problem #1

May 042016

Sierra 1500 SLE 5.3L

  • Automatic transmission
  • 170,000 miles

A/C driver side starts blowing hot air

Since I have to shut it down and restart it is a pain in the caboose. i also notice the sound of door/panel open/close. need to pull control head out and check vacuum lines and fittings. It always seems to occur on deceleration or braking. Anyone else checked this idea out?
