If it is the steering wheel shaking, it is most likely a front brake issue. You can often visually see through the wheels to see the pads, but there may not be much you can see. A shaking usuaully indicates an out of round or thickness variation condition with the rotors. Special measurement tools are necessary to check this, but many times pad and rotor replacement is feasible since it is often needed by this point anyways. If after replacing the pads and rotors you still have this issue, it is recommended to take it to a professional for further diagnosis. See the 2011 Dodge Journey Troubleshooting guide for more help

If the high beam and the low beam is out on one side, it is very possibly a blown fuse. On this car there is a separate fuse for each side. The fuses are located under the hood, in the large fuse box on the driver's side of the vehicle. The cover for the fuse box has a guide on the inside labeling the fuses. The headlight fuses are large, square shaped 40A fuses. The left side is labeled LIght 1. The top of the fuse is clear so that you can see the metal band to indicate if it is blown. If the fuse is blown, it may only be a symptom as well. Check the bulb(s), and any visible wiring near the headlight for torn or exposed wires. If all seems OK, replace the fuse, but be aware it may blow again immediately, indicating deeper issues that need to be checked by a professional. If the fuse is OK, then it is possible (although unlikely) that both bulbs are bad. You can swap the bulbs from the other side to check, being careful not to touch the glass with your fingers as oil on your fingers can cause a bulb to...

Since the brake lamp on only one side is not working, it should not be a fuse. You may want to check the socket that the bulb fits into - it includes some circuitry that can be burnt out as well. An easy way to check is to swap the socket with the side that works. If the light then works, you know it is the socket that is bad. If it still does not work, another possibility is that there is a computer system code - yes the lights are controlled by a computer in this car, and if there was a short detected (which can happen in rare cases when the bulb burns out in a particluar way), the computer will have disabled the power supply circuit. In this case, the memory needs to be cleared. A dealership can clear it with a manufacturer's scan tool, but that may be costly. An alternative may be to disconnect the battery for 30 minutes. This will clear other memory, including radio presets, but may solve your problem. If it does not, it may need professional diagnosis to identify other possilbe wiring issues. See the...
