It sounded like from the right side, but I was to concerned about what was happening. So thats really not a definite.
I bought a code scanner, but it fails on the first click, and gives lean codes on 2nd click. I would think the lean codes are from the car being on, but not running.
Edit: Messed with OBD-II Scanner, need to read codes while car is on or on first click. Second click will give lean both sensor because of being in accesory(ie car on, but not running).
Started the car. Whining/grinding/squeal is from the passenager side. It is not as loud as before but I can still here it. It is worse with the defroster on.
Could this have something to do with pulleys?
I'm lost I don't know whether I should run my car or not
