The hose connection at the steering box can be real fun. The best bet is to cut the line off close to this fitting. Then use a 6 point socket to remove the fitting. The other end is not a prob!

Your switch is overheating or your breaker is overloaded. Are fog lights factory? if not they are probably on the same circuit. If that is the case you probably need to step the breaker up about 5 amps.

Trouble Code 13 indicates that the exhaust stream oxygen content sensor (O2 sensor) is not responding as expected. When cold, the sensor is 'biased' by the ECM to about 450 millivolts. Before it warms to at least 600 deg F (315 deg C) it acts as an open circuit and when the ECM reads it, it reads the 450 mV bias. The ECM expects the sensor to warm in a short period of time and begin sending its own voltages.
The link above is for code 74-77.

Have a diagnostician check that your fuel pump is operating correctly. Older fuel pumps tend to temporarily "fail" when they warm up, due to pump wear.

I lost power to the mirrors broken wire, under the dash..
So I removed the switch panel on the door, and installed a jumper wire from the door lock circut, to power the mirrors. The green wire is the power supply wire for the remote mirror switch. My mirrors are back working and all is fine.

Have the trans serviced. Once parts start dropping out it never ends well.

There are many things that can cause front end vibrations, I will give you a list and hopefully the information provided will allow you to narrow it down. Usaully front end shake is caused by a tire that either has a shifted belt in the tire or the tire weights could have falled off and the tire and wheel must be rebalanced, another reason for shake is if the shake occurs when applying the brakes it is a warped rotor and the brakes must be replace in the front end along with new rotor installed, the last thing that it could be is a loose or worn out front end part perhaps a tierod end. If i was you I would try rotating the tires from the front to the back and see if the shaking goes away if it does it is most likely a bad tire (shifted belt) or the tire needs to be rebalanced at a auto garage. after checking that first then jack up the front and grab the wheel and move it back and forth up the down to check for play or loosness, as I said if the shaking occurs while applying the brakes replace the brakes and rotors.

Try the autozone.com website and register the vehicle information. They should have an online repair manual that will be of some help to you. It doesn't cost anything and is a pretty handy resource. Hope this helped and best wishes.
