Ok so I had a usuall problem on my 1995 E300D, tachometer dead, rough idle and AC not working. Took out OVP relay, (for some reason the relay only had 1 10amp fuse and 7 pins vs 2 10 amp fuses and 10 pins others have reported in their 1995 cars) the fuse was blown, replaced it cleaned pins and put everything back togeather. Tachometer now is working and idle is nice and smooth! I don't even think I need motor mounts anymore, but I have ordered them already
oh well will be a spare.
The A/C is still not working, does not look like the compressor is engaging. Any ideas? Could it be the OVP relay is still preventing the AC from working? But everything else works now...
