2005 Toyota corolla blower motor stopped working while I was driving, then started again..anybody know why?

Question

I was on my way home in the car Friday and just out of nowhere the blower motor stopped working, no sound, no air coming out the vents, no nothing, drove home about 20 miles and it didn't start working again....ok, had to go out Saturday night and move the car because a storm was coming and I had left the switch on and when I put the key in and went to start the car the blower was working....i hadn't hit any bumps in the road when it stopped working or before it started back working so I'm pretty sure it's not a loose connection but I'm not sure what to think about it...any suggestions on what might have went wrong? Don't wanna go and buy a new blower if I don't have to......the A/C and air recirculation lights came on when I push the buttons to turn them on while the blower wasn't working and they are still on now that it's working again (just trying to provide all the information I can think of so I can try to find out the problem and not spend money I don't need to)

Answer 1

Get a can of GUNK ORIGINAL ORANGE engien cleaner and hti the DIY car wash! IT MAY be a short in a harmess, so keep thigns CLEAN! Do this with ENGIEN RUNNING! CLean EVERYTHING and focus on the BLOWER MOTOR that is usualyl under the WINDSHI#ELD ina case! CLEANt eh BATTERYA s corrosion here can cause this as well! GOOD LUCK!

Answer 2

Might be the mouse living in there got too hot or too cold and unplugged it for a few minutes. Usually this is an early warning sign that the blower motor is about to die. Maybe this year, maybe next year? If it was set on one particular speed, and it works fine on other speeds, then the blower speed switch might be boogered up. 

Answer 3

When my 1998 Corolla did like that, I replaced the blower. Today, years later it's working fine. 

Answer 4

The brushes in the blower motor are worn down which causes less spring tension on the brushes. next time it happens try hitting the blower motor housing while the blower is turned on and that sometimes gets it working again. time to buy a blower motor and put it in. Advance Auto has good prices on blower motors which fit well.

Answer 5

Loose connection, broken wire, defective switch.

Faulty motor.

Answer 6

Let's start with some mathematics: 



2021 - 2005 = 16 years old 



That's beyond middle age in a car.  It's old age.  DC motors have carbon brushes that wear with use.  There are also bushings in the motor that wear with use.  With short brushes and a sloppy shaft your blower motor could be at the end of its useful life. 



There is also a blower speed switch and voltage dropping speed resistors.  All these electrical things could also have an age problem. 



P.S.  You wrote: 



Don't wanna go and buy a new blower if I don't have to...... 



This is humorous!

Answer 7

Intermittent failure. Blower motor or resistor module could be dying.  Fix it when it finally stops working. 



When it stops working, remove the blower assembly and connect the motor directly to the battery.  If motor does not run, the motor is bad. Get a new motor.   If the motor runs, the blower circuit has a problem.



"i hadn't hit any bumps in the road when it stopped working or before it started back working so I'm pretty sure it's not a loose connection".  Good mechanics never assume.  They test, find the evidence and check if their assumption is correct.  Not doing so will lead to bad diagnostic results.  Good luck.



Watch a very good mechanic troubleshoot and fix an intermittent blower problem.
