So first of all my cruise control works, some times. At times it will take off from my foot and other times I have to help push the pedal into position and even then the speed drops. I noticed my wipers wont do anything unless I click both indicators first and then the wipers will go. So is my indicator/wiper/cruise stick going out and I just need to replace it?

Sounds like it'* going out. The switches get dirty over time and wear out.

good thing autozone provides replacements for cheap

Ok, um I dont know how to get the actual lever unconnected. Also my grandpas 97 sierra will not start if there has been a cold rain or i think in the cold in general, I took it and got it read once and they told me that o2, missfires, map sensor I am thinking its the map sensor, am I right?

Teh MAP sensor helps the PCM decide how much fuel is needed. If that'* off it can run rich, and that will over load the O2 sensor. Start by changing the MAP. The misfire is likely from running rich in this case.

if you change the turn signal you will have to remove the steering wheel and air bag

And I'm guessing thats not an easy thing to do is it?

need a big socket I'm not one hundred percent what size. also a steering wheel puller you do not want to strike the steering shaft. Also the death that can occur from the air bag. But the air bag is easy to remove as long as the proper steps are taken.
