Probably a bad ballast. You can swap the left and right ballasts and if the problem follows the ballast you've found your problem.OK, thank you all for your answers. Now I have another problem.
After spending $225 for 2 new headlights and a little knuckle busting and a lot of swearing to install, my passenger side high beam still does not work (original reason for replacement)
Anyone have any idea why this could be happening?
I have a 2011 CXL AWD
You can just turn the wheel all the way to the left or the right, depending on which side you're doing. It takes 15 minutes tops to remove the screws for the wheel well and pull it back enough to get easy access to the bulb....but the replacement procedure requires you to remove the front end of the car! There is a back door through the wheel well but you still have to remove the tire and the inner fender skirt.
Enclaves are the kind of car you should not own past 100k miles unless you have your own mechanics shop.
Do you know what bulbs Pep Boys used? I tried to call and service has already closed. Dealer wanted $300 per bulb + labor and told me I needed both bulbs so I'm looking elsewhere.....
