    My car vibrates at my feet whenever I accelerate at 45-50 mph. Only when I accelerate though... what is wrong ??
    I just bought a 2001 Buick lesabre. The car rides fine until I accelerate to 45-50 mph. It is almost like the whole front of the car shakes... not just the steering wheel but my legs too. This only happens when i keep my foot on the petal. If i take my foot off then ...

    Blower will not shut off even when car is shut off. What would cause this?
    I have a 2004 Buick Rainier. I went to shut off the car and the blower on the passenger side under the dash continues to run unless I take out the fuse.

      Blower resistor is shorted internally. Replace blower resistor and you problem will be gone.

      I think that is a two piece hubcap. With a hubcap and center cap. The center cap attaches to the hubcap. and the hubcap has plastic nuts that attach it to the wheel lugnuts. You have to pry out the center piece first. If you pry on the outside edge you will break it.
      Not sure of your exact hubcap style, but typically you remove the center of the hubcap with a screwdriver or tire iron. You have to pry out the center circle. there is usually a small slot to fit your prying tool. Once the center cap is off you will likely see black plastic lugnut covers. The plastic nuts just unscrew with your tire iron. The plastic nuts hold on the hubcap. Once they are loose the cap will come off to access the lugnuts.

    My low beams will randomly stop working but the high beams work fine.
    Fuses, bulbs, relays all have been checked. I replaced the right headlight section because it was cracked. that worked for a while but didnt entirely fix the problem

      suspension components with excessive play, did they balance wheels correctly, or excessive CV joint play in axles.

    Were is the blend door actuator located
    I took out the center console.i found what looks like a blend door actuator but it controlls the back air vents it works and changed the course of air as i changed it with the back controlls.i have cold passenger side and hot on driver side.front controlls change ...

      HOT AIR DRIVER, COLD AIR PASSENGER SIDE.‏

      The system is low on refrigerant, and only after it is confirmed if it is in need of refrigerant or not can the blend door actuator be a cause. This is a confusing symptom - cold on pass side and hot on the other, it even throws off good mechanics, but in the majority of cases the cause simply is that the system is low, The refrigerant only fills half of the evaporator and the half that it fills is directly inline with the pass side ducting and the other side that lacks refrigerant is inline with the driver side ducting.

      Note: Cool on the driver side and hot on the pass side is almost always caused by a faulty pass side blend door actuator. If it were the reverse (cool on pass side and hot on driver side the cause is always that the system is low on refrigerant.)

      How much refrigerant did you add? Every vehicle has a specific amount to add, weighted in lbs or grams. Too much or too little will allow ac system to function improperly. At idle, it is normal for the compressor to engage and disengage. It will not run full time all the time. This is because of the high side pressure switch. When the pressure reaches a specific level (say around 250 psi), the compressor clutch disengages the compressor. Then once the pressure drops to a point, say around 100-150 psi, the clutch re-engages the compressor, and so on.

      The blend door may be stuck in a position that blows air through the evaporator and heater core. Outside air is cooled through the evaporator, then gets re-heated when it passes through the heater core. Check climate controls and blend door motor for funtionality.

      Your orific tube may need replacement. This is what separates the high and low pressure sides of the air conditioning system.

      You may have moisture in your system. If your system has a leak, even a small one, refrigerant will leak out. Most people will simply add more refrigerant into the system. This is the improper way to go about it. If the system was ever open to outside air, moisture will be trapped in the system. The low pressure side of the system can reach degrees below freezing. When you have water in the system, the water freezes and turns to ice, usually inside the orific tube or evaporator core , and blocks refrigerant from circulating. This scenario is most noticed when the air conditioning system works for about 5-10 minutes, then all of a sudden the air isn't cold anymore.

      You may have excessive internal blockage in the air conditioning condenser. Back flush the system

      You may have excessive external blockage at the condensor. Bugs, leaves, and debris can get caked up over time in the front of the condensor fins, restricting enough air from flowing through too cool hot refrigerant. Also check to ensure the fins aren't bent.

      If you are sure compressor is engaging but you are not getting any cool air than more than likely you have a temp actuator malfunction. Check air conditioning line temps, low side should be cold and high side should be hot. If low side is cold you know its making it inside HVAC case but temp blend door is not opening by actuator. If this is the case please let me know and I will give you a solution.

      Headlight switch directs current to the headlights and running lights to turn them on or off, check it and replace it as necessary.

    The first 2 months of owning this vehicle I was getting 365 miles on a full tank but now I can barely get 300 miles.
    This car has 82600 miles. I wanna try replacing the fuel filter but I don't want to waste the effort and it done help.

      Have to start somewhere. If the fuel filter has not been replaced in [years] it is a good place to start. Check the air filter and see if dirty enough to block air flow. Plug in a code reader and see if any fault codes are stored. There is no way to diagnose this without some money spent. Replacing a fuel filter that has 40K miles on it would not be considered a wasted effort to try to solve a driveability problem.

      I agree plug in a code reader and go from there, there lots of things that could cause your gas mileage to drop.
