Yes , the steering needs to be pull .
Disable the SIR system. Refer to SIR Disabling and Enabling in SIR. Remove the steering wheel. Refer to Steering Wheel Replacement . Remove the upper and lower trim covers. Refer to Steering Column Trim Covers Replacement .
Important: The abrasion sleeve located on the steering column wire harness assembly must be reinstalled. Make note of what connector is coming out of the abrasion sleeve for installation purposes.
Remove the wire harness assembly (1) from the wire harness strap (2). Disconnect the turn signal and multifunction switch assembly connector from the SIR system coil connector.
There could be a video on youtube show how to do it .
You need to check the wires in the steering column. Take the column cover off, probably phillips-head screws, so you can see the wires. Somewhere the tilting function is putting pressure on the wires to the dimmer switch. It may be pulling loose a connection, just a fraction, to lose contact. You may also need a new dimmer switch. Or a multifunction switch if the dimmer switch is attached that way. The headlight switch is on the dash, isn't it? If it is, the headlight switch is not the problem, it is the wires in the steering column or the dimmer switch. If the dimmer switch fails, you will have no high or low beams, no head lights at all.
You must remove the steering wheel this means you must disarm the steering wheel airbag. To do this disconnect the battery negative cable while working on the car. Remove the **** shell plastic covers on the steering column the screws for them are on the underside they should be cross points, now remove the steering wheel nut and apply the puller you must purchase to the bolts holes and turn the jack screw in until the wheel pops free. After the steering wheel is off remove the clock spring ribbon contact drum under the steering wheel and then the switch just slides up and off once the clamp is released that holds it to the steering tube...
Hi Shannon, befor you dive in and replace the indicator switch I would suggest you check the flasher unit. To replace the indicator switch you will need to remove the steering wheel (this usually means using a puller) Don't forget to punch match marks on the steering wheel and the column which must be aligned when assembling. Remove the steering wheel center cover. then the covers on the steering column Removed the screws (usually four) holding the stalk switch. don't forget to disconnect the battery and the wiring connection to the stalk switch. After replacing the assembly is opposite.to dismantling. Regards John
Hello, try to start by checking the headlight relay and headlight fuse. You
also may want to check to make sure the bulbs aren't blown out. If those
parts check out to be fine and in working order, you may need to
replace the turn signal assembly in the steering column. This part
controls the hi/low beams. This may sound crazy but, when GM wired
their older trucks, they wired the headlights to go from the battery,
to the hi/low beam switch, then to the headlight switch (to the left of
the steering wheel) then out to the light bulbs. You can kind of test
to see if this part is good by making a fist and (with your headlights
on) gently hitting the plastic cover for your steering column that is
right behind your actual steering wheel. This could cause your
headlights to flicker on and off.
***As per Haynes Manual for your Vehicle*** Warning: if your vehicle is equipped with a suplemental inflatable restraint (SIR) system, always disengage airbags before working in the vicinity of the sterring wheel to avoid accidental deployment of airbags.
1. disconnect the negative cable at the battery
2. Remove the steering wheel if it interferes with the access to the steering column covers on your vehicle. Remove the steering column covers.
3. Unplug the wires from the ignition switch, remove bolts and lift the switch off the steering column.
4. Installation os the reverse of removal.
Hope this Helps! I have a an illustration and it looks that the switch is on the left side of the steering column. If you need any information or help removing the Steering wheel or steering column covers let me know! Good Luck.
Should be fairly easy. Make sure to disconnect the positive battery cable. Remove the cover from around the column behind the steering wheel. Should take a star driver to remove the screws holding the cover together. Once the screws are removed pop the cover apart and you will see the multifunction switch on the column, should have two to three screws holding it to the column remove the screws and it should come out pretty easy replace with new one and put back together.
The ignition crank shaft is broken inside the Steering Column Lock Assy. You will need to buy a new assy (cost appr. $202.21) and 2 steering lock bolts (cost appr. $4.96 ea) at a Toyota or Lexus dealer. Call either dealer for best price and availability. To replace you'll need to remove the black snap-on panel below speedometer then remove the screws securing the driver side dash. Behind the dash is a steel plate. Remove that and remove the steering column covers by turning the steering wheel to access the screws. You'll see that the SCLA is secured by 2 break-away bolt (this is an anti-theft feature). Use a dremel tool with cutting disc to make a notch in the screw head to remove with a flathead screwdriver. If this doesn't work your other option is to cut the bolts where the assy bolts together. Remove the broken SCLA and remove the key FOB and install into new SCLA. If your mechanically incline this should take about 2-3 hrs. and save you $300-400 in labor cost.
Part numbers are same at Toyota and Lexus dealers.
