Sounds like the blower relay switch is bad. It's a small black square object, usually mounted on the firewall with two others, or in the fuse box in the engine compartment.

Blower motor 2009 saturn vue doesn't come on, fuse is good, what next?


DISCONNECT THE BLOWER MOTOR POWER LEAD. RUN A "FUSED" (20AMP) HOT JUMPER WIRE TO POSITIVE SIDE OF CONNECTOR,THEN TO BATTERY POSITIVE, THEN RUN A NEG. WIRE BACK TO NEG. AT BATTERY (TO INSURE A FULL CIRCUIT).
IF BLOWER WORKS...YOU HAVE A SWITCH,WIRING, OR FUSE/CIRCUIT BREAKER PROBLEM.NEXT CHECK FOR POWER INTO BUT NOT OUT OF SWITCH...IF THIS IS THE CASE THE SWITCH IS THE PROBLEM.

How do I determine if my my switch on my Blower motor is bad or if my Blower Motor needs replaced. Right now nothing works.


Disconnect the electrical connector from the blower motor itself. Then jump 12v tol one of the motor leads and induce ground to the other on the motor. If the motor spins, it's good. Then check to see that you are getting 12v and a good ground from the harness side of that connector that you detached from the motor. That will tell you if the rest of the system is working up to the motor.

Im trying to troubleshoot a non-funtioning blower


To test the blower motor run a jumper wire from the hot side directly to the hot terminal on the battery. If the motor is in good condition it should come on. If it comes on that may indicate a bad resistor pack. Since the resistor is an electrical part which is self-contained would probably be easier to change than to test. You should do the resistor pack first (before the switch) because it is the easier of the two to change out. If replacing the resistor pack does not fix the problem then you will need to replace the switch.

Front blower motor does not work at all with the heat or the a/c on the rear motor works fine. I have changed the relay and the fuse but it still doesnt work i wanted to know if its the blower motor or the...


There are the only three items remaining in the circuit. It could be Motor, resistors or on/off switch.
To test blower run a pair of jumper wires from battery to motor terminals and she if it runs .
Switch is easy : remove it from its connectors and jump the wires and see if it runs the motor.
Resistors your gonna ned shop manual fro to know the value of each speed so you can test them with an ohm meter. Good luck

Air conditioning and blower stopped working, all fuses checked good.Is there a common feed to these two circuits?


The answer is that there is dirt dust and fuzz built up in the brushes of the blower motor. Had to figure this one out myself. Remove glove box, carefully disassemble bottom of blower motor, remove brush cap and brushes clean up mess and reassemble. Not for a novice but if you're a thinker you can figure it out. Mine has worked every time since. The Pontiac guys had no clue wanted to replace motor.

Blower motor does not run, fuse good-resistor good- motor runs when jumped with 12 volts


check the wire going to the blower for power- test light should dim and brighten as you turn the knob from fast to slow (goes through the resistor). If good -make sure you have a good ground from the wire going to the blower.

Air Conditioner blower motor resistor was replaced 2 years ago when ac blower stopped working. Blower is not workinga again, i replaced the blower motor resistor (behind glove box) and still not working....


Motor is also energized by a relay. check that and also check that the motor itself is good by running a hot lead right to it. I'm sure you already checked the fuse and know the switch is good?
