20 Most Recent 2008 Mercury Mariner Hybrid Questions & Answers

Taking the vehicle to the dealer an having them run diagnostic's is your best bet .

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

dealer only ,try the spare key first though

The Wrench light is a Throttle/Powertrain light, if its shifting weird this may be a problem. It could be a few things. I would take it to a repair shop that deals in hybrid parts, maybe even a dealer. Here is a link that goes in-depth of the Wrench light. As the article says it could be anything from a $12 part to a $1,000 hybrid part. Some are getting this light do to overheating of the Hybrid batteries, hope this helps,

Smoke Test the intake manifold

When the Spark Plugs were replaced,
they may have over looked the intake
gaskets or damaged them

You either have a misfire on a coil that
isn't the one the code showed or you
have intake vacuum leaks & the lean
O2 Sensor Reporting.

I may have mis read what you said.

You have to replace all spark plugs,
look at O2 switching time ,then work
on the coil walking thing, with a new coil,
until you find the offender

You need to have the code that came for that vehicle. There are 2 places that you can look to find the code. Sometimes you can find a sticker in the back tailgate area it will be white and most of the time it is on the right (passengers) side. The other place you may be able to located is in under the hood most of the time it's on the drivers side firewall by the brake master cylinder. It will be a metal plate with 5 numbers on it like the sticker will have in the back if one is there. I hope this helps and good luck.

immobilisor has come on by the sound of it and for this its a dealer only job ,

replace the air and the fuel filters and check the drive belt on the engine replaced as ness, that is it.

you probably need a door latch somewhere. assuming you have under 36000 miles take it to the dealer for a warranty repair
