Mercedes-Benz S500 Blower Motors

To keep your Mercedes-Benz S500 comfortable in hot and cold weather, the climate control system depends on the blower motor to move warm and cool air into the cabin. A faulty blower will disable the heat and air conditioning inside your car, which in extreme weather will make it uncomfortable to drive. With a selection of replacement blower motors for Mercedes-Benz S500, you can find what you need to keep your climate control system in working order when youre behind the wheel.

What causes the Mercedes-Benz blower to stop running?

Usually, the cause is an electrical connection or component that fails in the vehicle rather than the motor itself. Here are the common scenarios that can happen:

  • Blower only runs on one-speed setting: If the only blower runs on one setting, but not others, the problem is not the motor but an electrical relay that controls its speed. Check the other components for problems.
  • Blower doesn’t run: If the blower doesnt run at all, check the fuse and wiring for obvious failures. If these check out, then test the motor to see if it’s gone bad.
  • Blower runs, but noisy or slow: A mechanical failure in the motor or the fan can cause squealing, ticking, or grinding noises. It can also cause the blower to lose speed or freeze up completely. In either case, you’ll need to replace the fan blades or the motor.
How do you test the Mercedes-Benz S-Class blower motor?

If the blower doesn’t run in your model Mercedes-Benz, you still need to make sure it’s the problem and not something electrical elsewhere that’s stopping it. The easiest way is to test the motor directly to see if still runs. Follow these steps.

  • Take the blower motor out of the car so you can test it on a workbench.
  • Use a couple test wires with alligator clips and a 12-volt battery as a power source. Attach one wire to the positive post on the battery and the other wire to the negative post.
  • Connect the two wires to the power and ground pins on the motor’s wiring harness.
  • If the motor runs when you give it power, then it’s fine and doesn’t need replacing. If not, you’ve found the problem; you need a new motor.
Where is the blower motor in the S500?

The blower motor is found behind an access panel above the passenger seat’s leg space. For detailed instructions on how to remove the panel, refer to your repair manual for the S500. The blower’s fuse is located under the hood, along with the driver’s side. It is an inline fuse.
