2005 Mercedes ML500 auxiliary fan relay.
This vehicle needed a lot of repairs due to maintenance not done. The auxiliary fan was inoperable so I replaced it. While putting everything back together, the electrical connectors hit the frame and caused a spark at the battery that I forgot to disconnect.
The new fan tested fine so I went on to check all of my AC relays and found a reference to the relay attached to the positive battery terminal. I’ve never seen a relay like this. I did find a suitable replacement and the properly fitted holder on Amazon.
I’m confident that the car won’t overheat at stop lights and will be moving on to replacing the pads and rotors. Once the brakes are done, I can shift my focus to the inoperable AC.
I love it when they run, even better if they stop and it’s a bonus if the AC works.
