You could be hearing the air compressor for the air shocks running. This would indicate an air hose cracked or fallen off the shock.

From where , any switch ? driver door switch or either passenger door switch . This is a very complex system controlled by modules (microprocessors) ?€¢ The driver door switch assembly (DDSA)

?€¢ The RRINMDL Fuse - 10 a Class 2 and Power Door Serial Data Links The class 2 and power door data circuits are both serial data links. The serial data circuits replace cables in the vehicle by multiplexing (time-sharing) data to and from each device over a single wire referenced to ground. If the power door serial data is lost, both the rear door module (RDM) and the passenger door module (PDM) enters the sleep mode. With the RDM and the PDM in sleep mode, no power door operations are possible. Your best bet is to take it to the dealer or an ASE certified repair shop .

parts store. there cheap. less than what you would need to buy for a temp fix. Hope this helps Mike

Idle speed is normally controlled by the idle air control motor. These units get dirty and fail, but can often be cleaned and restored to normal function. You will need to remove the unit to clean it, but be careful not to damage the plunger and seat. Use carb + choke cleaner and maybe a small screwdriver (carefully), then blow unit out with compressed air. Replace gaskets as needed. Also low idle can be caused by vacuum leaks, bad O2 sensor, clogged exhaust (cat converter), dirty MAF, bad coolant temp sensor.

Is the check engine light on/flashing? You may have a cylinder misfire causing a rough idle and poor hesitation like acceleration

sounds like the linkage is broken/disaconnected, under the hood against the firewall is the wiper motor assy, behind that is the linkage something must be broken/disconnected

The fuse box is located under the clove box you may need to remover the clove box door to have a good view

To start you have to run the codes from the stability control module, and once that's done then you can beging to look for the problem, only a tech II scanner can reset this module, also make sure all tires are the same size

Did you also replace the spark plug wires? The burn lines on the ceramic would indicate that it's jumping fire. Are the burn lines on ALL the plugs or just one or two? If you look closely at the wires in the dark, you will be able to see the spark jumping to ground if the wires are bad. If you have already replaced the wires and still have that issue, it's possible that you have a bad coil pack or ignition module.

Remove a couple bolts holding it on

The springs are bad. Shocks will not correct worn out springs.

Sounds like an emission problem. Take it to your local parts store (AutoZone. Advance, Oreilly's). They usually connect the scan tool and check for free.

try applying some WD-40 or light penetrating oil to see if it improves but it the rollers move then there is a chance that something has broken

possible problem can be the door check .It is located between the two door hinges. I have repaired a few doors by replacing the door check. I would closely inspect it .

check for bulbs out, has a flasher/module test before replacing
