Hello.
My inlaws have an 06 path. They have a basic hvac but the other day their blower motor stopped working. They've replaced the motor and resistor but still no power. Any ideas before the spend more money on parts?

There is power at the fuses under the hood and the relay is good.

I believe there is also a fuse in the interior fuse box related to the blower motor, was that checked?

Should be two 15amp fuses. Top left on interior fuse block.

Gotta find your SPECIFIC schematic ! Most blower ckts have at least one relay AFTER the fuse , some two.
A single relay usually kicks "ON" the whole shabang - power to "resistor" (Transistor= modern ver.'s) and blower.

Then the second relay (IF used) can be for DIRECTLY "shorting load side to ground " thus giving Max BLOW and thus saving the controller OR resistor to NOT deal with the highest current stresses !!
:rotflmao
I'm right now troubleshooting my daughter's car.

Tip: Locate and "expose" - Blower motor ,and ALL relays for Blower/AC . Now if & when NO-BLO try and give a good "Rap-A-Tap" with mallet or screwdriver handle to each of those componants. Relays may engage poor contacts AND motor may get "Bumped Out" of the dead-spot it's stuck in ?!?!
Ya see if ONE or more are culprets. :spitout:
