A blower motor may shut off immediately after startup due to several potential issues. Common causes include a faulty blower motor resistor, a malfunctioning relay, or a problem with the wiring or connections, which can lead to insufficient power supply. Additionally, a blown fuse or a short circuit in the system can also cause the motor to stop running. It's important to diagnose the specific issue to ensure proper functionality and safety.
Start by checking the Audi's blower motor fuse. Check the blower switch, resister, and lastly, check the motor to find the problem.
Yes, a bad capacitor causes blower motor to become slow or stop. Since bad or shortcapacitor will make the surge of current and tripping of circuit breaker.
Check the fuse and relay to start. If these are ok, then check the blower switch, the resister, then the blower motor itself.
when motor stops, tap on motor and see if restarts. if it does replace motor. there is a bad spot on the armature. if not check the blower resister.
Start by checking the fuse. If the fuse is good, apply 12 volts directly to the blower motor. If the motor runs it is good. Check all the wiring for loose or burnt wires. If all this checks out, then the Blower Motor Resistor Pack may be defective, or the blower motor speed switch itself.Start by checking the fuse.

Could have just overheated
check blower motor fuses and if Ok GENTLY tap blower motor with a/c turned on should start back up if so it indicates a bad armature in the blower motor and is due for replacement soon, if it does not start back up, it means either a short has occurred in the wiring or it is a dead blower motor
because the blower motor is no good, for some reason it get damp in the blower motor chamber, and slowly the speeds start to go one by one until you just have high.
To change the heater blower on a Seat Leon, start by disconnecting the vehicle's battery to ensure safety. Remove the glove compartment to access the blower motor, which is usually located behind it. Disconnect the electrical connector and unscrew the blower motor from its housing. Replace it with the new blower motor, reassemble the glove compartment, and reconnect the battery.
An HVAC blower motor stopping intermittently often indicates overheating, triggering a safety shut-off. Common causes include a dirty air filter, blocked vents/ducts, a failing run capacitor, bad motor bearings, or issues with the control board or limit switch.
Check the blower motor resistor/relay pack usually under the hood connected to the blower motor. You can start by using a multimeter and see if you are getting voltage to the blower motor electrical connector. It should read between 12 and 15v. If not then most likely the resistor/relay need to be replaced.
There are a number of sites you can go to and purchase a blower motor for your car. I suggest checking Amazon, Ebay, JC Whitney and carpartkings to start. I am sure you will have no problem finding a replacement.
