Fuel Door Actuator Replacement - Fuse?

Recommended Posts

I just replaced the fuel door actuator on my 1999 C2 and the fuel door still does not lock and I get a single beep when locking the doors with a key (remote does not work).  Is there a fuse to the actuator?  I have a Durametric and reset the codes but they return when I run the activations.  Is there a fuse to the motor?  If not, where is the relay located?  I have the Bently manual and it only addresses how to R/R the motor, not troubleshoot it.

You have two problems...

First check fuses.


61 is a door lock not actuating. Could be a bad microswitch.

12 relates to a door lock also.


58 No current in tank servomotor despite relay actuation

Possible cause of fault
- Short circuit to ground/open circuit in the wiring between the switching element for the filler flap and the alarm system control module
- Open circuit in wire between ground point 7 and alarm system control module
- Switching element for filler flap faulty
- Control module faulty

I just installed a new (aftermarket) door latch into the left door (drivers) along with a new right door latch and the codes persist.  It seems that the 3rd party eBay door latches have a function that is not supported by the US spec cars, causing the Code 12 condition.


 Is there a way to pinpoint which door lock is causing the 61?  I see other posts referencing looking at live values but I only see that under the DME in Durametric and not in the Alarm I32 section.

Ran through test point 53 in FSM for code 58 and everything checks out.  I tested the resistance on the old and new actuator and they were both in the min-40's so I don't think the old one was bad at all.


I'm going to go through test point 56 for fault code 61 next week.

To close out this thread, I checked the wiring with a multi-meter and everything checked out.  Since I tried to save money by using VW door locks, I bit the bullet and bought a pair of factory locks from the dealer.  The new factory locks fixed everything.  Windows now stay down when the doors are open, the interior door lock switch works, the lights go on and off as they should, the doors can be unlocked and opened without the alarms going off, the fuel door lock works when the doors are locked, and the alarm can be set with the key.
