Part 5 - Installing the wiper system
I have done all the work on a 2000 S500 - but this applies to all other W220 cars such as S430 and S320. I have recorded the footage but editing is taking time. So, as I finish editing each part, I will be publishing them. At the end, I will probably have one last video that includes all the parts.

I got a w220. Pulled vacuum, there was pressure in system when I set my gauges up initially. I tried to put Freon in, there is no leaks in the system. it showed the same pressure on the high and the low side, I cleared fault code with carsoft… I’m sorta stumped on best way to diag this.
Hi, is that with the compressor turned on? If yes, you have a bad compressor.
@@masood-tv yeah, with Freon charged and a/c code cleared and ac turned on.
How much is this service if you don’t do it yourself?
Everything I do in the series would cost a couple thousand dollars...
