Best Answer

The door/trunk locks run off a vacuum system. The pump is located under the rear seats. If you have this sort of problem with the locks, you can typically hear the pump continuing to run for perhaps 45 seconds after you have locked the doors/trunk. Diagnosis: you need a new lock, or a vacuum line has a leak. Either way it's a relatively simple repair for your mechanic. Of course, if you have a Chilton's, and want to trace the lines or replace the lock, then you can DIY.

How do you lock the trunk on 1992 Mercedes 190e?

On my 1992 190E I can lock the trunk with any of the keyed locks. If you lock the doors, the trunk locks and if you lock the trunk, the doors lock. In other words all the keyed locks are electrically interconnected. In reality the locks are not electrically interconnected. There is a pump in the right side wheel well of the trunk, it uses vacuum to lock all the locks and pressure to unlock them. Although the pump is powered electrically, the locks are not.

How do you disable the automatic door locks on a Chevy Avalanche?

If the Avalanche is anything like a 2003 Chevy Silverado, you can program the door locks as follows: 1. With vehicle off, Pull back the High Beam headlight lever (High Beams are on) 2. Turn ignition key on and off twice (ON, OFF, ON, OFF) , then release the headlight lever. Your vehicle should respond my locking or unlocking the doors. 3. You can now PROGRAM your locks by pressing a three button code, using the unlock/lock buttons on your driver door. Your manual should have details of the buttons you should press. For example, Press Lock, Unlock, Unlock, - and your code will tell your when to unlock, or to unlock at all. Here are some of the possible Combinations (A and B) A - Do not Lock Doors Lock All doors When Vehicle Is Started Lock All doors When Vehicle is placed in DRIVE Lock All doors when Vehicle reaches speed of 5mph. + B Do not unlock doors Unlock Drivers side door only - when placed in park Unlock all doors - when placed in park Unlock Drivers side door only - when key is removed from ignition Unlock All doors- when key is removed from ignition. These are a few examples, that can be programmed by pressing the unlock/lock buttons (three times).. If you don't have your manual, then you can try random combinations. Once you enter your 3 button combination, the vehicle exits programming mode. You can now start the vehicle and test the locks. Or: Repeat the process.
