Looked under left side of dash, just to the right of steering column. No luck. Turn on hazards, and can hear it about midway under dash, but can't see anything. Don't wan't to disassemble car to find it. PLEASE HELP!!!

SOURCE: turn signals and hazard flashers quit working

There are two possible locations for the relay.

First in the fuse panel, close to the bottom.

Second, in some models they put the darn thing behind the dash in the center of the car, it's a real pain to get to if it's that one.

Good luck

SOURCE: 99 blazer steering column key is stuck in acc and will not move

o.k... you broke the key off in the cylinder... right... o.k... can you turn the key? it you can... usually you just put the key in the acc position... and just pulls out... now... some ignitions use a pin to keep the cylinder in... just hope you don't have one... because you'll have to pull off the steering wheel and the turn signal switch... just to get to it... them you'll have to get a small screw driver and remove the pin... not easy... any way... just use a big flat head screw driver... and ever so gently... pry out... when you get a new one... reverse the procedure to install... hope this helps man

here are the instruction the first set are the instruction on how to remove the turn signal switch as you will need them to remove the ignition

Removal & Installataion of turn signal switch

1. Disconnect the negative battery cable.
   
2. Remove the steering wheel.
   
3. Loosen the anti-theft cover retaining screws on 1976 models and lift the cover from the steering column. It is not necessary to completely remove these screws.
   
4. Depress the lockplate and pry the round wire snapring from the steering shaft groove. A lockplate compressor tool is available for compressing the lockplate.
   
5. Remove the lockplate, directional signal canceling cam, upper bearing preload spring, and thrust washer from the steering shaft.
   
6. Move the directional signal actuating lever to the right turn position and remove the lever.
   
7. Depress the hazard warning light switch and remove the button by turning it counterclockwise.
   
8. Remove the directional signal wiring harness connector block from its mounting bracket on the right side of the lower column.
   
9. On vehicles equipped with an automatic transmission, use a stiff wire, such as a paper clip, to depress the lock tab which retains the shift quadrant light wire in the connector block.
   
10. Remove the directional signal switch retaining screws and pull the switch and wiring harness from the steering column.
    
11. Guide the wiring harness of the new switch into position and carefully align the switch assembly. make sure that the actuating lever pivot is correctly aligned and seated in the upper housing pivot boss prior to installing the retaining screws.
    
12. Install the directional signal lever and actuate the directional signal switch to assure correct operation.
    
13. Place the thrust washer, spring, and directional signal canceling cam on the upper end of the steering shaft.
    
14. Align the lockplate splines with the steering shaft splines and place the lockplate in position with the directional signal canceling cam shaft protruding through the dogleg opening in the lockplate.
    
15. Install the snapring.
    
16. Install the anti-theft cover.
    
17. Install the steering wheel and connect the negative battery cable.
    
18. Check the operation of the turn signal switch.
    

1. Disconnect the battery ground cable.
   
2. Remove the turn signal switch as described earlier in this section. You don't have to remove the switch completely, just set it aside.
   
3. Insert the key. Position the key as follows.
   
   • 1976-83: With manual transmission, put it in the ON position; with automatic, put it in OFF/LOCK.
     
   • 1984-86: Two detent positions, clockwise, beyond OFF/LOCK.
     

1. Working through the slot next to the turn signal switch mounting boss, use a thin screwdriver to release the lock cylinder.
   
2. To install, insert the key in the new lock cylinder. Hold the sleeve and turn the key clockwise until it stops. Align the cylinder retaining tab with the housing slot and insert the cylinder. Push the cylinder in, rotate to engage, then push in until the retaining tab engages the housing groove.
   
3. Complete the procedure in the reverse of removal.
   

SOURCE: I cant find the center fuse block on my 03 yukon.

if you look under the dash (steering wheel) against the fire wall a little to the left is a black box with a plastic nut that sticks out. you can loosen it with your fingers and then just pull off the cover. The inside of the cover has a diagram of the fuses.

SOURCE: How do I disassemble the dash and steering column

Here is what I learned without a manual. (You may find that you have to use the tilt mechanism to move the steering wheel up and down in the process to gain access to fasteners)
1. Remove plastic pins on underside of the upper dashboard. About 7 of these that can be pried out with a large flat screwdriver. Careful to catch them all and keep both pieces.
2. Remove the lower dashboard trim panel and set aside.
3. Using a small Torx head driver remove all the torx fasteners along the upper instrument panel.
4. Remove the side panel cover on the driver's side (the cover that the fusebox cover pops into). This side cover is held in place at 3 slots, and needs slid down slightly as you remove it.
5. Unscrew the phillips head screw that you see connecting to the instrument panel face.
6. Go to the passenger side and repeat steps 4 and 5.
DO NOT TRY TO REMOVE THE MAIN DASH PANEL YET
7. On the drivers side, gently pull the main dash panel out a little ways and disconnect the plug to the light switch.
As I remember the main dash fascia panel is ready to be removed now. The A/C vents will come out with it. Make sure all the fasteners are removed from the top. Gently pry out the bottom, and then slide it down and remove it. Hint: Place the steering wheel in the fully tilted down position. Hint 2: You can lift up on the upper dashboard pad to assist in clearing all the top mounting tabs.
7. Using a 10 mm socket or torx, depending on your car, remove the bolts that hold the lower dash panel on the driver's side(These bolts are above your shins when seated in the driver's seat.)
8. Using a 10 mm socket remove the bolts that hold the top two corners of the lower dash panel (One on each side).
9. Unplug the traction control switch.
Disconnect the flexible tubing on the right side (just pull it off the connector) and disconnect the wiring plug that is down a few inches parallel to the flexible tubing. An option here is to pop the whole vent/grille out and leave the tubing and wiring intact.
10. Now you can remove the steering column surround. You need a torx socket, very small to do this...Sorry don't know the size but it was the smalles one in my kit. All fasteners are installed from the underside.
11. Start with the one you can't easily see. It is in the dark recesses by the tilt column lever.
12. Remove the other torx fasteners by accessing them through the holes. If you're socket is too thick or short you will not be able to remove the one in the middle, closes to the dashboard. Your choice, buy a new socket or just break the plastic off around that one.
13. You now have access to the lock cylinder and ignition switch. You will need an even smaller torx head to remove the ignition switch. The lock sylinder is removed by pressing in on the spring loaded release about 2 inches from the keyhole, on the side closest to the dashboard. The key should be in the run position during assembly and disassembly.
14. You can remove the steering wheel for easier access, but you do not have to do so to work on some of the components in the column.

Hope I didn't miss too many steps.
