    Why do my brake lights and tail lights keep going out?
    Brake lights work when lights are off but when lights are on the driver brake light and tail light go out. Also blinkers act as if going out but are new.

      Make sure you have the right bulbs in. Many other bulbs will fit but not work right. Sometimes the tail light assembly goes bad or gets cracked. The assembly has a circuit board type setup, i had to replace mine before.

      Take it to a mechanic before something brakes and a wheel falls off. It could be a wheel hub going bad it is hard to say.

      I wouldn't drive that till you get it fixed. Are you 4wd? It could be a drive-shaft joint or wheel bearing. You might be able to safely raise and support the vehicle, while you shake and pull on the drive shaft joint, see if get any movement. Spin the tires, see if you recreate the noise? Maybe you can get a location, front/back, left or right side?

      There are safety issues with getting under a vehicle. Safety is your responsibility. I can't see anything from here. You can always take it to an alignment shop?

      The problem you are having lies within the switch/actuator that controls flow direction through the dashboard area. As a safety feature, the default position for the air to blow is at the windshield. This is to prevent windows from fogging up.....if the direction default was to your face, de fogging wouldnt do anything were you to request it. The climate control unit, climate control module, wiring, or actuator would be at fault if air flow direction does not alter.

    Airbag warning light is on, what fuses could I check?
    the light just went on, I think it could be a blown fuse, which specific fuses should I check?

      Its not a fuse. You need to use a code reader that can communicate with the air bag module and extract the fault code numbers in order to proceed with a diagnosis.

    Why do my head lights automatically turn on and off repeatedly while driving at night
    rround 250000kms I drive allong for bout 15 minutes at night with my headlights on then they will flicker completely on and off the only way o over ride it whilst it is happening is to hold the dipper switch back on high beam how do I fix this ?????

      Several possibilities; faulty wiring / connection at the headlight switch, faulty / loose / worn headlight switch, loose headlight relay. Try this as a first step, run a jumper wire around the headlight switch itself. See if the problem goes away. If yes, then the problem is the switch itself - and it must be replaced.
      The parts are readily available; try these on-line sources; www.partsgeek.com, www.rockauto.com, www.discountautoparts.com, www.autopartswarehouse.com, www.jcwhitney.com - to list only a few possibilities.
      In fact, they (RockAuto) list the replacement headlight switch from around $10.00 for your vehicle.

    My perform service light is coming on. What kind of service does it need?
    It initially said low coolant but that has been filled

      The perform service light illuminates when the previous mileage interval is meet or exceeded for certain preventive maintenance tasks, such as for an engine oil and filter change.

      This indicator is different than the check engine light. Once you have completed the recommended service, just toggle through all the options in the overhead console until you get to one stating "O miles to service" and press and HOLD the Reset button. That should reset it to 3,000 miles or whatever the mileage interval is set to.

      For the oil and filter change - check the 'How-To-Guides' feature on the AutoMD website for specific steps, details and tools needed.

    R-12 Sight Glass. Are a few white bb shaped particles supposed to be there? Is this flow indicator or dessicant?
    I had the AC recently repaired and flushed. It did have oily bbs in the sight glass and lack of R12. Compressor did have a leak and there might have been a dessicant break from the drier. I got home to check the sight glass again after service. A few white bbs are ...

      Yes, the a/c system sight glass should be clear; no bubbles of any size during the system operation - when it is working correctly. However, the lack of bubbles (unless the system has a refrigerant charge) may also indicate an empty system.
      The presence of bubbles in the sight glass is an indication of a system likely low on refrigeration charge or some other problem.

    Transmission Fluid Change
    Owners manual says to change at 60,000 miles. I only have 44,600 miles on Liberty but is 6.5 years old. Should I change anyway due to age or wait? Fluid level cannot be checked as their is no fluid dipstick in 2007 model. Must be done at dealer.

      Will not hurt anything to change the fluid and filter earlier than the recommended 60k miles interval.

      How to check the transmission fluid level;

      1. Verify that the vehicle is parked on a level surface.
      2. Remove the dipstick tube cap.
      WARNING: There is a risk of accident from vehicle starting off by itself when engine running. There is a risk of injury from contusions and burns if you insert your hands into the engine when it is started or when it is running. Secure vehicle to prevent it from moving off by itself. Wear properly fastened and close-fitting work clothes. Do not touch hot or rotating parts.
      3. Actuate the service brake. Start engine and let it run at idle speed in selector lever position "P".
      4. Shift through the transmission modes several times with the vehicle stationary and the engine idling
      5. Warm up the transmission, wait at least 2 minutes and check the oil level with the engine running. Push the Oil Dipstick 9336 into transmission fill tube until the dipstick tip contacts the oil pan and pull out again, read off oil level, repeat if necessary.
      NOTE: The dipstick will protrude from the fill tube when installed.

      6. Check transmission oil temperature using the appropriate scan tool
      7. The transmission Oil Dipstick 9336 has indicator marks every 10mm. Determine the height of the oil level on the dipstick and using the height, the transmission temperature, and the Transmission Fluid Graph, determine if the transmission oil level is correct.
      8. Add or remove oil as necessary and recheck the oil level.
      9. Once the oil level is correct, install the dipstick tube cap.

      There is a special dipstick you can buy thats used just to check fluid level. Chrysler uses a starscan and the special dipstick to check fluid level. The fluisd is supposed to reach a certain temperature before you take a reading. Here is one of the dipsticks you can buy, there are other companies; Chrysler uses Miller tools,:

      It cant hurt to have it changed early. Based on the low mileage with the age , I would assume you are doing mostly city driving which is stop and go which would be harder on the transmission that a car that did mostly highway miles. But it you car so its your choice.
