AnswerFor the First Generation Murano there are 2 AWD lights, one that says AWD and one that says AWD LOCK. if the AWD Light is on, Then you have a Problem in the AWD System, if the AWD LOCK light is on, then your AWD is stuck on on, or you just have to turn it off.
Im not sure if this is your problem but the fuse to switch from awd to fwd is ground not hot. So if the wire is skinned somewhere and grounding out it could cause that.
Camshaft Position Sensor / syncronizer
in order to clear the codes on your 200 safari first you need to fix the problem in the awd system and should clear by it self. The only thing that can turn that light is speed sensors wrong, speed sensors are not the only thing that will turn the service AWD light on. Wheel speed sensors are related to the ABS light
There are several reasons why an AWD light comes on in a Buick Rendezvous. A few reasons could be burned oil, gear oil is hot, or even a burned out clutch.
I would bring it in, because you can never be sure
That usually means your AWD is not working properly.
That would require a massive modification of the vehicle. It would be much cheaper to just sell this car and buy a AWD.
It would cause light to refract differently because the angle at which the light hits the glass block would alter and there for the way the light refracts would also alter.
I have a 2000 olds alero and the signal light only work sometimes, What would cause that?
