Recent purchase and install of TS/HS Lever
When I needed a new lever I thought of 1aauto. The price was right and I reviewed the installation video for what appeared to be a challenging task. However, after viewing the video, and getting the lever I completed the removal of the broken lever and installed the new one in less than 30 minutes. It was easy and pretty much the same as in the 1aauto video. The lever works as described.

When replacing turnsignal,light switch does this have anything to do with airbags?
Lee S February 24, 2019
No this does not have anything to do with airbags but as a precaution always discount your battery before working around the steering column.

Has no effect on airbag ,its just removal of column casing not wheel
