I searched a lot, from different sources, for a solution that could help me. I think I read all the recommendations from google. I asked all my relatives, friends, and acquaintances for advice. I found three bulletins on the LR HVAC system. There is a little known process for calibrating actuators by airflow. I also decided to contact a good air conditioning repairman. The handyman solved my problem in a split second. I am delighted with the result.

WHAT WAS THE ISSUE?

we are having an issue with the headlights staying on

when we turn the key we have headlights then when we push the start button truck starts that's when we lose just the headlights

I have a 2010 GU 713 and the truck has been shutting off while I am driving and the ABS light comes on.  This happened about 2 months ago a few times so we took to the dealer  They said EGR valve was clogged., so we changed the EGR valve and truck has been running ok  Today it shut off twice again.  Has anyone have these issues
