If you are just talking about the windshield washer pump/motor that squirts water on the front windshield, there is no separate fuse for that pump. If you are talking about the front windshield wipers themselves then the fuse for that (including the washer pump) is located is the fuse panel inside the vehicle down below and to the left of the steering wheel. Below is a diagram of the fuse layout (first picture) and I marked the 10 amp fuse for the system. As I said if you are talking about the pump/squirter motor there is no separate fuse. Inside the wiper motor itself (located basically on the firewall on the drivers side) is an internal microprocessor as well as an internal relay for that pump. If the processor or the relay is bad, both are internal and the whole wiper motor assy. has to be replaced. It's one complete unit. There is a chance that the pump motor itself could be bad. In the second picture is a breakdown of the washer fluid reservoir. In order to get access at it which is where the washer pump motors are located the right front wheel and splash guard have to be removed. I have marked the 2 washer pump motors which are mounted on the reservoir. I cannot tell you which motor is which but the one for the front has 2 wires at the connector (a black & white wire and a black wire) The rear pump motor has a violet & light green wire and a black wire at its connector. That's how you can tell which one is which. You can test the motor by either pulling it out and applying direct power and ground to it to see if it engauges or while someone is engauging the washer inside the vehicle while you are down there, see if you are geting power at the black and white wire. Check that wire while it is disconnected and using a good separate ground. If you are getting power make sure the black wire is geting a good ground. If all is good (ground & power) than more than likely the pump motor is bad. If you have a power supply problem at the black & white wire than you are looking at most likely a bad wiper motor assy but check for an open power wire from the wiper motor to the pump motor. It's not quite as simple as it used to be. The wiper motor on your vehicle has like a mini computer in it. I'm gonna say the washer pump motor is bad which is the most common. Hope I was able to help and that I didn't get too technical on you but things are not like the old days with separate motors (wiper and washer).

First thing to do is retreive the trouble codes from the computer and then we can go from there.

Take your negative cable off your battery and leave it off for about ten minutes this will reset your computer and if your check engine light comes back on then you may have a problem

Both mirrors not working at once is an indication of fuses in my mind.Check the fuses and then adjust by hand to suit your viewing angles...The 'gears' are actually a screw type dealy and they dont 'strip out' easily.If its not a fuse... like I said... adjust them manually and be done with it... so long as the other functions of the mirrors are doing what they aught to...

You may have a wheel bearing that is going , causing the check traction controle light to display .
Or even a tire that is low on air pressure.... or brakes that need servicing...
Anything tire speed related will do ...

Make sure the sensors on the bumpers are clean.

Try changing the fuel filter.

PO 300 is multiple misfires detected
PO 301, 304, 305, 306 are misfires in cylinders 1,4,5,&6
PO 053 is HO2S Bank 1 Sensor 1 Heater Resistance
PO 106 is MAP/BARO CKT Range / Perf
PO 316 is Misfire detected 1st 1000 Revs.

On a misfire, I usually push towards the spark plugs, plug wires, and coil packs / distributor coil.
You have PO 106 and PO 053 that need to be inquired about at nearest AutoZone.
They can give you an idea as to what is the problem on these.

Did a MAP sensor **** out and cause all the misfires ?
Did a misfire cause the MAP sensor error?
You see what I'm saying ?...Something caused all the misfires...thinking MAP...but not that familiar with the function of the MAP.

Hope this helps...

alarm /immobilisor light on ?? try the spare key
