The instrument cluster illuminates the interior lamps when an unlock signal is received from the vehicle security module. The illuminated entry feature will be canceled when any of the following conditions are met:
  • 25 seconds have elapsed since the illuminated entry feature was activated and the interior lamp control is not activated (door ajar or courtesy lamp switch on).
  • The instrument cluster receives a request from the vehicle security module (remote transmitter lock button pressed) and the interior lamp control is not activated.
  • The ignition is in the RUN or START position and the interior lamp control is not activated.
The instrument cluster illuminates the courtesy lamps when any door is open or ajar. The courtesy lamps shuts off when the doors are closed and the illuminated entry feature is not active or when the vehicle speed is greater than 5 mph (8 km/h). The interior lamps are not reactivated until the vehicle speed is less than 3 mph (5 km/h) and a new door open warning lamp signal is received.
The instrument cluster controls the courtesy lamps illuminated entry function by activating the battery saver relay.
The panel dimmer switch is integrated into the headlamp switch and controls the interior lamps by activating the instrument cluster through circuit 1034 (BK/WH).
The vehicle security module sends a signal to the instrument cluster on the UBP network circuit to indicate a request to turn the illuminated entry feature on or off.
The on-demand lamps, glove compartment assembly, homelink module, puddle lamps and illuminated vanity mirrors are controlled by the battery saver relay. The battery saver relay becomes active (relay coil is energized) when the instrument is in the awake mode, or in the sleep mode (relay coil is de-energized).

First you want to remove the brake caliper assembly, rotor, and then the axle hub. Then you want to take a pry bar between the inner tulip and differential and vigorously tug on it until it pops out. Make sure you have a drain pan to catch any fluid that comes out of the differential, and refill as necessary. the CV shaft should come out and allow you to drop the shaft onto the ground.

When you reinstall the half shaft, give it a few good short jabs to get the snap retainer to pop back into place in the differential. Make sure the shaft is all the way in where the race is inside of the seal. Once you have confirmed the inner tulip has reseated in the differential, then reverse the above procedure.

I am sure you already know this, but PLEASE make sure that if you don't have a hoist to do this job, make sure that it's on a concrete surface with approved jack stands, PLEASE don't trust your life to a hydraulic or screw jack as these things can shift and cause the vehicle to fall on you. This risk is especially great doing this particular job as it requires a lot of tugging and hammering in the event the wheel hub is stuck to the spindle assembly. PLEASE remember, "Safety first". Also wear OSHA approved safety glasses as dirt and or rust can fall in your eyes.

It was clicking fast because it was only operating 2 out of 4 bulbs. You need to use a test light to find out where you are losing the power. It could be any place between the turn signal switch and the lights themselves, including the switch itself.

Blinking quickly is either a bad bulb or bad circuit/connection. If the bulb works OK when switched to the other side you will probably need to have a mechanic look at it.

It does so by design and to prevent dieseling.

jack the vehicle up and put on stands
remove the diff housing as a complete unit
depending on where the crack is it may be possible to have the housing welded up by an accredited engineering shop and if possible have the area properly reinforced to prevent it cracking again

The timing chain tensioners are located with the timing chain inside the timing cover and usually are not changed unless the timing chain assembly is replaced. Why would you change them?

I know it sounds a bit difficult but fuel leaking is serious danger so with this id siphon tank dry (don't use a drill pump ) and undo fasteners and hoses/wires that hold it too truck , lowering it to ground , a carefull inspection of approx. area of leak will tell the problem , your looking for cracks in plastic or rubber hoses , these might be very small and fine look closely
if cracks are in the tank , unless you know someone with a ultrasonic welder id replace the tank

If the tank is right full to the top it could be the filler hose or vent hose leaking at the connection with the tank and if it is not right full it probably has a hole in the side of the tank
