what i srelay "H" for?
I think my B and H relays in the fuse box of the driver side engine compartment were mixed up (2007 S550 W221). I was told B is for Airmatic compressor but don't know what H is for. They are both green and 5 legged.
The car ride is little rough, feels like suspensions are overpresurized. At first I thought the relay B was faulty so, I took that relay to the dealer and they gave me a replacement for $10 (part#A002 542 76 19).
Questions:
1. Does anyone know what relay H is for?
2. What is the correct part# for B relay?
3. Are B and H relay interchangable?
Please assist.
Thanks
