This came from a 2008 Jeep Commander.  This Jeep ran and drove but engine was knocking junk.  This was checked out before we started stripping the Jeep.  No cracks or breaks in this, no knobs falling off.  This switched and worked like it was supposed too.  Check out the pics good and make sure this is exactly what you need before you buy it.  This is sold as is, all sales are final.  No returns.
