Question about Mercury Cars & Trucks
So this is what it takes to replace rear brake rotors on a 2003 Mercedes E320;
1) open the bonnet (hood) of the car and loosen/remove the cap off of the brake fluid resevior.
2) remove outer spring clamp from brake assembly (it clips in to the iner edge of the holes of the caliper).
3)using a 7 MM allen wrench, remove the brake caliper.
4) using 18 MM box wrench, remove the caliper housing assembly off of the wheel hub.
5) using a star wrench, unscrew the rotor locking screw from the rotor
6) squirt some liquid wrench on the rotor hub and knock the rotor with a hammer to work the liquid wrench in.
7) using the same hammer, knock the rotor off the hub.
8) using a metal file, lightly file old residue off of the hub and place the new rotor on the hub.
9) set the hub by screwing in the lug nuts and then screw in the hub locking screw using the star wrench, then remove the lug nuts.
10) reinstall the caliper housing assembly onto the wheel hub using the 18 MM box wrench.
11) push back the brake claiper piston to its home position and install the inner brake pad (the one with the snap clips)
12) insert the outer brake pad in the claper housing assembly.
13) slide on the caliper housing with the inner brake pad in place (over the outer brake pad) and screw in the caliper screw rods using the 7 MM allen wrench
14) on the right wheel brakes, DO NOT FORGET to slide in the brake sensor (the one with the black connector) and connect it to the connector on the caliper housing.
15) be sure to reinsert the spring clamp onto the outer brake assembly to set the assembly squarely onto the wheel (there should be no wiggle in the brake assembly after the spring clamps are installed).
16) finally mount the wheels.
17) you can bleed the brakes at this point to release any trapped air (which is unlikely) but be sure to pump the brakes after starting the car BUT BEFORE MOVING IT to re-preassurize the brake system before driving the car.
17) ONE WEEK LATER - recheck brake assembly to ensure all is okay and brake fluid.
This proposed solution is for a 2003 Mercedes Benz E320 and NOT a 2005 model as stated by the limited option selection provided by FIXYA.com when initially describing the problem.

Floor jack- jack car up and put a jack stand under it. A tire lug to remove tire. A 36 mm socket to unbolt axle shaft sticking through bearing hub. Next a Brass hammer with a block of wood. Next center wood on axle shaft sticking through bearing hub and hit with a 4lb brass or steel hammer with a wood block on shaft. Next you need a 10mm or 12mm socket on back side of bearing hub should have 3 bolts holding it unbolt. Last use a pry bar and gradually pry bearing out and no there not pressed in like a lot of people think.
(Socket sizes maybe different)
If you take it somewhere it would cost about $800 and up.

you need to find out witch door jam switch it is they are about $40 each you can take a ohm meter and check the electrical connection. place the wires on the pins with it open then check when you press the button to make sure that the numbers change if no change on the ohm meter then that is the bad door switch

I have the same problem as you, with the same car. It seems to be moisture related. Mine is two months out of warranty, so I inspected the rear wheel speed sensors, like your dealer said. There is a TSB (technical service bulletin) concerning this problem, so Toyota/Scion do indeed know that these sensors are failing. In my case, one of the sensor connectors was broken when the car was assembled, which bent the tiny sensor pin, which broke off while I was attempting to get the connector plugged back into it. I make my living as an electronic technician so I'm not inexperienced with such things. Anyway, rumor has it you're looking at over $700 at the dealer to replace one sensor, since you cannot replace only the sensor. The part (rear hub assy) can be obtained online for $290, plus the wire for $37. All in all, it's a crappy situation. A known problem concerning key safety systems on the car, and Toyota neither issues a recall nor do they extend the warranty.
