Oakland, CA

I have been in the automotive field since 1975 and have accumulated over 25 years of experience with General Motors products achieving the designation as a GM Master Technician. I am also currently certified and an ASE Master Technician, and hold an Advanced California Smog Check License. I have been the lead technician and team leader at a multi-line dealership. After leaving the dealership I spent a couple of years working in an independent shop and now find myself applying my experience for your benefit at RepairPal. My training includes numerous GM classes and college courses which resulted in an AA degree in Automotive Technology.

Question Answered: 

The PCV valve on the V6 engine in your 2007 Chevrolet Silverado should be located in the left (drivers) side valve cover - a hose will be attached which runs to the intake manifold. Do you know the fault code that is triggering the check engine light to come on? If you can tell me the code I can be of more help.

If the PCM on you 2005 Chrysler Sebring is telling you is lost communication with the TCM (transmission control module) I would be suspect of a faulty TCM or the communication link between the TCM and the PCM.

It is doubtful that the coolant sensor in your 1997 Cadillac Seville is causing your problem. I would suggest a complete cooling system inspection in order to find out what the cause is. I would not expect the high speed cooling fan to turn on until at least 226-230 degrees.

It sounds like the speedometer on your 1990 Mercedes 420SEL is reading in kilometers per hour instead of miles per hour. If there a switch located some where on the dash to convert the reading from metric back to english units?

Question Answered: 

The information you are referring to for your 2006 Chevrolet Trailblazer is service bulletin not recall information. The manufactures do not notify owners of technical service bulletins, only recalls. I would suspect the problem with your fuel gauge is related to the fuel level sensor located in the fuel tank. Many manufactures are having problems with corrosion on these sensors causing erratic fuel gauge readings. In the past I would have recommend to replace the fuel level sensor. However, there is something new to report. Chevron has included an anti-corrosive agent in their techron "plus" fuel additive. This is not available in the Chevron fuel with the techron additive, at this time it's only in the bottles of fuel additive. I would recommend to add a bottle (make sure it says techron plus) to your next tankful and give it a try. It may take a week or two for the cleaner to do its job but I have been hearing positive results. Please let us know how this works out for you so that we can pass the word along.

If only "some" of the instrument panel light are out on your 1998 Ford Escort then chances are some bulbs are burned out. Unfortunately, on most late model cars the bulbs cannot be replaced without sending the gauges "cluster" to a specialized repair shop. You can check with your local Ford parts department to see if replacement bulb are available - if they are not the cluster will need to be sent out for repair. You can use the following link to find your local dealer - http://repairpal.com/directory?address=75061&car_brand_names=Ford.

Question Answered: 

Very carefully! In some cases it may be necessary to remove the alternator on your 1992 Dodge Grand Caravan to access the rear spark plugs. Sometimes working from the bottom is also helpful, it just depends on the specific vehicle. What is boils down to is that you must remove whatever is in the way in order to access the back spark plugs, there is now "easy" way.

Question Answered: 

The "general" module often referees to the module that controls "body" type functions - your 2002 most likely follows this form. The body functions usually under the control of the general module would be the power door lock, lighting system, security system, power windows, power seats, etc. The general module may or may not be directly connected to the interior fuse box.
