Emergency Flasher Button Will Not Work

[maxwell1]

I have the obs pickup, 2000 model

 

The emergency flasher button will not work,

 

You push it down and it's suspose to pop up and the flashers start working.

 

you can push the button down but it will not pop up to the on position.

 

Think a little wd-40 would help it or other material? May have dirt and stuff in switch as they mounted switch on top of steering column and I do not spend a lot of time cleaning the old work truck, if you know what I mean.

 

If lube would not work, has anyone ever changed this switch?

 

Thanks for your assistance as I need the flashers from time to time in my work. Must get it fixed.

Did you check the fuse????

2000 Chevrolet Chevy C Silverado - 2WD | Sierra, Silverado, Suburban, Tahoe, Yukon (VIN C/K) Service Manual | Document ID: 513366 Inflatable Restraint Steering Wheel Module Replacement

Removal Procedure

Caution: This vehicle is equipped with a Supplemental Inflatable Restraint (SIR) System. Failure to follow the correct procedure could cause the following conditions:

• Air bag deployment

 

• Personal injury

 

• Unnecessary SIR system repairs

 

In order to avoid the above conditions, observe the following guidelines:

• Refer to SIR Component Views in order to determine if you are performing service on or near the SIR components or the SIR wiring.

 

• If you are performing service on or near the SIR components or the SIR wiring, disable the SIR system. Refer to Disabling the SIR System.

 

 

 

1. Disable the SIR system. Refer to Disabling the SIR System .
   
2. Turn ON the ignition.
   
    
   
3. Turn the steering wheel 90 degrees so the side of the SIR module is at the 12 o'clock position in order to gain access to the holes behind the steering wheel.
   
    
   
4. Insert a screwdriver into the access hole and push the leaf spring to release the notched pin that retains the inflator module.
   
    
   
5. Turn the steering wheel 180 degrees in order to gain access to the remaining hole.
   
6. Insert a flat-bladed tool into the remaining access hole and push the leaf spring to release the notched pin that retains the inflator module.
   
    
   
7. Tilt the top of the inflator module rearward to gain access to the SIR wiring.
   
8. Disconnect the SIR lead wire from the clip on the inflator module.
   
9. Disconnect the SIR lead wire from the clip on the steering wheel.
   
    
   
10. Disconnect the connector position assurance (CPA) retainer from the SIR connector.
    
11. Disconnect the SIR connector.Caution: When carrying a live inflator module, make sure the bag opening is pointed away from you. This minimizes the chance of injury in the case of an accidental deployment. Never carry the inflator module by the wires. Never carry the inflator module by the connector on the underside of the module.
     
    Make sure that the bag and trim cover are facing up whenever you place a live inflator module on any surface. This is necessary to provide a free space for the bag to expand in the unlikely event of accidental deployment. Never rest the steering column assembly on the steering wheel with the inflator module face down, and the column vertical. This may result in personal injury.
    
12. Remove the inflator module.
    
13. Fully deploy the module before disposal. If the module was replaced under warranty, fully deploy and dispose of the module after the required retention period. Refer to Inflator Module Handling, Shipping, and Scrapping .
    

Installation Procedure

 

1. 
   
    
   Caution: When carrying a live inflator module, make sure the bag opening is pointed away from you. This minimizes the chance of injury in the case of an accidental deployment. Never carry the inflator module by the wires. Never carry the inflator module by the connector on the underside of the module.
    
   Make sure that the bag and trim cover are facing up whenever you place a live inflator module on any surface. This is necessary to provide a free space for the bag to expand in the unlikely event of accidental deployment. Never rest the steering column assembly on the steering wheel with the inflator module face down, and the column vertical. This may result in personal injury.
   
2. Connect the SIR connector.
   
3. Connect the CPA retainer to the SIR connector.
   
4. Install the SIR lead wire to the clip on the steering wheel.Important: Verify that the wiring is not exposed or trapped between the inflatable restraint steering wheel module and the steering wheel.
    
   
5. Install the SIR lead wire to the clip on the inflator module.
   
    
   
6. Press the inflator module into the steering wheel firmly enough that the module engages and latches the notched pins in the leaf springs.
   
7. Rotate the steering wheel back into the straight position.
   
8. Enable the SIR system. Refer to Enabling the SIR System .

Hope this helps, I would check the fuse first and see if that is busted, and then check the Flasher under the Knee Bolster panel, if those are in good working order, then you will have to disassemble the steering column (and airbag) to get to the switch.....a note, none of the hyperlinks will work, but I have posted all of the relevent information onto your thread regarding each repair (Fuse, Flasher, Hazard Switch Replacement)
