I installed a new bulb but that was not it. I consulted my shop manual but it did not seem to address this problem. The low beam on the passenger side headlight is also not working. Could they be related? Any advice would be much appreciated. Thanks.

I doubt very much that the headlight problem is in any way related to the brake light problem. | | | | | Joined: Feb 2012 Posts: 206 Shop Shark | | Shop Shark Joined: Feb 2012 Posts: 206 | Thank you both.

Some grounding problems cause very strange symptoms and at times they don't appear logical. | | | | | Joined: Feb 2012 Posts: 206 Shop Shark | | Shop Shark Joined: Feb 2012 Posts: 206 | You are so right.
