Trying to figure out why there is no power to switch for gas cap cover. In doing so, a friend of mine used a jumper wire connected to gas cap cover switch harness and got the gas cap cover motor to engage and open the cover. Our suspicion is that there is no power to gas cap cover switch due to a bad relay; also interesting to note that all three passenger door locks do not work remotely nor at the driver’s door switch. Can only lock and unlock the drivers door and the hatch with key and with remote.
Is the gas cap cover power issue possibly related to the same relay that enables the three passenger door locks???
If it is a relay that is bad; which relay is it and where is it? Dealership in Fargo did not have an answer though I suspect I would have to buy the relay from the dealership since it appears no one else carries such a relay.
We came across a number of relays under the dash but my friend was not comfortable removing and or experimenting with the relays since he does not have much experience with Passats.
I have photos of the relays that I can send if that helps. It appears that all or most of the relays have large numbers on them.
Any help is greatly appreciated!
