    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.

      Need more information - what happens when the right turn signal is activated? If the right signal does not work - then suspect the turn signal relay or turn signal switch.

      The parts are readily available from these many on-line sources,,,,, - to list only a few possibilities. For example, they (RockAuto) list the turn signal switch assembly (in the steering column) from around $105.00 for your vehicle.

    Why does heater blow cold and sometimes hot?
    My park Ave. has about 140,000 miles. I've changed the thermostat and put it in the correct way, changed serpentine belts, flushed and replaced the coolant. When it is at idle, cool air comes out the heat vents, when I rev. it to 1500 rpm heat comes out. When I ...

      Possible bad blend door actuator, sticking. Does your park ave have dual zone comfort settings? Temperature settings for the driver and pass side or is it just one setting?

      dual zone comfort settings.

      So with all details in that I needed to know, your cause is a partially clogged heater core. if you go to a garage they will sell you a new heater core at a huge cost. You can very likely unclog this one and it will be as good as new. use compressed air and blow air into the inlet or outlet tubes of the heater core. Do it several times and inbetween, put more water into the core. The water assists in unplugging and pushing on the junk that built up in the core probably in one spot when it gets hit with some air pressure. Just one thing though, don't let the tip of the blow gun seal off the pipe where you are blowing in the air because you don't want the core to have to feel 100+ psi. Wrap a rag around the tip and the inlet and that will allow sufficiuent blowby. Put a rag around the outlet so you don't get a bath when you pull the trigger. Do it a few times and then hook up the hoses again and try the heat. You will be amazed and you will feel like you dodged a bullet.

      Thanks a million. I will try that and let you know the hot results.

    Dash Lights Dim when starting;
    The car wouldn't start, just got click click click. Jump started it and ran it for awhile. The next time I started it, the dash lights were very dim for a bit, then got brighter. Help? This just started.
    • John's Auto Repair
      The dash lights dimming while cranking engine is not abnormal. However I would suggest you have
      your starting/ charging system tested. Most auto parts stores will do that for free.

      Check the positive crankcase ventilation ( pcv ) valve, it may be plugged up and restricted the blow by gases from the crankcase to recirculate.

      Check the fuel pressure regulator also. I have seen leaking regulators that will flood the engine with fuel when the diaphram leaks. You can easily check for this by removing the vacuum line from the regulator while the engine is running. When you remove it there should be no fuel present and the line should be dry. If you remove it and it is wet or spurting fuel then it is bad. This problem is common on 90s GM vehicles. It would also cause extended cranking when warm, hard starting and excessive fuel consumption. Usually would start fine in morning then you drive to store and shut it off when it is hot. When you come back to start, the engine cranks over for a long time and is hard to start. The regulator should be attached to the fuel injector rail and will have a small plastic vacuum line attached to it. It will be identified on the underhood vacuum diagram and emmisions sticker. Other causes would be leaking injectors, clogged PCV, plugged exhaust or engine misfire. Your vehicle may just need a tune-up.

      It may be a blown head gasket. Firestone (if that is your auto repair provider) should do what is called a cooling system combustion test to confirm a bad head gasket or rule it out. This can have other causes like a bad water pump impeller or a totally clogged radiator or even air in the system, but I will assume that Firestone had someone work on the car that knows that this cooling system has to be manually bled of air....?

      In Instrument panel fuse box confirm that you have battery voltage on both sides of the T/SIG / BU LP/ BTSI fuse 1B with key on.
      Confirm you have battery voltage on the PINK wire that goes to the turn signal flasher with key on.
      Confirm that the Purple wire at the turn signal flasher is a ground when the turn signal is turned on (left or right turn.)

      Add a new ground to the ground wire that goes to the headlights , you can find the wire with a power probe or a test light hooked to the positive battery cable

      You can purchase a cooling system pressure tester. Remove radiator cap, install tool, do not
      go over the recomended pressure labeled on the cap.

      About the flush is it mandatory that you take the thermostat out to do the back flush or can you do it a simplier way?
