BugsyC Posted March 3, 2019 Report Share Posted March 3, 2019 Since I had electrical work done on my Eldo,the blower motor is always on low.The HVAC is off but you can hear that motor going.When I shut the car off,no more fan..Something got hooked up wrong I'm guessing..The turn signal switch is what was worked on..Where to look about this fan running issue?

sonjaab Posted March 4, 2019 Report Share Posted March 4, 2019 MOST GM cars with a/c the fan always runs! Its sorta a offshoot of the old GM Astro ventilation in the 70s GM vehicles. My 93 Caddy or my 84 Z-28s fans are always running even if the HVAC is in the off position. 93 DeVille-13 Chevy Impala 72 GTO - 77 Triumph Bonneville 84 Z-28 Syracuse NY Link to comment Share on other sites More sharing options...
BugsyC Posted March 4, 2019 Author Report Share Posted March 4, 2019 I hear you but,either I never noticed it before or it just started..It's a new sound.I thought when I pushed off,the system went off? Link to comment Share on other sites More sharing options...
rockfangd Posted March 5, 2019 Report Share Posted March 5, 2019 Should turn off. If blower motor went out though it would do what you describe. But would likely stay on after key is cycled off as well. Is your back seat one turned off?
