Question about 2008 Mercury Mariner Hybrid

1 Answer

Cricket-like squeaking sound coming from passenger-side dashboard. Does not vary with speed, road bumps, fan/AC speed. Mercury tech says it may be the "actuator," and that it would cost about $500 to repair. There's no sign of anything malfunctioning, just the squeaking/cricket sound. Can I find a part online? Can I do the repair without highly specialized tools? Should I worry about it at all?

Its likely the fan motor fan is rubing on the plastic houseing or something fell down into the defroster vent . You could try to realign the motor from under the hood its on the fire wall on the drivers side . Try loosening the nuts that hold it to the fire wall then turn the fan on and shift it around see if it stops if it dose then tighen it back up . If not you could remove the nuts and pull the motor uot and stick your hand inside the housing to see if something did fall inside . Idon;t think you need any new parts the fan motor isn't old enough to have a warn bearing issue unless the fan cage is cracked but thats is not an expensive part and farly simple to replace

    My Mercury Mariner Hybrid has this same noise. It is not the fan motor because as the original post points out the noise is constant and does not vary with engine speed nor fan speed. I am suspecting there is a pump to circulate coolant that needs a drop of oil, I have not had to to investigate.

Mercury Mariner Hybrid with "Cricket" noise in dash

Ianswerd this question be for and am adding a coment. Iv'e read your coment something must change with the noise i mean fan control knobs or air flow through a spicfic vent any thing that makes the noise change must be related to the noise because you don't have the noise when the vehicle isn't running . It could be related to a vacuum leakall of the accuators are vacuum motors but the noise is more like a hissing sound . And if you do in fact have a problem with one of the accuators witch is possibale but would effect at least one of the vents inside of the cabin and would effect engine porformance do to a drop in engine vacuum witch should make the Mil engine light come on.I wish i could hear this noise for my self . Im sure i could tell you more Dask boards are rather complex and diffacult to disamble on most newer vehicles now a days do to air bags and sensors and high tech robitic assambly methods use when the vehicles are put together and ounce they are taken apart they always make noise squeeks and rattles after that. SORRY i could'nt be more helpful but the noise is all you have to go on to diagnosis the problem

When the ac is on my 2004 mercury, no air comes through the vent. what is wrong ?

It sounds like the blower motor is out or has lost power. First, check the fuse. If that's okay, check the speed controller. The blower motor resistor pack/fan speed controller is in the engine compartment near the receiver drier at the passenger side rear of the engine compartment.

Creaking, squeaking sound going over bumps and uneven road surfaces and when turning wheel sometimes on a 95 Merc. Mystique

jack up the front of the car so both wheels are off the ground.
turn the wheels side to side,and listen for the noise.
it could be ball joints or stabilizer links.
there are after market ones available with grease points on them.
