06 silverado dead battery issue

Have you ever replaced the battery?

I had one that stumped me and my customer for awhile .

When the customer left the vehicle he was hitting the power seat button down and it was sticking there.

After we found out that was what it was we removed the breaker for the power seats and never had a issue after.

Get your battery load tested to make sure its ok , I have seen more than once where a replacment battery was no good.

Also it needs to be a good draw to kill it in 4 hours.

I had the same problem on 05 silverado. It turned out to be defective bypass module gm-sl2. Once it a while, it caused the bcm to stay on, when remote start had shut down. Obviously gm-sl2 had some designed flaws & since had discontinued. I replaced it with an INT-SL and problems had disappearred.

Find out what bypass module in your truck. Hope this info helps.

I see you are in new york. Batteries have a lower reserve when its colder. I recomend aslo having your alternator tested.

Are your drive times short where you go? Sometimes with a weak alternator and short drive times coupled with colder weather battery problems arrise.

You should have a make and model availabel of what kind of remote start is installed not matter how ordered.

Not a lot of short drives for me.  Mostly I drive 1/2 hour to work.  Now that you mention it, though, the last time it happened it was only 5 minutes to my girlfriend's house.  It seems like a long shot, though, to be the alternator, since I made that trip to my girlfriend's plenty of times during the summer and no problem.  I realize that the colder weather is harder on a battery, but we've hardly seen "cold" weather for NY yet.  It's only been in the 30's at coldest at night and this happened during the daytime while it was 50 something. 

It's a Direkt Start I believe, not sure the model, but it's a 2-way remote start/alarm.  I've had them before from the same place and had no issues whatsoever, in fact, my mother and sister have different models from the same manufacture on their vehicles and haven't had a single problem.

It originally had an idatalink interface and just the other day we switched it to a DEI interface in the hopes that it would give us better luck.  It's only been a few days so far, but no problems yet (fingers crossed).

no idea... something in the mirror i think.... but i had to disconnect the starter and bypass to "prove" to them that it wasnt the starter causing the problem....strange thing was this problem supposedly occured right after having the starter installed... at first i thought it might have been the bypass module, but the module i used didnt do heated mirrors or seats, just locks and passlock.....

whatever it was was something they covered under warranty.....

i would disconnect the starter and bypass and try this for a few days.... i had a customer with exactly the same issues on a 05 back in 06 that we installed a starter on... we disconnected everything and the problem was still there.... turned out one of his heated mirrors was staying on and draining the battery.... nothing to do with my install but 2 different dealers told him "it must be the starter".......

Yes, this is a curious problem.  Please post a follow-up.  Inquiring minds want to know.

Thanks for checking in.  Here's basically what's happened since my last post:

- Tried an experiment by not using the remote start for a while.  It went well for a week or so then, BLAMMO, dead battery again.  It happened about 2 days in a row.

- I did some investigating because I was getting desparate.  I have a hi4 kit installed on my truck (just a relay that keeps the low beams on when the highs come on) and it wasn't working properly as of late.  I found that one of the connections had become a little corroded, so I replaced it and it worked fine.  Went a few days without problems, then went dead again....

- For some reason, my fog lamp switch sticks a little.  Though I've gotten very good at pushing it in so that it doesn't stick, I was thinking that for some odd reason maybe it was drawing on the battery sometimes, so I replaced it.  It hasn't gone dead since then, but it seems less likely to be the cause compared to...

- I put a load tester on my battery and checked it out.  It would sit at 12V, but when I applied a load, it would immediately drop to 10V and then slowly keep dropping.  I compared this to a known good battery, which only dropped to 11V and stayed there.  I also kept the load tester hooked up and used the remote starter.  When the starter engaged, the voltage dropped to 8V or less!!  I contacted the place I got my battery from and had it replaced under warranty.  It hasn't gone dead since (it's been about 2 weeks) and I've been using the starter right along.

Now here's the weird thing.  As I mentioned earlier in the post, I replaced the battery after this had already happened a couple times, so either my old battery was bad AND the new one was bad, or maybe there WAS actually some kind of problem with the remote starter and it's been fixed, but the battery was bad also.  I don't know and probably never will.  In fact, I'm not 100% sure that it is truly fixed since it's only been a couple weeks.  We'll see.

Another weird thing I noticed was that, when I put the replacement new battery in a couple weeks ago and began driving it, the voltage was not as high as it should have been.  It was only about 13V, but then I parked it for about 10 minutes and drove it again and it was then over 14V and slowly dropped down to 13V.  I got home, put it on a slow charger for several hours, and haven't noticed that problem again since (and believe me, I've been looking).  Not sure what to think about that.  I was worried my alternator had s*&t the bed, but it hasn't happened again.

wow, sounds like my journey!

If i'm not mistaking, the radio has a preset time that it stays on.  Of course it will shut off when a door is opened, but if a door is not opened, (you remote start it and decide to kill the remote start and never enter  the vehicle) it shuts off after about ten or fifteen minutes.  Others can verify that...

Well, it wasn't the alternator.  It's happened twice since then, about 2 weeks or so apart.  I did notice that for some reason my interior door light on the pass. side stays on sometimes until you open and close any door again.  I pulled the bulb just in case.

Well, I've decided on selling my truck, so I'm having the remote starter pulled in a couple days.  If I have the problem with my next vehicle when the starter is installed, we'll know what it was for sure. 

Thanks for all the help and suggestions.

Obviously this has been a while, but let me update here.  I removed the remote starter from my truck, but also found a bulb in the door that would sometimes stay on, so I pulled the bulb.  I wasn't quite sure which it might've been, but I sold the truck to a friend's daughter and she hasn't had a single problem....

Until this week.  Apparently last week she had a remote starter installed on it and now it's going dead every few days AGAIN.

I guess it was the starter afterall.  Apparently my/her truck just isn't meant to have one.
