Post by Don TuttleWhere might I get a hazard switch (part 25290-060A00) for a 1988 Sentra?
If it's just the underlying switch (not the plastic cover), then
possibly any car parts store could have something that is at least
compatible.
A proper Nissan dealer repair centre might be able to get one - it may
mean waiting for it to be shipped from Japan though.
Otherwise you could try a wreckers yard.
