Question Answered: 

As I recall the PCV valve is quite difficult to replace on the V6 engine in your 1993 Pontiac Grand Am. If you are having no problems with your PCV system I would recommend not replacing the valve. Considering the age of your vehicle if you do decide to replace the valve it may be a good idea to have the rubber grommet and vacuum hose that attach to the valve as the old ones could be hard and brittle after all these years. The grommet goes into the base of the intake manifold and the short vacuum hose connects the valve to the vacuum side of the intake.

I would suspect you have a problem with the steering wheel air bag "clock spring". The clock spring is a coil of wire which will wind and unwind as you turn the steering wheel. The circuits for the steering wheel radio control also pass through this coil assembly. Broken wires in this coil assembly are not uncommon and if a wire is grounding intermittently that could cause the volume to change by itself. Confirming this fault with a volt/ohm meter is possible by may be a bit complicated.

You have a difficult situation. The interior door panel on the affected door of your 1995 Honda Passport will need to be partially or completely removed in order to release the lock assembly to get the door open.The problem here is that the door panels are designed to be removed with the door open. Care will need to be taken not to damage the door panel when trying to remove it with the door closed. Once you have access to the lock assembly you will then need to find the correct lever to move in order to release the lock. Once the door is open you can reset the child lock and also diagnose the fault with the outside door handle.

You could have an engine or transmission mount that is failing. This can be more pronounced in the lower gears due to the fact that you tend to be accelerating more in these gears than the higher gears. I would suggest a compete inspection of your engine and transmission mounts.

Do you have power seats in your 2002 GMC Savana van? If so an inspection of the wiring in and around the seats would be in order. Coming out of the floor under the seat should be two fairly large wires, one orange and one black. Pay close attention to the large orange wire, that would be the circuit powered by the 25 amp fuse that keeps blowing. Look for damage to the insulation of the orange wire in and around the seat. If the orange wire shorts to ground the 25 amp fuse will blow. If you don't find any thing in the area of the seats or you don't have power seats, try and follow the wire harness out of the fuse box and look for damage - look carefully around the area of the park break assembly. You should know when you finally find the problem, there should be no mistaking the damaged wire. If the copper strands of the wire are OK and not broken all that will be necessary to make the repair will be some electrical tape and possibly some tie straps to secure the wire away from whatever damaged it.

The P0410 code should not have anything to do with the coolant sensor. P0410 means the air pump system is not working. The are pump should run for a short time after cold engine start. You should be able to here the pump when it is running. If the pump does not run, check fuses and relays, make sure you have power and ground to the pump during the time it should be on. If you hear the pump run then check for proper air flow out of the pump and through the check valve(s).

I sounds like you have two different problems. First the brake light - make sure the brake master cylinder is full, if not top it off with the correct brake fluid. Low fluid in the master cylinder can cause the brake light to come on as the fluid in the cylinder moves around. If that does not fix the problem try wiggling the parking brake lever and see if the light will flicker, if so the problem could be with the park brake switch. The fuel gauge problem could be caused by a faulty fuel level sensor or the gauge itself could be stuck. If the fuel gauge moves when the wire to the fuel gauge is disconnected at the fuel tank that would indicate a problem is most likely in the fuel tank. You may need a qualified technician to diagnose your fuel gauge problem.

Question Answered: 

There are several items that rotate in conjunction with the serpentine belt. Any one of which can cause a noise when turning. Sometimes it can be quite difficult to pinpoint the cause of the noise. Some items which the serpentine belt can turn include: idler pulley(s), alternator, a/c compressor, power steering pump, and water pump. If a "pump bearing" has now been diagnosed as the cause of your noise I would suspect it is the power steering or water pump. I am sorry I cannot give you an estimate with out knowing which part has failed. However $350 does not sound to far out of range for either part. Before proceeding with this latest repair you may want to try and find out how sure you mechanic is that this latest repair will take care of you noise problem.

Question Answered: 

The fault with your security system is most likely due to a wiring problem in the steering column. There are two small wires the go to the ignition lock cylinder that allow the theft module to "read" the resistor in your ignition key. Right now the wire is probably partially broken and will make connection sometimes and sometimes not. The system should be properly diagnosed to confirm this problem. If indeed the problem is with the lock cylinder wiring the ignition lock cylinder will need to replace and a new ignition key made.

Question Answered: 

Rattling noises from the suspension area can be a bit difficult to diagnose. A complete inspection of the front suspension and struts will be necessary to correctly diagnose the noise. It may be possible to bounce the front suspension and hear the noise. If that is the case you can look around while a helper bounces the vehicle and see if you can pinpoint the noise. There is now way to provide a cost estimate with out knowing what the problem is.
