I replaced my rear tank pump this weekend with no issues at all. I decided to tackle the upfront I/C pump next to the heat exchanger too. After pulling the Meziere off, I tested it to make sure it was in fact dead. To my surprise it cranked right up, and start spinning like a top.

So I got under the car and checked my fuse I put inline with the pump, and it checked out ok, not blown.

My question is, what should I check next up stream, as it does not seem to be getting power. Is there anyother fuse that controls that circuite

Thanks fellas.

Open the trunk lid,take the side cover on the driver side off and look in the fuse/relay box. If I remember correctly the first or the second relay (from bottom to top) is the one that controls the pump.
Good Luck!

Thanks homey, I will check that critter out. I was trying to find the electrical schematic chart online but no luck.

The chart with a bunch of other useful information is in the sticky DIY addition that I made, but I'm feeling like a nice guy today so I'll post up the fuses and relays from member Kropf https://mbworld.org/forums/e-class-w...les-chart.html

I'm suprise you still use the stock wiring for Mezeire pump. I ran my front pump to the fuse box in the engine bay so it's on when the key is on. Next upgrade I'll run the wire directly to the alternator so it'll get the full juice.

Hi

How did you go with this?

Did you work out which fuse is used for the standard intercooler pump?

If so please share the details for me.

Hi


Thanks for the replies. Yes my fuse number 4 was blown so I replaced it and all is working again.


I wonder why the fuse blew after working fine for nearly 2 years?
