Why would the cruise control stop working in a 1998 Chevrolet Blazer?

In my continuing series of questions about this truck, I present another:

I recently replaced my door panels on both the driver and passenger front doors since the old ones were broken. I had been driving without the driver side for some time.

Today, I go to drive down the freeway and noticed that my cruise control is not working. I don't know if this is somehow related to the door panel, I can't see any reason why.

The only thing I did notice was the little spring loaded stick, or plunger, whatever you would call it, on the left side of the dash is now quite loose. It still has spring tension, but instead of moving in and out in a straight path, it can now wobble in a 360 circle when pushed.

I assume this is the "sensor" that detects the door is shut, but does this have anything to do with the cruise control? If my door is not completely shut, according to this possibly broken sensor, is the cruise not going to work?
 
no, but on another note.. you might want to go and have your fuel pump replaced cuz that's gonna go out pretty soon too and it's better to have it taken care of now than having it strand you out in the middle of nowhere waiting for a tow truck. also have them look at the serpentine belt tensioner. those trucks are just crap, sorry if I offend you but it's the god's honest truth.
 
Change the fuel pump? yea thats why your cruise control don't work..lmao oh and your tires are low thats why..? yeaa ooook i have a 88 s-10 blazer, I've owned s series since I were a kid, and they have been really good trucks. I believe the thing your talking about , if its on the side of the dash is the switch that turns the dome lights on when u open the door, next time u open the door push that button and see if the light goes off, that has nothing to do with the cruise, nor does taking the panels off, you may have a vacuum leak since the cruise is operated by vacuum. Most common problem that I have seen is either split or disconnected vacuum hose, or mis-adjusted brake switch (at the pedal) or clutch switch (if manual tranny). Sometimes it is simply that the brake or clutch pedal is not fully returning - try lifting up on the pedal with your foot while driving and see if you can engage the cruise. In addition to the vacuum switch, check for operation of the brake light switch. I seem to remember that the vacuum switch will disengage the cruise simply by releasing the vacuum from the unit, but the brake light switch must activate in order to release the control unit signal. If you are just tapping the brake lightly to disengage the cruise (as I often do), but not activating the brake light switch, then it may simply re-engage as soon as vacuum is applied again. Hope this helps you out. Oh and joe the next time you spell GOD, you capitalize it , this is America!!!
