Hello all. Having an issue with my 07 ml350. The doors apparently keep locking. When I drive they will lock and then unlock and keep unlocking. When its off. I hear the locks continue to lock. All the locks are doing it and cant figure out the issue. Anyone have an idea?

Please UPDATE YOUR PROFILE in USER CP to include the year, model and where you live.

Maj. Dundee

Does this locking & unlocking occur after the speed of 9 MPH?

richrom2

It will lock automatically when I begin to drive. After a few minutes it will then all unlock and continue unlocking. For instance, right now it's off and in my driveway and I can hear the locks clicking.

Maj. Dundee

Why did you ignore the updating of your profile? It was a simple request.

richrom2

My apologies didn't even notice that

richrom2

How do I go about updating it

Maj. Dundee

Good Lord I provided you with the instructions. What more do you want?

richrom2

I got it. On phone and have to put it on desktop mode to see CP user

Maj. Dundee

OK, with the key out of the ignition, remove fuse #14 in the right side instrument panel fuse box and see if the locks stop actuating. Pull off the rubber door seal first then pry open the fuse door.

richrom2

I pulled the fuse and it stopped. Also, why would the lock and unlock switch inside not work?

Maj. Dundee

A quick guess would be because of the problem you are having.

What happens when you reinsert the fuse?

I believe you have a problem with the EIS,Electronic Ignition Switch, where you insert the key.

Is your CEL on?

richrom2

When reinserted the fuse it started back up again. What is the cel?

richrom2

Check engine light is not on.

Maj. Dundee

Did you recently buy this truck and what was the date?

Reinsert fuse #14. Turn key to the on position. Does your CEL illuminate and then goes out?

Remove key and with all doors closed, open tailgate and go to fuse box and remove fuse #40. Check to see that it is not blown. Close tailgate. Did the unlock and locking stop? If not, reinsert fuse 40 and close tailgate.

Then perform the same procedure with fuses 26 and 34.

richrom2

I removed #40 fuse. The gate did not operate but I all of a sudden was able to use the lock and unlock buttons inside. I checked the other 2 fuses and they were fine. I put the 40 fuse back and ran some errands and the locking didnt occur. After about 2 hours while driving, the locks unlocked.

Maj. Dundee

It's very annoying that I ask you a question and you do not answer it. Turn key to the on position. Does your CEL illuminate and then goes out?

richrom2

Some of my messages must not be going through. Good ol' Sprint service. Yes, when the vehicle is on the check engine engine lights goes out.

richrom2

Another thing also, when I go to unlock the truck to go in it. I will unlock and then it will automatically lock again real fast.

Maj. Dundee

Without having the codes read with a scanner, my guess would be you need a new tailgate lock.

I strongly suggest that you buy a scanner code reader and check for codes in the entire truck.

richrom2

I do have one. Would it still read codes even with the cel off?

Maj. Dundee

Again you are not being informative. Which one do you have?

Only certain problems will illuminate the CEL.

richrom2

My apologies. All you stated was that I should get a scanner. You never gave any specifics on which one I should get or have so I just assumed that any type of scanner reader would have been fine. I'll check on which one I have.

richrom2
