check operation. If problem still exists, you need to replace the blower motor.
This should help.

Hi,

If you're referring to the heater "FAN" running continuously, then its likely to be your blower motor resistor.

The heater blower motor (under the dash) has constant power supplied from the battery, but is controlled by the blower "resistor" - usually mounted on the blower motor assembly. If one or more of the blower resistor coil wires are faulty, the motor will either not work on one of the fan settings, or will constantly run by itself.

First check the 15 amp HVAC fuse located in the main fuse block inside the car on the passenger side of the center console, under a cover. If the fuse is good, then the problem may either be the HVAC blower switch (which is the fan blower selector switch), the fan blower motor resistor, or the fan blower motor. An auto repair manual will explain and illustrate for you the steps on how to check each of these components.

Even after pushing the ac light switch on, the fan blower selector switch has to be turned on as well (working) because it provides an electrical path to the positive side of the battery to complete the circuit and turn the ac light on. What the ac light switch does is provide the electrical path for the ac compressor clutch to come on through the ac control relay which is controlled by the car's PCM(computer) when you want ac, but the ac light switch still needs to run through the fan blower selector switch to receive its power. You can turn on the fan without the ac light switch because it gets its ground path(negative) from the blower motor. So the blower motor has to work in order to provide a ground path for the fan blower selector switch to be functional. You could have a faulty blower motor which is why no air blows through the vents. The fan blower motor is located inside the car on the passenger side underneath the dash at the bottom end of the glove compartment box. You'll see it. It's right above where a person rests their feet on the floor. Therefore, if your 15 amp HVAC fuse is good, check to see if you have voltage at the blower motor connector. Unclip the connector and with the ignition on and the fan blower switch moved to any one of the first 3 selections, check for voltage using a multimeter. The voltage will vary because there is a blower motor resistor. Voltage should be higher on setting 3 than 1. If you do have voltage at the blower motor connector, check for a faulty blower motor. The auto repair manual will tell you how to do it using jumper wires.

It's normal that your car is running hot because the radiator fan works in conjunction with your ac compressor. If the ac is on, the radiator fan will be on and therefore the engine coolant temperature will stay in it's normal operating range. If the ac is off, the radiator fan will stay off as well and the engine coolant temperature gauge will begin to rise and show pretty hot (especially at idle). It will do this up until a certain degree then the radiator fan should turn on thermostatically and stabilize the temperature. It's scary and I know what your saying because it does that to my car if my ac isn't on. Don't worry it won't overheat.
