Do Blazers have auto locks when driving? Like in most new cars when you go over like 15mph it locks the doors? Mine doesn't and was wondering if thats how they are or if somethings wrong. I tried searching for this but couldn't really find anything. Thanks.

 

mine automatically locks when i put it into gear. I dont know if it is a special feature though.

 

This feature is modifiable via Tech2 (dealer). You can either have lock out of park or rolling lock. Both features unlock in park. In my Rainier (GMT360 platform), this is all modifiable with the steering wheel controls.

 

The doors never lock on mine though not rolling or shifting out of park. So that would mean something is wrong with them right?

 

Or they've been programmed not to lock... Or someone cut a wire somewhere... I know on my old Lumina, it would lock when you put it into gear, but would never unlock... So I cut one wire on the chime module, and the door stopped locking...

 

Oh ok well then are there fuses to check for this? I just wanted to see if it was something that should be there that isn't but now it's a maybe with what you say so I have no idea haha.

 

well I have a 2000 LT...and my doors do not automaticaly lock...aren't supposed to...I don't know if that helps you out at all

 

I guess I needed to clarify my original post here... For any '98+ this feature can be activated if you so choose. You have three options, inactive, lock out of park, and rolling lock (locks at ~15mph).

 

Oh ok thanks, would I be able to change that with a scan tool? We have one at school I could use because I wouldn't want to bring it to a dealer for something like this.

 

I'm not sure. I know it is an option with a Tech2, but not sure what some of the other scan tools are capable of.
