Mercedes Repair Questions? Ask a Mechanic for Answers ASAP
Hi, welcome to Just Answer. My name is Marty.
Would you like me to call you on this problem?
Sorry for the wait I was stuck on another call.
Fuse #5 and #19 in the rear fuse box next to the battery are for the PSE pump.
To reset the pump you would remove both fuses for a few seconds.
Let me know if you need anything else.
If the fuses are good and the doors do not lock with the remote or with the button on the console you will need to replace the PSE pump.
Fuse #5 is a 25 amp fuse. Fuse #19 is a 40 amp fuse.
As long as all of the fuses are good you are fine.
Removing and reinserting the fuse resets the pump. If it doesn't work then the pump is bad.
If nothing works when using the key or the switch on the console you will need to replace the pump.
The pump is right there next to the battery in the foam box.
Sorry for the wait, I had to leave to drive home. I'll reply back later tonight with a price on the PSE pump.
