1999 6.5L Suburban with 271k miles.
Several times this summer and all the way up until now I've noticed that when I go outside to the garage, I can faintly hear the blower running in my Suburban. I've never noticed it before this summer. It's not constant but it does run for a while and air actually comes out of the vents, both front and rear. It doesn't matter what position the blower switches are on or what vent settings are set when the vehicle is shut down.
I didn't care about it until now because it wasn't draining the batteries. When I got up this morning, I noted that the fan was running. I wasn't driving the Suburban and let it be (like normal all summer long). When my wife went out to fire it up this evening to head to the store, the batteries didn't have enough juice to crank it fast enough to get it to fire. Batteries are old enough that they should be replaced, yes, but I drove the vehicle a lot yesterday and they haven't shown any signs of getting weak lately. I really think the blower drained the batteries enough to get them too low to crank. When I hooked up jumper cables to my Blazer and let it sit a few minutes running charging up the Suburban, the Suburban fired right up like normal.
All grounds have been cleaned up and made sure they're good when I did the injectors this summer. I'm leaning towards a bad relay that controls the blowers as being the culprit, but I figured I'd solicit some input before I started replacing my relays.
