Hi!!

it sounds like when my boy stuck a piece of hard candy thru the vent. Either that or there is a broken fin in your blower.

In any case, the only way to find out what's causing the noise is to remove the blower from it's housing and visually inspect both.

to remove the blower just remove the blower motor, the blower is attached to it.

Don't forget to rate this post!! Good Luck!!!

Usually when you get a ticking in the blower motor the bearings are going and the fan blade is hitting the shroud it sits in. There is a possibility that a mouse/squirrel found its way into your heater box, I have seen that many times...hope that helps!

Loud Noise in Central Dash area, 2000, F-150,,Sounds like a fan hitting against a heavy plastic part.Starts around 45MPH.. I think its either air flow or speed causing it.


Have you checked to see if the heater motor is ok. Sometimes the newer ones have a bearing in the end by the plastic fan and the bearing will allow the fan to drop down and cause a loud noise when running. To check turn off the heater motor fan on the dash and see if the noise goes away.

When I turn the air switch on a sounds comes on like from the fan but the fan is turning if i turn the swith off the sounds goes away. where is the sound coming from?


could be the fan hitting or rubbing on the fan housing or something has fallen into the fan motor housing thru a vent such as a paperclip, coin etc. and the fan is hitting that object. correcting either problem requires the opening up of the fan motor housing.

Fan Blower Makes noise


Sounds like the fan needs to be replaced. But first, to check for obstructions, remove the carpet liner from the underside of the dash on the passenger side and you'll see the blower motor under the dash held in with three screws. If there's something obvious blocking it, remove it and reinstall the fan. If there's nothing blocking it, then you'll probably need to replace the fan. Any auto parts store, Rockauto.com or E-Bay will have the correct fan for your Grand Prix.

Sounds like the fan motor is hitting on somthing.

Take some chalk and coat the outside of the fan blade. Install it back into the truck and turn it on for a second. Take it out and see where the chalk like is inside the fan housing. make adjustments to anything it is hitting and/or replace fan if it is bent/damaged.
