Todd... No concern for a blower motor that gets power and doesn't spin?

Thanks for the help,yeah i replaced the blower module under the maxi fuse center. And there is no air coming from neither vents defrost floor bi- level. And when i had taken it to the mechanic he said on my car theres only a blower module no resistor? Makes no sense he said because i have the automatic control. But u said its located in the dash where the actual climate controller module itself is (where that resistor would be located.

He also said there was power at the motor connector. This kinda leads us in a circle..power at motor, motor tested good.. How'* that possible you ask?


The mechanic is correct, you have no resistor on your model.

There is a head unit... the one you adjust the temp on. Rarely ever has an issue.

There'* the HVAC programmer under the dash, also ...rarely ever has issues.

There'* the blower control module.. this is in the blower air box under the maxifuse panel in the engine compartment. This does go bad and will cause the blower to not function because it won't feed the blower power.

There'* the blower motor. If you have power at the motor and the motor does not start up while in the car..but does work on a bench.... your motor is bad. A slight boost in power can fire up a bad blower motor..this can cause a false positive for a test.

The last one is what I was thinking. You said it tested good, you also tested power in the car at the motor connector and had power. If this is the case..blower motor. If you have no power at the motor.. it'* usually the module.

My wifes 95 SSE W/ACC has a blower resister......it went bad years ago and I replaced it and that fixed the problem.

Oh well.

If your have it on ac or heat, no air comes from ANY of the vents, no matter the selection??? id say prolly the blower motor, which case you need to put it to a straight power source and check to see if the motor works, if it does then you prolly need the blower resistor replaced

if your not getting ANY air, it would be the control unit (dash unit), a wiring problem, the blower motor resistor, or the blower motor itself. start with the motor itself and check to see if it works at straight power

I have the same problem with my 98 A/C-Heat. Compressor clutch engages and I can hear the actuator arm move but I have no blower fan turning. Do I have a fuse? Relay? Resistor? And where are they located so I can test them? Nothing under the hood is marked. How much of the engine upper end do I have to remove to pull the blower fan? Not the turbo I hope.
