Blower motor working intermittently?

[ksjdan]

Ok so until now, i thought my 87 euro had a bad blower motor or something. The blower never kicked in when I tried. But today, when I turned the heater on, it actually worked! Then it stopped, then it got weaker, then it was ok, then it stopped, then it worked again... blah blah. What might be causing the blower to work just once in a while?
Also I tried searching but didn't come up with any positive results..

Almost new alternator and working battery.

The resistors go bad. Does it work on full blast?

[estoguy]

Sounds like resistors.

Check the resistor and the wiring and connector to the blower to make sure it's firmly connected and there are no damaged wires.

I checked the motor itself. Its pretty seized up. Gonna need to replace it...

Had same problem. After starting the car first worked, then just got weaker and make some noise, and then died. And again started working and again same the same progress. For me it was the old motor. Replaced it and now worked good. Didnt saw any point to put some used motor there. New one was just about 80Eur.

Replace the associated fuses first. Old fuses can give intermittent power.

I tried a new fuse and relay k7 (i believe). It didnt solve the problem.

A new motor will solve your problem. While you're at it, order a new resistor as it's only 20 bucks. I'm dealing with this in my car as the used motor I installed is starting to go out
