Works great
Good price, equal to OEM, 1A Auto has a video explaining the whole process, and got rid of a random blinker (turn signal) noise that has haunted me for the past 10 years!

does part include dimmer option ?
Dorothy G on Apr 23, 2017
BEST ANSWER: The turn signal switch has the hi and low beem function built into it, by pulling it towards the drivers position it will change your headlights for low to hi beem.
It doesn't control the dimming of the instrument panel at all though..
Hope this answered your questions..

How long did it take to remove the bolt from the junction block?
Jonathan W on May 8, 2017
BEST ANSWER: about 15 min's I didn't see the bolt in the middle of the block at first, and it's hard to pull apart at first. hope this helps
My headlights won’t come on and the high beam indicator light is on the dashboard, could replacing the combination switch fix the problem?
Edgar M on Mar 22, 2018
BEST ANSWER: Check the connections underneath the engine-bay fusebox first. (Remove fusebox and turn it over) look for loose or corroded terminals. Poor crimping is not uncommon. After that it might be headlight switch or relay. I doubt the turn switch is the issue.
Does this model come with the Air Bag connection as shown in the picture?
Deborah on Feb 20, 2018
BEST ANSWER: I am assuming so it is a module that just plugs in. Not a difficult process but you need a special small screwdriver that I had to go buy.
