Remote door unlocking problem

[feenster]

Hi all,
I've had a good search through here, but can't find anyone with the same problem as me.

Last week, i moved the car out of my drive with the spare key (no remote blipper on it), so I put it in the door lock to unlock the car. From then on, when I use the remote blipper, the drivers door won't unlock, and I have to do it manually. However, it will lock when I press the blipper to close it.

I think that unlocking the door manually may just be a coincidence, and that hasn't caused it - but what is it likely to be? I'm outside warranty, so will be doing repairs myself, so the cheaper the better

Any ideas?

Could be a computer gremlin try removing the battery for 5 mins or doing a software reset via the instrument cluster.

[feenster]

Already tried both of those, unfortunately to no avail.

I wonder if it is just the rod in the door is loose or misaligned. Its odd that it will close but not open? Almost like it doesn't have enough "push" to raise the pin?

I have the exact same problem on my passengers door... Don't know wheather this is a gremlin or not, but the door lock locks, but won't open...

[mini_macky]

have the same problem with my 02 MC what could be the cause? hmm...

Same problem here on the passenger door. The strange thing is I had the problem for 2 months and then the problem was gone for a week. But now it's back again!
How do you reset the computer?

[feenster]

Humm, mine gets stranger. The door locks fine from the remote blipper, but won't unlock or lock from the switch on the dashboard!

Looks like I will be dismantling the car at the weekend :-S

Didi you find something?

[feenster]

looking forward to your findings, feenster

my driver's side door locks using the key, doesn't unlock using the key & it doesn't respond either to the switch on the center console so i have to manually push it downward when driving

Oooohhh, I'll be following this thread with great interest. For the past couple of weeks, the passenger door on my '03 MC CVT has refused to lock OR unlock with the key or toggle switch inside. Another interesting thing is that I've always had the locking once the car gets up to speed turned off, but it randomly has started locking every now and then. I think I've got some electrical gremlins...

[feenster]

Yep, that seems to be the issue here. I took the door card off and had a good hunt around. I think the problem is an electrical gremlin - the control box in the door (behind the door handle) should be receiving the correct signal to open the doors as it does to lock the doors. This theory is compounded by the fact that the toggle switch doesn't work - this should be sending the same signals too I think.

So, in summary, I think it is electrical. I tried to take the control box out of the door yesterday, but it was too well attached for me to do it. I will give it another go at the weekend, but I'm not hopeful of finding any fixes out.

Anyone replaced their door control box (actuator?)?

So do you think a softwareupdate or a reset would do the job?

I have mine set to go in for this problem on June 5th.
Drivers door locks with the fob, does not unlock with the fob or when I drive away and doesn't work form the dash switch at all.

I'll report back after that.

Nice! Looking forward to your response...
