BMW E38 door lock and windows not working
Why do the E38 driver's door lock and windows not work when the other doors do?
The cause can be the driver's door control panel. Replacing the panel with a working one fixed the fault. There are different versions of the panel, for example in the mirror adjuster knob, so check the version. Also measure the fuses one by one; a fuse left in the wrong place has stopped the central locking from working.
Why does the door handle not open the door or the door close badly?
In frost the mechanism can freeze. The cable from the handle to the lock can be disconnected or rusted solid. If the door acts up, remove the door card and check the lock mechanism and the cables. An aging door servo can also weaken. If the door does not stay open, the door check strap is probably worn.
Why does the window auto function not work and how is the regulator repaired?
The auto function is a codable feature, and it is set separately up and down for each door. The rear window regulator is cable-driven and is held by three Torx screws and one hard-to-reach bolt. A broken cable means the regulator has to be replaced.
How is the E38 door card removed?
1. Lift the lock button cover with a sharp object and remove the button. 2. Remove the light and the window switch with a screwdriver. 3. Pull the card off from the bottom edge and protect the fabric. 4. Feed the wires through the card. Install in reverse order and guide the lock pin through the hole.
