Hi everybody, and welcome to my “stevenofpa” YouTube Channel!
This video shows you what it’s like to see this broken vacuum hose line connector that is dry rot damaged deteriorate disintegrate due to heat and high temperature in the van engine compartment vehicle car truck suv cuv crossover minivan passenger work vehicle. You can see the van it’s a Chev Chevy Chevrolet Express 1500 2500 3500 vans are all similar, have dashboard mounted hvac ac A/C air conditioning heating, in this case the temperature blend door mode door defroster vent floor defrost windshield was not working, only the air was blowing on the windshield, the temperature was only on hot, because the vacuum source was lost, due to the bad hose, this is called failure mode analysis fma it’s something mechanic mechanics technician technicians do when diagnose diagnosing a problem with an automotive type system analysis. Pretty cool!
to fix the problem just have to replace the rubber hose and it worked again. yes!
