1999 Cab4 Tiptronics with navigation (missing CD)

Can someone tell me if the following is normal or if I can change:

Memory seat buttons do not work.

When I open the door from outside, interior lights do not come on. (If car is running, open door I get interior lights)

Key in door lock will not roll windows up or down as I have seen in some posts. Can this function also control the top? Mine will not.

When I turn off and remove key, dash display of odometer reading stays lite for some time.

I am about to remove door panel to change window regulator. Is it best if I disconnect battery to keep air bag from going off? What will I loose by disconnecting battery?

I hope this information will help:

Memory Seats:

1. Check the fuses. If you don’t have a diagram (folded paper attached to the back of the fuse box cover), check fuses E-2, E-3 and E-4.

2. If the fuses are OK, the following procedures are taken from a MY02 Owner’s Manual.

Seat Memory

Individual seat and door mirror settings can be stored and recalled for the driver's position.

/?\. Warning!

Risk of crushing. Due to risk of crushing from uncontrolled recalling the memory of a seat setting, do not leave children in the car unattended.

Operation with person buttons 1, 2

Storing seat position:

1. Switch ignition on.

2. Set the desired seat and door-mirror positions. If you wish for the passenger's mirror to swivel down as a parking aid when reversing, reverse gear must be engaged when the seat position is stored.

3. Keep memory button M depressed and additionally press one of the person buttons 1 or 2.

The individual setting is now stored under the desired person button.

Recalling seat position:

1. Switch the ignition on or open the driver's door.

2. Press person button until the seat has reached its final position. The mirror setting will be completed even if the person button is not kept depressed.

Note:

Automatic seat adjustment can be interrupted immediately by releasing the button.

Operating with the remote control of the vehicle key:

Each remote control (up to four) can be assigned an individual seat and door mirror position. The stored seat and door mirror position is set automatically when the vehicle is unlocked using the corresponding remote control. Each key is identified with a different colour.

Storing seat position:

1. Switch the ignition on with the desired vehicle key.

2. Set the desired seat and door-mirror positions. If you wish for the passenger's mirror to swivel down as a parking aid when reversing, reverse gear must be engaged when the seat position is stored.

3. Keep memory button M depressed and additionally press the ~ button (beside the memory button). The individual setting is now assigned to this remote control and to the ~ button.

Recalling seat position:

Unlock the locked vehicle or luggage compartment with the remote control. The stored seat position is set automatically. The seat position assigned to a remote control can also be recalled with the ~ button if the corresponding key was used to unlock the vehicle or to switch on the ignition. If no seat position was assigned to a remote control, the ~ button will not work.

Note:

Automatic seat adjustment can be interrupted immediately by pressing the central locking button or any memory or seat adjustment button.

Clearing the stored seat position:

1. Switch the ignition on with the desired vehicle key.

2. Simultaneously press and hold the ~ button and person button 2 for at least 5 seconds.

Opening and closing the windows with the key:

Comfort function when unlocking the vehicle at the door lock I> Coupe, Targa and Cabriolet with hardtop:

Unlock car with the remote control. Hold car key in door lock in the unlocking direction until the windows have reached the desired position.

Cabriolet without hardtop:

Unlock car with the remote control. The windows can only be opened with the convertible top open.

Comfort function when locking the vehicle at the door lock I> Coupe, Targa and Cabriolet with hardtop:

Hold car key in door lock in the locking direction until the windows have reached the desired position.

Cabriolet without hardtop:

The windows can only be closed with the convertible top closed.

When you shut off the ignition switch and remove the key, the digital displayss in the instrument cluster stay illuminated for 4 – 5 minutes. If the digital displays stay illuminated indefinitely, insure that neither of the two adjustment knobs (instrument illumination/trip counter reset or the clock adjustment) is not stuck in a “pushed in” position. Incidentally, pushing in on either knob will cause the digital displays will illuminate for 4 – 5 minutes if they are not already illuminated.

The below is a link to a door panel removal/replacement DIY procedure:

Yes! Disconnect the negative lead of the battery before working around the air bags.

You will need a code to get your nav/radio to function. If you don’t have the code(s), you will have to visit a Porsche dealer. Unfortunately, the radio code service offered here on RennTech is not set-up to find the nav/radio codes. You will also have to re-teach the windows how to operate in the one touch mode.

Storing end position of the windows:

1. Close the windows with the rocker switch.

2. Press and hold front half of rocker switch 3 or 4 seconds to store the up end position of the windows in the control unit.

3. Open the windows with the rocker switch.

4. Press and hold front half of rocker switch 3 or 4 seconds to store the down end position of the windows in the control unit.

If you don’t have an Owner’s Manual, order part number: WKD 996.021.00 (MSRP $35.24 + tax).

I don't have any suggestions about the interior lights problem. I hope the above helps.

Thanks for all the input but all negative. Fuses good. Still no seat memory function with buttons or key.

Key will not open and close windows. No lights when I open the doors.

Any other ideas? Could all of these items be turned off in the control unit?

[logray]

I wonder if this is because of a door microswitch or ignition switch.
