Why did you remove the resistor for?Was the blower not working correct?Is that the same resistor?You can go to Autozone and get a resistor and install,if it doesn't fix the problem,take it back.,check power going to motor.Check fuse.

SOURCE: 2005 GMC Envoy SLE blower fan speed #5 is not working

More than likely this should just be your resistor. You have different sized coils on the back of your resistor for all the different fan speeds. if one of them burns out or breaks then that certain speed will not work.

SOURCE: BLOWER RESISTOR BAD FAN ONLY RUNS @ HIGH SPEED

Chevrolet 2004 TrailBlazer

Look next to the blower. You can remove the panel under the passenger side. Go through the glove box and move it down out of the way to access the electrical connector. Then remove two bolts and the electrical connector.

SOURCE: NEED TO REPLACE BLOWER RESISITOR. FAN ONLY WORKS ON HIGH SPEED

Under the dashboard on the passenger side you will see the blower motor. Near the blower motor inside the air duct is the resistor. It should be held in place by two screws. Hope this helps. Good luck

SOURCE: Blower motor vent selection switch not working

the hvac selector switch in the dash may be the problem.You need to remove the switch and look at the connector on the back of switch,see if there are any burnt wires at the connector or switch.It's all electronic and the switches have been known to burn out on this and other model.

Why does'nt my heater fan work?


There could be a number of reasons. Fan is bad, fan area in box is so clogged it doesn't allow fan to spin, a bad switch at instrument panel, a bad resistor, bad connections. I would start by removing the fan. I believe you will have to go in behind the glove box. Remove the fan and check to see if it works, it may be fine if bad replace. Check inside of box for leaves and any other kind of clutter that may be preventing fan from spinning. Check wires to fan for mouse damage. Mice can take there toll on a cars wiring. If all is well so far check the switch in your dash. Switches are funny, some last a life time some don't. I believe you will find your problem, following these steps. GOOD LUCK FRIEND.

1992 buick le sabre blower motor resistor location


If your Buick has "automatic HVAC" (you set a temp and it stays there) you do not have a resistor but a electronic controller. The common failure on these is the blower stays on when the key is turned off. In either case, the part is usually located on the engine side of the duct work. it will have wires/connectors and be in the airflow of the blower.

98 buick heater stop working


Its faulty blower motor resistor. The low and medium speed on blower motor is controlled by resistor and its actual speed is high. So because resistor is not working, blower motors actual speed which is high is working.


It can be faulty blower motor or faulty blower motor resistor. Get the blower motor inspected. If it's faulty it has to be replaced.

My heater fan does not come at all on any speed


Sounds like a bad blower motor assembly, if it was only working on high speed then it would be the blower motor relay (this is a default setting so the defrosters will always be able to work, hi speed actuallly bypasses the blower motor resistor), but if you have no speeds at all then the blower motor itself is your most likely culprit. Hope this helps...

Location of low speeds heater fan fuse & switch. I do not have a owners manual.


the switch is on the dash with the other a/c controls. does the fan work at all? high speed OK? but the lower speeds dont work? if any speeds other than high dont work, replace the blower resistor.

1994 Buick Lesabre blower runs on all speeds


If you are referring to the AC blower, you may want to check on the fan switch. It could be caused by bad contacts or loose connections. There is also a resistor if you would trace the wiring of the switch to the evaporator under the dash. Check if it is still intact. It may be partially be burned.

On my 1999 Buick LeSabre the blower fan does not work at all


How about checking voltage into & out of resistor for difference. Some swear by high only when resistor goes, but in past I have had intermittent use of other speeds before it finally went & I had high only.

Blower fan comes on high only after 5 mins.


Maybe a relay which is under the blower motor under hood or a blower control module or resistor depending on the ac system you have.
