    When my truck sits idle at a red light it starts to shake like it wants to shut off.
    I have 70,000 miles. I added gas a week ago. I just noticed the problem today after work coming home when i got off the freeway and stopped at a red light. No engine light came on. About 2 weeks ago I had my oil changed and my tires rotated. Today was the first day ...

      The engine service light will come on very soon, maybe by tomorrow and then you will attach a code reader and see what codes have set. Until the light comes on or fault codes set you cannot know what to do. The light WILL come on. Either there is a misfire or a bad vacuum leak most likely.

      When you rotate your tires did you also done a wheel alignment?
      And if your tires and wheels are aligned, and have the same tire pressure try to check (and clean if needed) the condition of your air filter and fresh air intake hose, throttle body and MAF sensor (and its electrical connector).

    Sometimes my headlights don't come on when I turn on switch, just parking lights
    This usually happens after I have been driving the car for awhile. I shut it off to go into a store and when I come out and start car and turn on lights they don't work. A few times they would come on if I put on my turn signal.

      Check the fuses if loose and fit them properly. Check the alternator output; perhaps this happens when there is a lot of accessory loads open and the alternator output is low that why the lights went dim or out. Check also the alternator belt if worn or cracked.

    Water is leaking from my truck after the water pump has been replaced. It doesn't run hot unless I turn the heater on.
    the guy that fixed it said that it needs the waterpump housing to stop it from pouring out the antifreeze. But I've never heard of a waterpump housing.

    Why does my heater/AC only work when turned on at the highest level?
    Whenever we use the AC or Heater we have to turn the fan up to the highest level of 4 before it blows air out. I am curious if there might be an easy fix for me to do or if it is best for me take it in. The van has about 100,000 miles on it and I don't know ...
      Danamelia its your blower motor resistor gone bad autozone has them for your car one is front unitmotor resistor....part number........JA1540............$64.99 and a Auxiliary heater motor resistor..........part number..JA1528.......$33.99.....hope this helps you and good luck.

      I have a 1996 Villager and it is made to be that way. The climate control in the vehicle is computer controlled and the A/C or heat blower fan only comes on high when manually placed into the upward highest position. The vehicle has it's own built in thermostat that takes a few minutes to get an accurate interior temperature of the vehicle before it does anything.

      Try this; press the "Automatic" button on the Climate Control Panel and adjust the temperature you desire with the Temperature button just below it and wait a couple minutes until it the vehicle's computer can get an accurate interior temperature reading, -chances are if the current temperature of interior is significantly lower or higher than what you select depending on outside temperature it will automatically adjust the blower fan to an appropriate speed.

      If you want to manually adjust the blower fan to blow out heat or A/C faster just use the thumb wheel on the right side of the Climate Control panel up or down. It will only blow out faster if you manually select the faster speed.

      There is nothing wrong with it, that's the way it's supposed to work. Give it more of a chance, when the cars computer registers the interior temperature it will automatically adjust the blower fan according to what temperature you select and the interior temperature of the vehicle.

      Let us know what happens.

      Probably fine. Remove the spark plugs and inject an ounce of oil into each of the cylinders and then distribute the oil with compressed air into each cylinder for a few seconds. then let it sit overnight. Next day try to turn the crankshaft manually. if it moves OK, charge or replace the battery and start it up or at least see if it starts. the gasoline that is in there is likely degraded but I have started at least two cars with no issues where the gasoline was 5 years old and it ran decent. You just never know, you have to just try to start it and see if everything is there.

      It is possible that moisture is present in your ac system and it develops into ice when reaching the expansion valve restricting the flow of Freon in your system that’s why you feel hot and when it melts it allows the Freon to circulate and you can now feel that your ac is functioning. Take your vehicle to a certified ac technician to perform evacuation in your ac system and perform a leak test. You can use the Find a Shop feature of AutoMD to find a list of shops near you with their address, telephone # and labor rate per hour.

      All the required steps and pictures would be in the appropriate repair manual. This job you are doing is a huge heater core job that would frighten most experienced mechanics.

      well you need to test it could be the light sensor which is usually mounted to dash and looks like a little dome near the base of the windshield. Or it could be the headlight switch. Do the lights work when you turn them on manually?

      Replace the oil pressure sending unit located at the rear of the driver side of the engine next to the cylinder head, just above where the transmission and engine meet and are attached. It is standard procedure to replace the sensor with what you said is happening. Don't set your hopes too high.
