Clock in 99passat minuts keep running like countung down

Which relay are you talking about? I can't post wiring diagrams here because of copy-wright issues.

autozone.com has free wiring diagrams. Hopefully they will have the one you need. Go to the site, register your vehicle, it's free. Click on "vehicle repair guides", follow the links, there should be wiring diagrams for your vehicle.

check the alternator drive belt for condition and tension. Have the out put of the alternator checked . have a load test done on the battery as you may be trying to charge a dead cell.. The indications are that the alternator cannot keep up with the demand on the electrical system and that means battery or alternator.

your clock is broken, the only fix is replacement

Keep pressing the knob that you use to adjust bass, treble, fade, ect, keep going, you will get to clock. Next one after clock is set the clock. Then you have to be quick about it, turn that same knob to increase or decrease the hour, then it will move to minutes and turn till you get the right minutes.
You really have to be quick about it, it took me several times before I got it completed.
if anybody has the 2.5S model 2010 Altima >>> hold the Clock button for 2 seconds, when the words SEEK and TUNE appear, press the Seek button (top LEFT) up or down to change the Hour ... then press the Tune button (top RIGHT) to change the minutes ... press Clock again to end adjustments.

No solution yet... mine keeps running slow - supposedly there is a disc that the dealer can put into the CD player to fix some clock problems, otherwise you have to take out the whole unit & replace it, is what I'm told - people on the phone keep ducking the question & directing me to a dealer 500 miles away.

There are three buttons, let's call them 1, 2, and 3, from left to right.


Clock
Time setting

A. 12 AM, PM or 24.00 h
With the clock in the time readout mode, keep
button (2) depressed for 4 seconds -12 AM, PM
or 24.00 flashing. After pushing button (1), either
a 12-hour (AM + PM) or a 24-hour setting
program can be selected. If you only want to
change the display mode, push button (3). The
clock then returns to its normal timekeeping
function.

B. Hours
Push button (2) a second time - hour display
flashes. Set hour by pushing button (1). After
pushing button (3)*, the clock returns to the time
readout mode with new hour setting.

C. Minutes
Push button (2) once more - minute display
flashes. Set minute by pushing button (1). Upon
pushing button (3)*, the clock is started -
accurate to within 1 second.

Stop watch function
The stop watch can only be set in motion if the
clock is in its normal timekeeping mode and not
during setting operations.
A. Push button (3) - 00:00 display appears;
B. Push button (1) - stop watch is on;
C. Push button (1) a second time - watch stops.
(Additional times can be added by pushing button
(1) again - stop watch keeps running. Push button
(1) once more to stop timing.)
D. Push button (2) - 00:00 display appears;
E. Push button (3) - normal timekeeping mode.

If button (3) is pushed during operation A and
B, the setting procedure must be restarted
(push button (2)).

FROM THE OWNERS MANUAL

8. Clock: Press and hold CLK button until the
hour digit flashes. Turn the volume
control to increase/decrease the
hours. Press again to set the minutes. Turn the volume control to
increase/decrease the minutes

I believe that if you HOLD DOWN the "clock" button and press "seek" for minutes and "tune" for hours you should be able to reset your clock. Remember that if you press the + "seek" you will increase the minutes and if you press the - "seek" you will decrease the minutes. The same for "tune". The left will decrease and the right will increase hours. If this doesn't work, there is something wrong with the contacts behind these buttons, or some other problem.
Good luck.
