Blower motor stopped working

[rlewissni]

I recently replace the blower motor and the resister. it was working fine till on day it just stopped. what could be causing this system to fail?

fuse?
what model?
What resistor did you change - do you mean the regulator pack?

I changed the blower motor and the Blower Regulator. and it was working fine then one day it just stopped.... what could be the prob?

The mechanism is quite straight forward. The first thing you need to do is check the power feeds into the regulator. It should have an earth, a constant live and a variable switch live.
Assuming you have these, then check the feed out of the regulator. If there isn't one, it's the reg. If you do, it's the motor.
If the switch or constant live are missing then trace backwards - switch, fuse etc
