Question From pettitd1 on blower motor quit working

My 97 Buick Lesabre, 3.8 engine 120,000 miles

I shut the car off to fill with gas. Restarted car after filling and the blower motor failed to work. No prior problems. No noise, no prior problems. Acts like a fuse is blown. I checked all three fuse locations, the owners manual does not show a blower motor fuse, HVAC fuse is not blown. Is there a breaker or relay, and where is it located. thanks for any help you can give!! thanks dan

Response From Discretesignals

automatic or manual ac?

Response From Discretesignals Top Rated Answer

Probably would be a good idea to first check for power and ground to the blower motor at the blower connector. Should be easy to check on that design.

Sometimes for a quick check to see if you have a blower motor brush problem you can also try wacking on the blower motor housing with it turned on high. If the blower takes off when you wack it, you need another blower motor.

Response From pettitd1

ok finally made it home, was out of state traveling, i rapped on the motor, but nothing happened, i just checked the voltage at the motor and there is none, i also checked the resister with all the springs on the back of it mounted in the air box and it looks ok.....so as of now, it is powerless with the key in the on position and control on high, any suggestions where to look next????

Response From Hammer Time

Check the fuses indicated at the top of the diagram.

Response From pettitd1

i checked all three fuses, they are good; the compressor is working, everything works except the blower motor

Response From Hammer Time

Check the Blower Motor speed relay.

I would try swapping it with the horn relay.

Response From pettitd1

can you instruct me on how to test it please, i have a multi-meter

Response From pettitd1

swapped the horn relay with speed relay horn works fine, no blower yet; i see there is a blower relay also, but there is not a relay to swap with it has five pins, is there any way to check it???

Response From Hammer Time

OK, now you need to go back and redo all your testing because you have done something wrong. These results aren't possible.

Response From pettitd1

I took the 5 prong blower relay out and replaced it with a new one and, THE PROBLEM IS FIXED. I took a chance because everything else checked as good. Thank you for all your help and taking the time to show me diagrams, could not have done it with out your help. I told the guys at Auto Zone about CarJunky.com and highly recommend its use.

thanks again
Dan P

Response From Hammer Time

Not possible either. The way this is wired, if that relay was bad, you would have had all speeds but high so your answers are still wrong.

Response From Discretesignals

Unless the relay contacts were fried. Open up the old relay and check out the contacts.

Glad to see you got your blower working again.

Response From Hammer Time

Unless the relay contacts were fried.

Yeah...... right.......(sarcasm)

Response From Hammer Time

Swap it with the horn relay if they look the same.

Question From FOSE88 on Cavalier Blower Motor

I have a 2002 Cavalier with 51,000 miles. The blower motor only works in positions 3 and 4, NOT 1 and 2. Is there a way to tell if my problem is with the switch or the blower motor? I wouold prefer to not replace both.

Response From DanD Top Rated Answer

The problem is likely the blower motor resistor; these resistors have been a problem on GM’s for sometime now. You’ll find it under the right side of the dash on the heater box housing, close to the blower motor. It’s held in with two small bolts.

Question From eyob07 on blower motor

Hi everyone is it hard to replace a blower motor on Volvo C70 2007

Response From Discretesignals Top Rated Answer

6.6 hours labor + $273.00 for the blower.

Response From eyob07

thank you, the problem is the blower motor comes and goes, like when the car is on a rough road the bower works and after while it quiets, I wonder if is this is a connection problem or internal problem of the blower what do you guys think, thank and God bless you all.

Response From Hammer Time

Could be either one. You aren't going to know until you actually check it out while it's dead.

Response From eyob07

Hi everyone I just need to know the location of the blower resistor, a picture will be good thank you like always.

Response From eyob07

thank you, well I,m not a professional I,m just an enthusiast so don't expect me to aproche problems that way, I want to know once I took the motor and find out to be ok the next step will be to check the resistor

Response From Discretesignals

This climate control system is a little complex. The climate control module (ccm) talks to the central electronic module(cem). Based on the inputs the ccm receives it tells the cem how fast it wants the blower to run. The cem sends a pulse width modulated signal to the blower driver to regulate the motor's speed. There is no conventional blower resistor. The blower's speed is controlled by transistors built inside it based on the duty cycle of the signal it receives from the cem.

Maybe you should let this one go and send the person to a professional. You don't want to spend 7 hours ripping the dash out thinking you can just connect the blower motor to a battery to get it to work. It needs not only battery and ground, but it also needs a duty cycled signal to operate.

Response From eyob07

thank you very much and I will do like you suggested.

Response From Hammer Time

In all the responses posted here, not one even mentions a blower resister and yet that's what your looking for.

Response From eyob07

thanks and we will see what in there when I check it dead.

Blower motor only operates at 2 speeds

Question From nelsner9494 on Blower motor only operates at 2 speeds

96 Dodge Dakota

My blower motor used to work on the three lowest settings, now it only works on the lowest two and makes an odd noise at consistent intervals. Any ideas?

Response From Hammer Time Top Rated Answer

That could be a bad switch but more likely a bad blower motor resister located under the dash on the passenger side, next to the blower motor. The circuit should be tested before replacing any parts.

Response From Tom Greenleaf

? Never say never but usually the resistors when failed give you just high speed. Cheap enough usually and if easy enough I'd try one and make sure connections look good. Then move on for further diagnosis for switch or wiring issues if that doesn't solve it,
