Hi!!
The part is called Blend Door Actuator, it is located on the passenger side under dash, behind glove compartment, on the blower motor housing, is held by two or three screws and has an electrical connector plugged into it. You can get a replacement at almost any auto parts store.
Good Luck!! A HELPFUL - 4 THUMBS - rating for this solution would be greatly appreciated. Thank you for using FixYa.

check that your tensioner pulley still has tight tension on it.

There are butterfly nuts inside the trunk right behind the taillights and the carpeting take those off and the taillight should fall right off and turn the light plugs counter-clock wise half turn and the light bulbs will come off

-Make sure Shift handle is in "park"-Make sure battery cable to starter is good connect (Tight)and Not corrosion.Try again

Pinging or detonation is normally caused from incorrect fuel mixture---timing or not changing gears when the load for the engine becomes excessive for the revs. Left unchecked it will damage the pistons. Use a higher grade octane rating fuel (give ethanol mix a miss). Have the ignition timing checked and corrected. and ensure that the auto is changing when it should be or change gears more often and keep the revs up.

Here's a link to your crankshaft position sensor,Here's the part.

The problem isn't with the oil pump. The oil pumps job is to move oil around the engine. What the problem is, the main and rod bearings are so worn out that it can't create oil pressure anymore. That's why you have a knock in the bottom end of the engine. The tighter the clearances are at the main/rod bearings, the better the oil pressure you'll have. The cam bearings also play a roll in producing oil pressure.

You need to check your fuses. When you jumped your car it could've blown one of them. They are usually somewhere under a cover in the viscinity of the driver's seat. You should be able to visibly see if one of them is blown. On the top where the number is (probably something around 5) there is a wire and if its not connected the fuse is blown and needs to be replaced. You can get them at any auto parts store.

disconnect the mass airflow sensor located between the air filter and the throttle body. if it runs better that way then the sensor has failed.if it runs worse that way, then check your fuel flow and pressure.I don't know which engine we're talking about, but if it doesn't have a MAF sensor then it has a MAP sensor which is hard to diagnose without a proper diagnostic computer, but you can see if the vacuum line going to it has fallen off or is cracked and leaking.Both sensors are quick reaction sensors and can be the cause of your symptoms.

Try YouTube, it's a lengthy deal that's better done with photos.

I seriously doubt it.The O2 sensors measure the amount of unburned fuel in the exhaust and would not be affected by water if you got them wet.The spark plug wires and coils would be affected.

did you already make sure the theft system is not triggered???? the security light will blink on dash, when the key is on. if blinking, email [email protected] for how to reset this.

if its a dealer intalled unit they can tell you how to disarm it.. if its an aftermarket unit then its a matter of disabling the power to the module control..

have you tried grease on the batteries nipples sometimes the cold can discharge the battery if you dont have any grease try petrolium jelly or vaseline etc

How about timing? How about the distributor and rotor? What about the timing chain?
