Service & Repair Manual

I have a knocking problem that comes from underneath the rear of the car, a 2002 Chevrolet Cavalier. Every time I accelerate, little or great, the knocking noise keeps coming, Any ideas what this could be? Thanks

Answer: If you cannot physically inspect your undercarriage by yourself, you must get your undercarriage inspected, you may have a motor mount failure or a suspension component worn out, inspect them before driving further in case there is a safety issue present.

How can I replace the rear wiper blade assembly on my 2007 Toyota Prius, (not only the rubber insert) How to detach the blade assembly from the wiper arm? Does anyone have a suggestion?

Answer: As far as I know,  the size of the rear wiper blade  on the 2007 Toyota Prius is unique, it is very specific. My suggestion is go to the parts department in your local Toyota dealership to find the right insert that fits the blade assembly, so you don’t have to detach the blade assembly. Good luck.

My 1963 Volkswagen Beetle is leaking fluid, does anybody know where the radiator is? I can’t find the location of my VW Beetle radiator.

Answer: This old Volkswagen Beetle is air cooled, except you have swapped the engine with a water-cooled engine, there’s no radiator. The leaking fluid at the engine should be oil or brake fluid.

My car, 2000 BMW 323i 4 door sedan has been experienced a weird problem, every time I unlock the door with the remote, the drivers side mirror starts moving upward by itself without turning the key into ignition position. Any ideas what this could be?

* added later: I have changed my original 2000 driver position door with the 2003 models.

Answer: The mirror in 2000 models is controlled by the door module, but in 2003 models, the mirror has a built-in module in the mirror motor itself. So the mirror is confused as can be. The most logical way to correct the problem is to re-program/code the General/Basic Module and retrofit the newer side mirror module with a GT1 with V44 or an SSS machine (BMW computers). This is what happens when unorthodox repairs are done without any knowledge of the consequences.
