Question Answered: What would cause the speedometer to not accurately display MPH?
April 02, 2010, 03:19 PM
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: gas gauge does not work, starts going to empty
April 02, 2010, 03:12 PM
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.
Question Answered: INSTRUMENT PANEL LIGHTS
April 02, 2010, 02:49 PM
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: how to change plugs and wires on the back side of engine?
April 02, 2010, 02:45 PM
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: what is a general module
April 02, 2010, 02:38 PM
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.

Question Answered: drivers belt BUCKLE not Latching.
April 02, 2010, 02:17 PM
It is possible that some sort of debris has gotten the drivers seat belt buckle. Whatever the reason the buckle is no longer working I would suggest you have it replaced for safety sake. In most cases the buckle can be replaced without replacing the belt also. It's generally not a very costly repair.
Question Answered: Where is the ECT sensor located?
April 02, 2010, 02:13 PM
I am assuming you have a 4.6 liter northstar engine in your 1999 Cadillac Eldorado. If that is the case the coolant sensor should be located in the rear cylinder head under the coolant crossover manifold, not a very easy place to access.

Problem Reported: Speedometer Not Working and/or Code P0722 Stored in PCM
February 18, 2016, 02:18 PM

The speedometer may stop functioning with code P0722 stored in the powertrain control module (PCM). This may be caused by a worn speedometer gear due to coolant contamination of the transmission fluid. If contamination is found the radiator is most likely at fault. The transmission should also be thoroughly inspected and repaired or replaced as required.

Problem Reported: Fuel Gauge Needle Stuck on Wrong Side of "Empty Stop"
February 23, 2012, 10:17 AM

Do to a low or erratic voltage condition, the fuel gauge needle may "jump" around and become stuck on the back side of the "stop" below the "empty" indicator. This does not mean the gauge is broken. If the gauge cover is removed and the needle is gently moved back around to the correct side of the pin, the gauge will again function normally. When the needle is moved back to the correct position, the electrical problem that caused the needle to jump in the first place must be corrected or the needle may jump around again. The most common problems that cause this condition are a weak battery or corrosion on the battery cable ends.

Good car, too bad there are not more like these.
Comment: Floor Mats and Unintended Acceleration
July 10, 2012, 12:02 PM
A well placed strip of heavy duty, self adhesive Velcro on the back of the floor mat may help keep it in position. First check to see if the "loop" side of the Velcro will grab the carpet. If it will, placing a strip on the bottom of the floor mat at the edge near the drivers seat should help.

Comment: True or False: Let Your Car Warm Up Before Driving
April 14, 2011, 08:36 AM
Cpete, When idling or driving a vehicle when cold, condensation will form in the exhaust system. More exhaust flow through the exhaust system while driving a cold vehicle will actually warm the exhaust system faster that if you were to let the engine idle until the exhaust system warmed up.
