Check for voltage at the motor , you have the correct voltage there the motor is probably bad.

Heater blower motor quit...need to find ground for resistor


I suggest you find your fuse/ relay center check fuses and try new relay, I think the relay is 75% at fault most of the time.
Blazerk from Altima forum suggest
Back probe the blower motor Blue/Yellow circuit and tap it to ground, if that doesn't make the blower operate, the blower motor/power transistor assembly is bad. When the blower motor does operate while grounding that circuit, the climate control panel may be faulty, repeat the test from the connector at the control panel to verify the wiring is not damaged. Also, When verifying voltage, Use the power and ground wires to the blower motor. Other grounds may give you faulty readings.

Replaced the resister and blower motor still nothing what next


Test for current to motor. If none you have either a bad fuse, bad switch or bad wiring. Nothing else left.

Why wont my a/c or heater fan come on?


When the blower works only on the high setting its usually a bad blower resistor which is right near the blower motor. now you say it would always blow high regardless of the fan speed setting that would indicate probably the climate control unit or a connector problem somewhere. finally it not working at all may be the climate control unit or connection went bad even further. it might have a blown fuse or a bad blower motor in addition to the climate control unit or connector problem .check for power and ground at the blower motor. the power is supplied from fuses and may have a relay also. the ground is supplied from the climate control unit and goes through the resistor to control the fan speed. good luck

My heater and AC blower not working. Please help


In the fuse block,under the hood on top of the fender. Locate fuse #35 it's 40amp fuse for the blower moter. If the fuse is ok,there is another
common problem you can check. The blower moter resistor assembly,
located under the dash on right side. With a 12v test light check for
power to the blower moter from the resistor. If you have no power to the
moter, replace the resistor assembly. If niether of these works, I'll need
to know if you have climate control or manual control hvac. And for some reason, the wheel base. long wb or short wb. to dig any deeper.
But I hope one of the causes I've mentioned will cure the problem.
Good luck.

Where is the blower motor relay located on a 1997 buick lesabre.


There are 2 relays for the blower. The low blower relay and the high blower relay. They are both located
under the hood in the center of the firewall.
The low will have 4 wires from it, one lt. blue and 3 brown. The high will have 5 wires 1 purple(to blower mtr.) 1 black 1 dk blue 1 red and 1 orange.
Also, the blower resistor is in the same area if needed. Hope this helps.
