Q:Funny enough the van runs great, I had brought it from my 76 year old Dad in great condition, it only had 92thousand plus miles on it and it‘s a 1997. I‘ve had it for 2 weeks when the check engine light came on and the speedometer and odometer stopped working. What could be the problem?

Could possibly be the electronic control module. Take it to a dealer or shop. They should be able to hook it up to a computer that will help them diagnose what is wrong.

Q:This only happens when I drive for long periods of time.

ETS is an electronic traction control system that retards engine performance to help control wheel slippage. When there is an engine dtc or trouble code the pcm disables the ETS system. Take it to your gm dealer and have it diag. My just be an engine related concern.

Q:I have a 1999 Dodge Ram 1500 pick up with a v-6 engine. The previous owner had installed an alarm system but kind of half disconnected it; you still have to hit the alarm button before you can start it, which I like but there‘s no sound. The problem I am having is that the bing bing bing bing bing sound happens EVERY TIME I open the door. It should only happen when the key is in the ignition or when there‘s a light on, but it happens every time the door is opened. How do I fix this? Do you think it has something to do with the alarm system, maybe a wire got crossed somewhere?

Sounds like the alarm system is the problem. You'll need to get a detailed wiring diagram for the ignition system and one for the alarm, then start tracing wires. Only other way, is to take it to an auto electrical shop (not an installer) and have them go through it.that will be pricey. Doing it yourself is very time consuming.good luck!

Q:My car, a Mercedes 1996 C280 has a check engine light on. I‘ve looked at the common problems first like checking the oil, but everything seems fine. I want to find out what the problem out myself without having to spend the money. I heard that I can input a code and the number of times the dashboard flashes is the answer, but I have no idea how to do anything like that.

The trend is toward new trucks with wider trailer tires and drivers too those new designs run cooler and quieter. WE will still call 10 wheelers 18 wheelers won't we?

Q:I recently installed a new audio system in my truck, then i started to notice the battery light come on. it went off for a couple days, then i installed a capacitor just to be safe and then the battery light came on and has stayed on... any ideas on the issue. all the audio equipment is installed correctly. 300 watt amp and 1 farad cap.

How old is the battery ? if it's older then three years it's time to put a new battery in your truck nowadays battery's don't last long because of the newer electronics

Q:Just got a 2012 Nissan Frontier. It has lights on the rearview, green one on left always on, and the other one stays off. I don't have the Homelink system and can't find anywhere in the manual what else they might be for. Anyone know?

You may have the auto dimming rear view mirror. Nissan calls it (automatic anti-glare) Owners Hand Book section 3 page 15 Green light on means that when head lights from cars behind hits the sensor photooptic cell that causes the liquid crystals inside the mirror glass to darken. Good Luck

Q:Why is the car bulb easy to burn? Where is the problem

In general, the life of the brake light bulb is shorter because of the high frequency of use. If the continuous burning of the words to see if there is a bad place in the lampholder, poor contact will cause the current is too large, resulting in burning bulbs.

Q:I would like to ask you, 04 A6 xenon lamp, the height of the standard is what ah? Adjust the headlamps with tips or tricks? I sometimes feel low, and sometimes feel high, more depressed, I set the car against the wall, but they do not know what the standard is, how to tune it into high, ask you, for example, near light, What is the standard for me?

Do not use the wall when the light, the car to open the road to the road, the light point of the tune in the 30 meters distance and two points together, the far point can be transferred to the ground parallel to the wall is transferred two far Spot parallel.

Q:How to adjust the car headlights gap

It is estimated that the headlamps are not installed in place, either sheet metal or not done well

Q:My check engine light is on and i got it check at Auto Zone. It came up as an emission vapor problem. I replaced the gas cap.( reset the computer) It came back on. The motor is running fine and there have been no other problems. I search all the hoses for cracks and leaks and cannot find one. Any idea what I should do next before I take it to a garage?

Very likely a stuck evap vent valve, but only a diagnosis can verify that, unless you want to gamble on my educated guess alone. That is the most common evap system failure and the part is relatively inexpensive and simple to replace (it's at or near the evap canister).
