 Central locking pump + motor
Hi all, I'm a fresh new user and got an A Class W168 which one had problem with the vacuum pump.
I examined the pump, the motor has gone (burnt)...
I just replaced it with a new similar one (choose the same ohm value,
mine was 1.2 ohm) and it worked as well. Then it has gone again.
I bought another motor for 5$, but this time I noticed the motor
produces heat. Why? Coz it runs for about 30 seconds and
in a closed case, it burns itself.
I think I got a mechanic/electronic problem with the vacuum pump' circuit.
5 seconds is quite enough time to un/lock the doors, however pump's
interior phenomatic switch doesn't sense?? the doors locked and continue
to pump air, until main unit cuts the electricity.
For the people who have problem with vacuum pump motor;
yes, you can replace the motor with an ordinary one, the only thing to do,
you should trim end point of the rod/axle to recap miniature plastic guide. |
