    hi thanks for responding. i have tried all the window reset procedures that are posted on the forums. none of them work. i can drop the passenger side window by moving the latch in the door but the drivers side doesnt respond. i think the microswitch that tells the window to drop is either not in the right position or is defective. before i take things apart i just would like more info on the switch, its location to the door latch and the problems i may encounter. thanks

As long as it's not a mechanical malfunction, your car's position memory just needs to be reprogrammed. So, put the key in the ignition & place it in position 1 (ACC). Hold down the affected window switch for an additional five seconds after the window goes all the way down to perform a memory reset. Let this window back up, let go, pull the keys back out of the ignition, & open the door.

The door on my 2005 Ford Freestyle will not latch what can I do


depends if its not lined up with the post upon closing or is the latch it self not latching, take screw driver and trigger the latch to lock position then use the handle to open it if that is working then check lineup on the post and see if the door hinges are worn allowing the door to drop if so replace the hinge pins.

BMW Z4 convertible top opened and now wont close. Motor runs then stops. Latch is stuck and the emergency pull cord will not release. How do I get to the latch to free the top?


try a spray lubricant into the motor mechanism and grease any visable wire cables that run from/to motor ,not the electrical cables the bare wire winder cables,also grease/ lubricate any accessable pivot/hinge points , gently pull the cord and gently push the roof back and forth occasionally trying motor with a bit of patience this should get the roof moving , also look for anything that may be snagging the roof/mechanism as there is a pressure protection system to stop the roof being fully closed on say someones hand so preventing injury

Driver door on 2003 z4 bmw wont open


Sometimes the connection behind the door panel causes this problem. It is a wire that fits into a hole on the inside of the door handle. Be careful when you pop the door panel off. Use the tool, which is a flat thin pry bar. The wire looks like a thick metal coat hanger and fits in the hole.

Lock on drivers side will not open


the most common problem is lock solenoid (inside door) needs to be replaced. Before replacing try re-syncing locks. To do this, you need to lock all doors from passenger side, unlock from pass side, re-lock from pass side - then try drivers lock.

BMW 1996 328i E36 cnvertible Driver side window will not go down and back up when door is opened and then closed? It did this once before but started working but now it has started again.


micro switch may have failed. have a very close look in the door latch fixed to the car...there should be a very small square pressable switch.. open the door and press your finger inside the latch against the little button, the window should drop and raise. If you dont have one there its on the inside of the door lock mechanism.

Power rooftop only lock and unlocks and does not open or close by the switch


check the partition in the trunk to make sure it is fully in the down position. if the light on the switch is orange then the microswitch is not depressed. if the light is red and the top still wont open then you have a bad pump due to water ingress from clogged up body cavity drains. this is an expensive repair.

Z4 Central Locking problem - drivers door.


looks like you will need a drivers door lock actuator (contains the latch)if the door will not unlock with the remote either.the lock cylinder usually will fail since you had to use it everytime to unlock the door. the lock cylinder is vin specific so expect a delay when its ordered from the dealership.i would probably expect around $800 for the complete repair, kinda pricey but the dealership will go out of its way to retain a customer.
