    I have a 04 Cruiser and the locks will unlock and lock by themselves all my switches work except for the passenger door switch could this switch be the problem? I have unhooked the Batt to reset the computer and it still happens.

    I have a 2001 Pt Cruiser Limit Editon and just started doing this, Just as with Nealwix My passenger side switch is working properly too. It will unlock but not lock the car. Maybe this is the problem. Did Nealwix replace the switch and correct the problem?

    When locking all the doors, the driver side does not lock, it has to be locked by hands. Hatch also locks the three door, but the the driver's side

    The door ajar switch is inside the latch in the car door. It is actuated by the latch loop on the door frame hitting the switch. Something is wrong with the alignment of the switch. I am trying to find out how to adjust it myself. It may require an entire latch assembly replacement. :(

    PT Cruiser door ajar switches are built into the door latch, just beyond the claw hook that locks onto the loop that is on the door post. The front shoulder of the door post hoop activates the switch.

Dead battery even when 2001pt,cruiser is not runing

You haven't given a lot of information to go on and I don't really get what you mean when you say the battery is dead even when the engine isn't running.

Have you had the battery tested? Most any parts store or repair shop can test a battery for you and tell you if it's good, bad, or just needs charging.

If the battery checks out okay poor connections at your battery could be the problem or the cables themselves could be so corroded that they no longer are capable of flowing current. If there is corrosion on your battery terminals that is a place to start. Use baking soda and water to clean the clamps and posts (you'll want to remove them for this), also a wire brush for tough spots.

Does the battery go dead after a few days or overnight? If after a few hours or overnight then something is most likely draining the battery. Do you have to jump start your car after it sits for a few hours? If so then look for dome or glove or trunk lights being left on, brake lights sticking on, aftermarket stereo or alarm wiring issues, or other items staying on after the car is turned off that would drain the battery. Bad door or trunk switches for the dome lights can cause the lights to stay on.

You can test for ignition off draw with the right testers to see if it's within specs. You could also pull the IOD fuse in the block under the hood to see if that stops the battery from going dead overnight.

If it goes dead over the course of several days then a more likely suspect might be the charging system.

But these are all just general ideas. We need more specific information to really hone in on any one area. But the first thing to do is get that battery checked and given a clean bill of health.

How do I turn off the door alarm on my 2002 Chrysler PT? When I put the key in and unlock the door, the alarm goes off and doesn't stop until I turn the ignition on.

this is a standard warning to tell you the keys are in the ignition to help prevent them from being locked inside. This is a factory alarm and cannot be turned off

2001PT Cruiser door locks

The fuse is No.3 "DR locks" (near steering wheel)
If you take the fuse out the doors will not open itselves.

The root cause of the problem will be a microswitch inside the drivers door?

======FOG LIGHTS ============

1.At first take out the foglight's fuse before you battery is dead. (Fog lights stays "ON" even you leave the car).

2.You must replace the Multifunction control switch =(

Here is the photo of problem:
http://www.ptcruiser.fi/ptgalleria/albums/userpics/10010/normal_sumuvalokytkin.jpg

Fog lights are connected to pin 13,14.
Fog light switch is "B". Because the current is many Amps, contact surfaces are heating up.
After that the contact opening "C" is melting (made of plastic) so the fog light stays "ON".
