Weird noise and vibration in the dash when I turn
Your heating system is broke in the dash. The doors or gates that change where the air is to go, has a broken hindge or actuator. Your heat is set to defalt to the defrosters as a safety thing. The vibration, I would say, is your fan & it may have been the thing that started your whole problem. The fan has something wrong W/ it, weather it has dropped, the shaft that it runs on is bad, or it is just going to the bad. To fix, the whole dash has to be dropped so that the gates or doors can be accessed for repairs & the fan, it's half in & half out of the passenger compartment. I've had 3 or 4 dashes out to do this work but it is TIME CONSUMING. Wish you the best, GOD BLESS.....

I have a 2003 trailblazer and the engine fan stays engaged. The temp runs at 210
Jeff, this is a very common problem with our platform. Replace your fan clutch, while you're there, replace your waterpump also, it's cheap and it WILL go out. If you can swing it, buy a Hayden brand fan clutch, or buy one for an 08 or 09', those are better. If you do it yourself, do yourself a favor. Cut a notch in the upper fan shroud where the upper radiator hose is. Will save you tons of time, potential breakage, and frustration.

2003 trailblazer v8 4wd crank but no start. Fuse4 under hood panel has no power. It should be hot in run and start key position. Where does it get power i cant find power side prints
It like this the battery supply's the power to the starting motor to crank the engine over that is a good point to start checking .
However the ignition switch opens the circuit like a light switch on your wall open closed.
Now you need to figure out what works when the key switch is in run position do you have major power windows seats door locks if so the battery is fine .If not you need to take a good look at the battery TEST IT if that's good then look at the fuse box any fuse that would stop power flow would a 20 to 30 amps yellow or green the # will be on the back of it
Next you need look at main connections and grounds like from the battery to the starter and solenoid yank on the cable to the starter from the battery check your main ground cables fusible links look for corrosion.
Then you can start thinking about what you need to take APART.

Opened my sunroof heard a crunch now will not close all the way
You are all incorrect with diagnosis. And there is no button hokd calibration, stop it. Read on. So easy a caveman could do it. 1.5 hr job only removing glass.
(Inside vehicle)Remove the 4 hex screws that attach the glass to the rail guides and remove the glass panel. This will also allow for manual movement of rails. The glass is adjustable(hight only) so mind the position when removing the screws.
. Hold the glass like a pizza pan for it will slide down as u loosen each screw, remove the screws then lift upward and rest glass on roof. Removing the glass will give a good view of both guide rail and concting arms. The crunch you heard was one of the connecting arms plastic rail guide tips breaking. Picture a catamaran for a moment. The pontoons are the plastic pieces that slide fore and aft inside the rail and keep everything aligned. It will be the outside(pontoon) guide piece that failed. When that broke, a lot of play was allowed and began binding. Bless the poor folks who bought a whole new unit for nothing. I fabricated two pieces from the plugs off an older dell power supply. The plugs were the exact same length as the factory guides and even beveled ends. I only had to cut the plugs in half long ways and then install on the slider. Even the holes that are already in the plugs fit the stud (pivot stud that the pontoon slides onto) the guide. Sunroof will not vent if any of the pontoons are damaged. When venting, theses guides(pontoons) pivot upward through a slot on the top side of rail slot and rest on the rail so not to close by wind. Hope this helps.
