If sometime works fine and sometime not I would suspect a bad/loose wire connection. This is not likely but is a possibility, It may seem odd but car voltage can effect the electronic in a car. I would say while the car is running check the voltage at the battery. It should be showing over 13.7V because with the car running it will be reading the voltage put out by the alternator. Depending on the vehicle I have seen them put out 13.7 to over 15 volts.

I recently tried the DIY service and repair manuals from a website and it actually helped me repair transmission problem in my jcb 3cx site-master. It would'nt move forward or reverse, engine was good both solenoids for forward and reverse worked, but still couldn't diagnose the problem. I don't have much technical knowledge but I just followed it step-wise, and now it works perfect! covers diagrams, torque specs, PCV, everything got it from www.reliable-store.com

Having a qualified repair shop do diagnostic's on the vehicle would be your best bet . Could be any number of thing's ,engine mangement system sensor's , fuel system , ignition system , engine mechanical systems etc.... Could be as simple as just needing spark plug's & wire's , fuel filter . But , some testing should be done by a qualified technician with a professional scanner .You don't want to get into a guessing game , one person tell's you it's this or that , because without doing testing they are just guessing . 011 Fuel System Tests Fuel System Scan Data 012 Ignition System Tests Start Here these videos are just to show the complexity of these computer systems .

You have a worn out wheel bearing. Nothing else has this symptom.

No way to tell for sure without further tests. If the vent valve is faulty, replacement may fix the problem (valve and labor to do this will be the cost - estimate approx. $200). However, a number of other problems can cause this DTC so it is best to get a realistic estimate from a dealer.

There is a small plastic part on the pull down motor that comes in contact with the trunk lid latch. It is most likely broken off.

With the door key (same one for the trunk and glove box)

There is a big short in the wires that are connected to the steering wheel. Uncovering the wires requires the steering wheel to be removed. The air bag needs to be deactivated first. Special pullers are necessary to take the wheel off. Next is to remove all the screws that hold the plastic covers in place. This will expose most of the wiring. finding a pinched or bare wire should be easy to see.

I found this, w/amplifier. Don't know about part number? Found this info in my database. If not factory set-up, doubt if this wiring will help. If you can't read it, maybe you can hit control plus to enlarge. 26217368-wepcphjelpkx1uj0n0xvz3k3-5-0.jpg 26217368-wepcphjelpkx1uj0n0xvz3k3-5-2.jpg
