Need help with 2 issues. Blend door actuator and parasitic battery drain

[AN292]

1. Blend door issue fixed


2. Battery is dying every day and I cant find out why. I have connected the battery to my multimeter and its 14 volts car on. Turning the car off it will either drain to 12.7v and stay there, or drain to around 10v and will need to be jumped. To check parasitic draw I've removed the negative cable, and connected my multimeter negative lead to the cable and ground lead to the battery peg. Im getting a reading of zero for Milliamps and amps.


Thanks in advance.

Does the dome light turn off correctly? Do you have an aftermarket alarm? Does this happen if you leave it unlocked overnight?

I make sure all sights are off every time. It does have a viper alarm, I bought the car about a month ago and it came with it.

I have never left my car unlocked overnight either, apartment parking lot.

Do you think the alarm is the issue?

We see on here time and time again that aftermarket alarms cause the draw over time. Not saying for sure yours is but............

If you’re getting zero milliamps when you connect your meter in series, why do you think you have a parasitic draw as opposed to, say, a bad battery?

 

[OR VietVet]

Yea, surprising that if the meter is set up and hooked up correctly, there should be a small amount of draw showing for keep alive memory in some of the systems. Like the clock......

I would have the battery tested before any conclusions.

Bridge your DMM over the fuse contacts for whatever is powering the Viper alarm when the car is in full off (key out, door open, waiting for things to shut down). Obviously need to remove the fuse to do so.

To confirm your multimeter is setup/reading properly, turn on a small current draw such as the radio or dome light.

FYI- A co-worker had an avalanche that was draining the battery every couple of days. It turned out to be the re-circulation fan was stuck on

So I ended up buying a new battery just to cross that off the list of possibilities and I'm having no more issues. Thanks for the help everyone

I kind of suspected that, that’s why I said to have it tested. Glad it was a simple fix.

There are many steps in checking for parasitic drain. You can just hook up a multimeter and hope for the best. There are many systems that need to go into a sleep mode. Usually takes about 15 minutes for the entire car to go into sleep. If you have a system that’s not going to sleep, it will cause a drain deepening how big the draw is. Best way is to use a amp meter around the negative cable.
Pop the hood, lock the latch, open the drivers door and lock the latch. Arm the alarm and wait. when all the systems go to sleep and you do register a draw, you can start pulling fuses one by one to see what makes the draw stop.

My 07 Tahoe had a back lift get open message that made it lock and unlock automatically all the time. Used to kill my battery a lot. I found pulling the fuse for the horn kept it from sounding and helped keep it from dying. Might start with the horn fuse if you don’t mind driving without it. My dads suburban has a Paris iris drain in the automatic seats. So that could also be it.
