I replaced the battery...

I replaced the battery in my s430 Mercedes and the door locks wouldn't work also the trunk wouldn't open with the inside switch or the remote. Checked the fuse in the rear and it was blown I replaced the fuse and it blew again.

Mechanic's Assistant: Most vehicles have two fuse panels. Have you located both?

Yes the one under the hood was not blown but the 20 amp in the back blew twice.

Mechanic's Assistant: What year is your S430?

2000

Mechanic's Assistant: Are you fixing your S430 yourself? What have you tried so far?

Yes just checking fuses using the fuse diagram

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

That's it for now

Ask Your Own Mercedes Question

can you tell me what fuse you replaced that blew? was it fuse 62 for the pse?

if so then the pse module will need replaced. the motor most likely shorted .

this is a very common issue. here is the location of the pump/module.

its the drivers front area of the trunk.

hope this helps.
