Have Mercedes Questions? Ask a Mechanic for Answers ASAP
I checked for vacuum leak and there is none. The vacuum pump must be OK since passenger door and the trunk door are OK. This leaves the micro switch. Could this also be caused by a blown fuse? Is there a fuse for this and where can I find it?
Can you let me know how to read the value with a scanner? I can borrow one from Advanced Auto Parts store?
