Most units are one unit. Motor and squirel cage. A machine is used to press the cage onto shaft. Otherwise shaft bolt should have hexagontal nut end if it is removable.

Rattling noise from under glove box when fan for A/C or heat is turned on is it the blower motor or the fan?


Your blower motor and squirrel cage (fan).

more then likely it is your plastic squirrel cage fan under the dash.
they are made of plastic and over time the lock nut or screw comes a bit loose and the plastic collet on the fan wears out allowing a lot of play between the motor drive shaft and the fan .


Or you may have had something fall through your defrost vents on the dash and down into the squirrel cage housing

Replaced blower motor but there is no air coming from vents. What could the problem be?


Assuming the squirrel cage is attached to the motor shaft, my guess would be a blend door problem.

Fuse for heater keeps blowing in my 1999 Chevy blazer. Any ideas?


This would suggest a bushing on the shaft of the blower motor is worn and causing the motor to have to pull too much current to run properly. You should replace the blower motor or recondition it so the squirrel cage or "fan" portion of the blower motor turns freely with no significant resistance.

Hi, my 1998 dodge durango front AC/Heater blower motor run on and off, after the fan shuts down and stops running if I reah under the dash and hit the plastic fan housing it will start-up running but it...


If you can hit on the blower motor housing and the motor starts, your brushes on the motor are bad and the blower motor needs to be replaced. Used tested unit $30.00 at a junkyard. New rebuild $54.00.

Many posts have stated that the dash must be removed to replace the blower motor. It can be done without removing the dash. I know as I replaced the blower motor on my kids 99 Durango last night but it took about 4 hours. Now that I know how to do it, it would estimate 2 hours.

Remove glove box by opening glove box all the way. Press inward on the both sides of the glove box to allow the rubber stops to clear the catches and lower the box The two outer hinges (plastic) will come off by slightly twisting the glove box upward leaving only the center hinge (plastic) in place. Reach in and push down on the hinge to pull out glove box. Set aside.

Remove side trim panel by pulling back carpet and remove one Phillips screw. Remove panel by pulling back on upper portion to remove clip from frame, then slide forward to remove from lower plastic trim.

Use 1/4" nut driver or socket to remove two screws holding vacuum canister on lower right side of blower shroud. Remove two vacuum hoses noting which hose goes to which side of the vacuum canister (both were green in color on my Durango). Disconnect connecting rod from vacuum canister to vent control by removing lock washer (you may be able to get away with not removing the rod, but the plastic "fin" may break if you stress it while removing the blower shroud.

Use 5/16 nut drivers/sockets with extensions to remove the blower shroud hex bolts. The hex bolts are located in several areas around the shroud (use your finger to follow shroud edges to locate all 8). Some of the hex bolts are very tricky and may require odd positioning of your body to locate and remove them.. I also put several extensions to use in order to reach the various hex bolts. Once the hex bolts are removed, pull the plastic blower shroud down exposing the blower motor squirrel cage.

Remove two of three hex nuts holding blower motor in place. Loosen the third one and the blower motor should come free. I was not able to remove the squirrel cage from the old motor so I broke the squirrel cage allowing me to expose the wire harness and grommet that went through the back of the shroud.

Feeding the wire harness back through the assembled wall appeared to be a real challenge, so I cut the green and black wires at the motor for splicing into the new motor later. Remove the motor and broken squirrel cage and throw the dam thing away.

Remove squirrel cage from new motor by removing retention clip with a pliers. Pull off the squirrel cage carefully by applying WD40 (or other lubricant) to the shaft. You may have to place two large screw drivers or other pry bars underneath the squirrel cage equally across the underside of the squirrel cage slowly prying up the cage. I accomplished this with a helper to hold the motor in place to allow equal pressure from both pry bars.

Cut green and black wires on new motor leaving enough wire to work in the tight area of the motor housing. Strip wires from old harness and new motor and apply **** splices for green to green and black to black. Add electrical tape for extra mechanical strength and insulation.

Place new motor into housing and secure the three mounting hex nuts. Turn on key and run blower to make sure it works. Install squirrel cage and retaining clip on motor shaft. Run again to make sure it works.

Install the balance of the items in the reverse order you removed them.

Good luck!

1990 Mercedes 300E.How to Reaplase Blower Motor?


This is a 124 chassis model.The blower motor is under the cowling just in front of the windshield.You will need to remove the plastic pieces in front of the windshield and the wiper transmission.It will have squirrel cage fans at each end.If you are not experienced with removing these fans,use extreme care,because plastic gets brittle with heat and age.You can use a hairdryer to warm to plastic hub for easier removal.When tapping the motor shaft free of the cage,keep it evenly supported.Make sure not to drive the cages onto the new motor shaft too far.They will contact the housing.Replace broken fans-they vibrate badly.Blower motors with new fans installed are readily available for extra bucks.

What part makes a clicking noise on the blower


Most GM vehicles have little flaps or doors to redirect the air near the blower motor. If that gets out of place or falls down it will rub on the squirrel cage of the blower fan. Some older cars have insulation in that area that might come loose and rub on the squirrel cage. The insulation sometimes is covered with a stiff paper. Cutting away the stiff paper with allow more clearance.

Noise coming from my blower sounds like something is loose


HI.The blower fan or squirrel cage is rotated by the blower motor shaft, thus, forcing air through the heater core or A/C evaporator core and into the passenger compartment. it is housed in the blower compartment shroud. If the motor shaft becomes unstable, this will cause the cage, or blower wheel, to rub against the shroud, or housing. This will cause the noise you are hearing. The shaft screw may be loose, or the shaft, itself, may be faulty as well.

In most cases, replacing the blower wheel will correct this issue.It would be wise to inspect the blower housing for any loose mounting screws before replacing the wheel.
