Question about Cars & Trucks

1 Answer

I have a 2005 Mercury Sable. When the A/C is on and you're outside the car you can hear a rattling/grinding type sound under the hood. It's not loud and probably wouldn't be that noticable to anybody who wasn't familiar with the way the car sounds. A/C seems to be working fine. Any ideas?

In most cases the noise is the bearing for the ac compressor clutch. Once the clutch bearing fails, the serpentine belt will be lost.

SOURCE: very loud "rubbing " sound when driving only

you did damage to the wheel bearing i bet it sounds like a airplane sound. also if you steering wheel is off 7"then have front end aligned because this will destroy the tires and they will make noise.

SOURCE: 2005 nissan murano sl, with rattling sound when accelerating

I recently experienced the same symptom with my '05 Murano and it was not a fuel problem. The dealer listed the cause as dry axle splines and replaced both front drive shaft assy's. Note that this was done as warranty with no cost incurred by me.

SOURCE: Engine rattling

It sounds to me like you have a broken serpentine belt and the noise is coming from it rubbing on the crank.Shut the car off and look again and if i'm right you need to pull it out and then get the new belt install asap.If you do have to drive the car just remember that without a belt the car will not recharge the battery and it will over heat quickly so just take it far enough to park it in a safe place.

Mercury sable 1996 changed fuel filter had brown gas in it did this ruin fuel pump. Can hear pump when trying to start car

Most likely the fuel pump is ok, but there is likely air in the fuel line that you need to bleed off under the hood.

It is possible that the fuel pump went bad, and the way to know is to check the fuel pressure (same place you bleed it under the hood). The fuel pump is in the tank, so it's a real pain to change.

Wipers will not work on mercury sable, 2005

Go outside and get close to the wiper arms and listen for a grinding sound, which means the gears are stripped. Also, go look under the hood to see if the arm mechanism has come disengaged from a loose bolt or a bolt that fell out. Also, check the fuses under the dash to see if any have blown. If all that looks fine, then you may need a new switch in the wiper arm assembly.
