Is there possible a simple answer? My doors unlock fine with the key, or the button on the armrest. but will not lock. I can hear the power trying to activate the lock but it doesn't have the power to complete the task. Any ideas?

 

try disconnecting ground on the battery wait a min and reattach.

 

Thanks Racerguy. I'm about two hours away from the house and I will give it a try when I get back. I'll keep you posted.

 

Let us know how it goes - my '02 vert does the same thing, but only on the driver's side.

 

I tried disconnecting the ground wire and it's still the same. What's the next step? Now there are two of us looking for help. Thanks to everyone in advance.

 

That happened to me on both door (diffenent times). It was the door lock actuator. If you have warranty it will be covered.

 

My driver side door won't unlock at times even though the passenger side does.

Luckily with window valet, 3 hits of the unlock button and down comes the windows. I just reach in and unlock!

Now to get that stupid turn signal / hazard light switch connection looked at. I hate the "Casper Effect" signals.

 

Don't panic.
Give it a day or so if you can stand it. My window wouldn't go down on pass side -then after a few days it started working again-
Same thing on turn signals happened to me once -
Went crazy trying to trouble shoot and never found a reason. I didn't fix it - it fixed itself -

 

It could be a bad ground, or a loose connection to the DCM or a bad relay in the DCM or the board in the DCM could be bad.

mine did exactly the same thing... in the end it ( after replacng the relay) it turned out to be a bad DCM

 

RWS. Thank you. The link you provided describes my problem exactly. Including the embarrassment of having the alarm go off when you open the door! I'm headed in the right direction now.

 

Thats the normal problem

With mine the key was fine and just the passenger door lock gave problems. The Dealer replaced the door lock actuator ("Module Local Interface Unit Door Left") under warranty.

 

2 relays one for lock and one for unlock

Yep, our C5's doors quit locking via the fob last weekend. I opened the passenger door (thinking that my wife had

unlocked it via the fob), but to our amazement/my embarrassment - after I had inadvertently set-off the C5's alarm, we both discovered that neither the driver's door nor passenger's door were actually ever locked.

I wonder how long this has actually been going on, since we've never attempted to unlock the doors manually before...without utilizing the key fob first.

BTW...very informative link you provided...thanks.
