Reset check engine light
First of all, you should'nt do this unless you know what the problem is.. or what tripped it. I had this problem when my husband and I were replacing a head unit and disconnected the old head unit, a/c and other stuff then turn the car on. This made the light flash. The first time we took it in and got charged $50 to reset it. The second time we did this procedure and it worked.
ECU Resetting Procedures
Timing is extremely critical. If it is NOT DONE within the specify time, the ECU will not reset and the Check Engine Light (CEL) will continue to remain ON.
A stop watch or an analog clock with a second’s needle will be useful.
Reset Check Engine Light Procedures
1. Confirm that accelerator pedal is fully released, turn ignition switch “ON” and wait 3 seconds.
2. Repeat the following steps (2a and 2b) procedures quickly five times within 5 seconds.
2a. Fully depress the accelerator pedal (HARD).
2b. Fully release the accelerator pedal.
3. Wait 7 seconds, fully depress the accelerator pedal and keep it for approx. 10 seconds until the CEL starts blinking.
4. Fully release the accelerator pedal (while the CEL is still blinking)
5. Wait about 10 seconds.
6. Fully depress the accelerator pedal and keep it for more than 10 seconds.
7. Fully release the accelerator pedal (The CEL light will continue to blink).
8. Turn ignition switch to “OFF” position and now you can start the car. The CEL light should be gone.
If the CEL light continues to remain ON, repeat the above steps. Timing is EXTREMELY critical to resetting the ECU.

My windshield wipers won't shut off
Little comes to mind other than it could be a fault with the motor self-parking switch or the wiper sweep/delay relay. There is an outside chance it is the switch.
I suggest you start by locating the relay and give it a hefty tap with a screwdriver handle in case the contacts have stuck. Pulling out the relay should at least stop the wipers but unfortunately the only practical test method is to try it in another car or substitute it for a known good replacement.

How do i replace a nissan murano stepper motor?
The stepper motor is not replaceable on this auto. The ECM and crank sensor controll the idle process for this Nissan. First change your crank position sensor you know the cars computer is ok. This is where i would start. Once this has been accomplished if this did not fix your problem.please return and ask me for me and i will go threw the Idle Air Relearning Process with you. I REPEAT DO NOT DO A RELEARN PROCESS WITH THIS FAULTY CRANK SENSOR ENGINE CAN RACE OUT OF CONTROL DAMAGING YOUR ENGINE AND FRYING YOUR ECM WITH OVER VOLTAGE> Your crank sensor is picking up the wrong signals telling the engine it is rotating at a completely different RPM is what is wrong and that is the reason for the radical RPM and transmission shifts. THe trans is programmed to shift at certain RPMs but it cant change right because the crank sensor it telling it it is at 1100 rpm and its really at 2200 rpm. it is simple computer network failure. Change this and get back to me if you have any other questions

07 Murano will sometimes not
Have the battery tested. During outside temperature changes, it can effect batteries and even kill them prematurely. They will cause the system to act like it has all kinds of electrical issues. If the battery checks good, the next call I would make is to the Nissan dealer and ask about TSBs. Let me know about the battery and if you need any further help with this.
