i am doing majow work on my 81 300sd with about 400k on the block

once i get done these things i need to solve...

the first issue is that there are times when i have seriously wet carpet behind the passenger seat...have no clue...

second issue is the tachometer works only when it wants to....

the issue that kills me the most is that i have no hazard lights....after changing switch, fuses, relay behind dash....is there another relay by the fuse box that i am missing?

i'll take any and all hints/suggestions...
