where is the fuel pump relay located in a 1998 mercedes slk230?

the fuel pump is located beneath the left rear door of the car it is exactly in the edge if the body if u take a look under the left rear door u will find it, but i afraid u may have to change the entire pump because of this relay, it is hard to fix the relay.

Fuel pumps are usually located in the gas tank...Hope this helps.

Go to the dealer and they might help you break the code for free. ask them if they are going to charge money though! because they are such a rip off.

It's under the back seat.

Your a/c system is probably low on freon if the button will not go out of economy mode when pressed. I would have the a/c system serviced and inspected for leaks
